Acquisitions and Discontinued Operations [Abstract]  
Business Combination Disclosure
Acquisitions
Acquisition of Holden America
In December 2022, we acquired Holden America, a manufacturer of market-leading multi-level vehicle securement and protection systems, gravity-outlet gates, and gate accessories for freight rail in North America. The purchase agreement included minimum additional consideration of $10.0 million, which is payable in installments of $5.0 million per year in each of 2024 and 2025. The purchase agreement also contained a provision whereby additional consideration could become payable based on the achievement of certain revenue targets, up to a maximum payout of $10.0 million.
The total additional consideration, which is included in other liabilities in our Consolidated Balance Sheets, had an initial estimated fair value of $20.0 million as of December 31, 2023 and is remeasured at each reporting period using Level 3 inputs. During the year ended December 31, 2024, the first installment of the additional consideration, totaling $10.0 million, was paid. This payment is reflected in our Consolidated Statements of Cash Flows, of which $8.0 million related to the initial estimated fair value is included in financing activities, and $2.0 million related to the remeasurement of the initial estimated fair value is included in operating activities. As of December 31, 2024, the fair value of the additional consideration was $10.0 million, which was funded in February 2025.
Acquisition of RSI Logistics
In March 2023, we acquired RSI Logistics, a data-centric provider of proprietary software and logistics and terminal management solutions to the North American rail industry. This transaction was recorded as a business combination within the Leasing Group, based on valuations of the acquired assets and liabilities at their acquisition date fair value using Level 3 inputs. Based on our purchase price allocation, we recorded identifiable intangible assets of $35.7 million, goodwill of $25.6 million, and certain other assets and liabilities. The identifiable intangible assets, with the exception of the trade name, which is considered an indefinite-lived intangible asset, are being amortized over their estimated useful lives, ranging from 5 years to 15 years.
See Note 8 for further information regarding goodwill and intangible assets.
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]
Discontinued Operations
Sale of Highway Products Business
In the fourth quarter of 2021, we completed the sale of Trinity Highway Products, LLC ("THP"). Upon completion of the sale, the accounting requirements for reporting THP as a discontinued operation were met. In connection with the sale, the Company agreed to indemnify Rush Hour Intermediate II, LLC ("Rush Hour") for certain liabilities related to the highway products business, including certain liabilities resulting from or arising out of the ET-Plus® System, a highway guardrail end-terminal system (the “ET Plus”). Consequently, results from discontinued operations include certain legal expenses that are directly attributable to the highway products business. Similar expenses related to these retained obligations that may be incurred in the future will likewise be reported in discontinued operations. For the years ended December 31, 2024, 2023, and 2022, we recorded expenses related to these obligations of $18.4 million ($14.3 million, net of income taxes), $17.0 million ($13.4 million, net of income taxes), and $21.4 million ($20.3 million, net of income taxes), respectively.

Derivative Instruments and Fair Value Measurements [Abstract]  
Derivative Instruments and Hedging Activities Disclosure [Text Block]
Derivative Instruments
We use derivative instruments to mitigate interest rate risk, including risks associated with the impact of changes in interest rates in anticipation of future debt issuances and to offset interest rate variability of certain floating rate debt issuances outstanding. We also use derivative instruments to mitigate the impact of changes in foreign currency exchange rates. Derivative instruments that are designated and qualify as cash flow hedges are accounted for by recording the effective portion of the gain or loss on the derivative instrument in accumulated other comprehensive income or loss ("AOCI") as a separate component of stockholders' equity. These accumulated gains or losses are reclassified into earnings in the periods during which the hedged transactions affect earnings. Derivative instruments that are not designated as hedges are accounted for by recording the realized and unrealized gains or losses on the derivative instrument in other, net (income) expense in our Consolidated Statements of Operations. We continuously monitor our derivative positions and the credit ratings of our counterparties and do not anticipate losses due to non-performance. See Note 9 for a description of our debt instruments.

Fair Value Disclosures [Text Block]
Fair Value Measurements
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for that asset or liability in an orderly transaction between market participants on the measurement date. An entity is required to establish a fair value hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair value are listed below.
Level 1 – This level is defined as quoted prices in active markets for identical assets or liabilities. Our cash equivalents and restricted cash are instruments of the U.S. Treasury or highly-rated money market mutual funds. The assets measured on a recurring basis as Level 1 in the fair value hierarchy are summarized below:
Level 1

(in millions)
Assets:
Cash equivalents$209.6 $78.7 
Restricted cash146.2 129.4 
Total assets$355.8 $208.1 
Level 2 – This level is defined as observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Interest rate hedges and interest rate derivatives are valued at exit prices obtained from each counterparty. Foreign currency hedges are valued at exit prices obtained from each counterparty, which are based on currency spot and forward rates and forward points. The assets and liabilities measured on a recurring basis as Level 2 in the fair value hierarchy are summarized below:

(2) Included in accrued liabilities in our Consolidated Balance Sheets.
Level 3 – This level is defined as unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. As of December 31, 2024 and 2023, we have no assets or liabilities measured on a recurring basis as Level 3 in the fair value hierarchy, except as described in Note 2.
See Note 2 for more information regarding fair value measurements involving Level 3 inputs resulting from acquisition activity. See Note 9 for the estimated fair values of our debt instruments. The fair values of all other financial instruments are estimated to approximate carrying value.

Note 4. Segment Information

Segment Reporting [Abstract]  
Segment Reporting Disclosure [Text Block] Segment Information
We report our operating results in two reportable segments: (1) the Railcar Leasing and Services Group, which owns and operates a fleet of railcars and provides third-party fleet leasing, management, and administrative services; railcar maintenance and modification services; and other railcar logistics products and services; and (2) the Rail Products Group, which manufactures and sells railcars and related parts and components.
Effective January 1, 2024, the Company modified its organizational structure to better leverage our maintenance services capabilities to support lease fleet optimization and to grow our services and parts businesses. The new structure resulted in a change to our reportable segments beginning in 2024. In connection with this organizational update, we aligned the maintenance services business, which was previously reported in the Rail Products Group, to now be presented within our leasing business. This change aligns with the way in which our CODM assesses performance and allocates resources. Consequently, beginning January 1, 2024, we report our operating results in two reportable segments: (1) the Railcar Leasing and Services Group, formerly the Railcar Leasing and Management Services Group, and (2) the Rail Products Group. These changes had no impact to our previously reported consolidated results of operations, financial position, or cash flows. All prior period segment results set forth herein have been recast to reflect these changes and present results on a comparable basis.
Our CODM is our Chief Executive Officer. Operating profit is the primary measure our CODM uses to assess performance and allocate resources to each of our reportable segments. Gains and losses from the sale of property, plant, and equipment are included in the operating profit of each respective segment. Our CODM does not consider restructuring activities when evaluating segment operating results; therefore, restructuring activities are not allocated to segment profit or loss.
Sales and related net profits ("deferred profit") from the Rail Products Group to the Leasing Group are recorded in the Rail Products Group and eliminated in consolidation. Sales between these groups are recorded at prices comparable to those charged to external customers, taking into consideration quantity, features, and production demand. Amortization of deferred profit on railcars sold to the Leasing Group is included in the operating profit of the Leasing Group, resulting in the recognition of depreciation expense based on our original manufacturing cost of the railcars. Lease portfolio sales are included in the Leasing Group, with related gains and losses computed based on the net book value of the original manufacturing cost of the railcars.
The financial information for these segments is shown in the tables below (in millions).

Dec. 31, 2024
Partially-Owned Subsidiaries [Abstract]  
Noncontrolling Interest Disclosure [Text Block] Partially-Owned Subsidiaries
Investments in Leasing Subsidiaries
Through our wholly-owned subsidiary, TILC, we formed two subsidiaries, TRIP Holdings and RIV 2013, for the purpose of providing railcar leasing services in North America for institutional investors. Each of TRIP Holdings and RIV 2013 are direct, partially-owned subsidiaries of TILC in which we have a controlling interest. Each is governed by a seven-member board of representatives, two of whom are designated by TILC. TILC is the agent of each of TRIP Holdings and RIV 2013 and, as such, has been delegated the authority, power, and discretion to take certain actions on behalf of the respective companies.
At December 31, 2024, the carrying value of our investment in TRIP Holdings and RIV 2013 totaled $130.4 million. Our ownership interests in TRIP Holdings and RIV 2013 are 42.6% and 30.5%, respectively, with the remaining interests owned by third-party, investor-owned funds. These investments in our partially-owned leasing subsidiaries are eliminated in consolidation.
Each of TRIP Holdings and RIV 2013 has wholly-owned subsidiaries that are the owners of railcars acquired from our Rail Products and Leasing Groups. TRIP Holdings has wholly-owned subsidiaries known as Triumph Rail LLC ("Triumph Rail") and Tribute Rail LLC ("Tribute Rail"). RIV 2013 has a wholly owned-subsidiary known as TRP 2021 LLC ("TRP-2021"). TILC is the contractual servicer for Triumph Rail, Tribute Rail, and TRP-2021, with the authority to manage and service each entity's owned railcars. Our controlling interest in each of TRIP Holdings and RIV 2013 results from our combined role as both equity member and agent/servicer. The noncontrolling interest included in the accompanying Consolidated Balance Sheets represents the non-Trinity equity interest in these partially-owned subsidiaries.
Trinity has no obligation to guarantee performance under any of our partially-owned subsidiaries' (or their respective subsidiaries') debt agreements, guarantee any railcar residual values, shield any parties from losses or guarantee minimum yields.
The assets of each of Triumph Rail, Tribute Rail, and TRP-2021 may only be used to satisfy the particular subsidiary's liabilities, and the creditors of each of Triumph Rail, Tribute Rail, and TRP-2021 have recourse only to the particular subsidiary's assets. Each of TILC and the third-party equity investors receive distributions from TRIP Holdings and RIV 2013, when available, in proportion to its respective equity interests, and has an interest in the net assets of the partially-owned subsidiaries upon a liquidation event in the same proportion. TILC is paid fees for the services it provides to Triumph Rail, Tribute Rail, and TRP-2021 and has the potential to earn certain incentive fees. There are no remaining equity commitments with respect to TRIP Holdings or RIV 2013.
See Note 9 for additional information regarding the debt of TRIP Holdings and RIV 2013 and their respective subsidiaries.
Other Investment in Consolidated Affiliate
In 2023, the Company and a third party formed Trinity Global Ventures to deliver railcars and provide warranty support services in Saudi Arabia. Trinity Global Ventures is owned 51.0% by Trinity Rail Group, LLC ("Trinity Rail Group"), a wholly-owned subsidiary of the Company, and 49.0% by the third party. Upon consideration under the VIE model of ASC 810, Consolidation, Trinity has concluded that Trinity Global Ventures meets the definition of a VIE. Trinity Rail Group has a variable interest in Trinity Global Ventures arising from its 51.0% equity ownership position. We determined that Trinity is the primary beneficiary and therefore consolidates this entity as we have the power to direct the activities of the entity that most significantly impact its economic performance. At December 31, 2024, the carrying value of our investment in Trinity Global Ventures totaled $2.6 million, which is eliminated in consolidation.
Investment in Unconsolidated Affiliate
In 2021, the Company and Wafra, Inc. (“Wafra”), a global alternative investment manager, entered into a railcar investment vehicle program between Trinity and certain funds managed by Wafra (“Wafra Funds”). As part of this program, a joint venture was formed, Signal Rail Holdings LLC (“Signal Rail”), which is currently owned 87.6% by Wafra Funds and 12.4% by TILC. TILC services all railcars owned by Signal Rail.
In May 2024, TILC and certain of its subsidiaries sold a portfolio comprised of 1,315 railcars and related leases to Signal Rail for an aggregate sales price of approximately $142.8 million. During the year ended December 31, 2024, TILC recognized a gain of approximately $18.8 million on the sale and approximately $1.4 million was recognized as revenue for services performed associated with the delivery of railcars with attached leases. In connection with the sale, TILC contributed $2.0 million of cash to Signal Rail. Signal Rail financed the May 2024 purchase primarily through an asset-backed securitization. To date, TILC has sold 7,775 railcars and related leases to Signal Rail for an aggregate sales price of $741.4 million.
Upon consideration under the VIE model of ASC 810, Consolidation, Trinity has concluded that Signal Rail meets the definition of a VIE. TILC has variable interests in Signal Rail arising from its 12.4% equity ownership position and its role as a service provider. We determined that Trinity is not the primary beneficiary and therefore does not consolidate this entity as we do not have the power to direct the activities of the entity that most significantly impact its economic performance. We will absorb portions of Signal Rail’s expected losses and/or receive portions of expected residual returns commensurate with our 12.4% equity interest in Signal Rail.
Our investment in Signal Rail is being accounted for under the equity method of accounting. At December 31, 2024, the carrying value of TILC’s equity investment in Signal Rail was $21.2 million, which is included in other assets in our Consolidated Balance Sheets. The carrying value of this investment represents our maximum exposure in Signal Rail.

The estimated fair values of our 7.75% senior notes due 2028 ("Senior Notes due 2028") and our 4.55% senior notes due 2024 ("Senior Notes due 2024") are based on a quoted market price in a market with little activity (Level 2 input). The estimated fair values of our secured railcar equipment notes are based on our estimate of their fair value using unobservable input values provided by a third party (Level 3 inputs). The respective carrying values of our revolving credit facility, 2017 promissory notes, TRL-2023 term loan, and TILC warehouse facility approximate fair value because the interest rate adjusts to the market interest rate. As of December 31, 2024 and 2023, we evaluated the fair value of the other equipment financing liability using Level 3 inputs and determined that the fair value approximates the carrying value.
Corporate – Recourse
Revolving Credit Facility – We have a $600.0 million unsecured corporate revolving credit facility. During the year ended December 31, 2024, we had total borrowings of $280.0 million and total repayments of $280.0 million under the revolving credit facility. Additionally, we had outstanding letters of credit issued in an aggregate amount of $8.7 million, leaving $591.3 million available for borrowing as of December 31, 2024. Our outstanding letters of credit as of December 31, 2024 are scheduled to expire beginning in April 2025. Our letters of credit obligations support performance bonds related to certain railcar orders. The revolving credit facility bears interest at a variable rate of SOFR plus (1) a benchmark adjustment of 10 basis points and (2) a facility margin of 1.50%, for an all-in interest rate of 6.13% as of December 31, 2024. A commitment fee accrues on the average daily unused portion of the revolving credit facility at the rate of 0.175% to 0.40% (0.20% as of December 31, 2024).
The revolving credit facility places certain restrictions on the Company and its subsidiaries, including, but not limited to, the ability to incur additional indebtedness and guarantee indebtedness; pay dividends or make other distributions or repurchase or redeem capital stock; prepay, redeem, or repurchase certain debt; make loans and investments; sell assets; incur liens on assets; enter into transactions with affiliates; and consolidate, merge, or liquidate. Additionally, the revolving credit facility requires the maintenance of ratios related to minimum interest coverage for the leasing and manufacturing operations and maximum leverage. As of December 31, 2024, we were in compliance with all such financial covenants. Borrowings under the credit facility are guaranteed by certain of our 100%-owned subsidiaries.
Senior Notes Due 2028 – In June 2023, we issued $400.0 million aggregate principal amount of 7.75% senior notes due July 2028. These notes were issued through a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and outside the United States to non-U.S. persons pursuant to Regulation S under the Securities Act. Interest on the Senior Notes due 2028 is payable semiannually commencing January 15, 2024.
In June 2024, we issued an additional $200.0 million aggregate principal amount of 7.75% senior notes due July 2028 (the "Additional Senior Notes"), which increased the aggregate principal amount from $400.0 million to $600.0 million. The Additional Senior Notes were issued at a price of 102.5% of the principal amount. Proceeds received from the issuance totaled approximately $209.0 million and included the premium described above and interest deemed to have accrued from January 15, 2024 through June 4, 2024. The Additional Senior Notes have identical terms and conditions (other than the original issue date, issue price, the first interest payment date and the first date from which interest will accrue) as the original issuance. Interest on the Additional Senior Notes is payable semiannually commencing July 15, 2024. We incurred $3.0 million in debt issuance costs from the issuance of the Additional Senior Notes, which will be amortized to interest expense over the term of the Senior Notes due 2028. Net proceeds received from the issuance, together with cash on hand, were used to repay $400.0 million of our Senior Notes due 2024, as described below, and to pay related fees, costs, premiums, and expenses in connection with the issuance.
The Senior Notes due 2028 rank senior to existing and future subordinated debt and rank equal to existing and future senior indebtedness, including our revolving credit facility. The Senior Notes due 2028 are subordinated to all our existing and future secured debt to the extent of the value of the collateral securing such indebtedness. The Senior Notes due 2028 contain covenants that limit our ability and/or certain subsidiaries' ability to create or permit to exist certain liens; enter into sale and leaseback transactions; and consolidate, merge, or transfer all or substantially all of our assets. Our Senior Notes due 2028 are fully and unconditionally and jointly and severally guaranteed by each of our domestic subsidiaries that is a guarantor under our revolving credit facility.
Senior Notes Due 2024 – In September 2014, we issued $400.0 million aggregate principal amount of 4.55% senior notes due October 2024. In June 2024, we redeemed in full $400.0 million aggregate principal amount of our 4.55% senior notes due 2024. Additionally, in connection with the redemption of the Senior Notes due 2024, during the year ended December 31, 2024, we recognized a loss on extinguishment of debt of $0.1 million, which related to the write-off of unamortized discount and debt issuance costs. These charges are reflected in the interest expense, net line of our Consolidated Statements of Operations for the year ended December 31, 2024. As a result of the redemption of the Senior Notes due 2024, we are no longer required to report supplemental guarantor financial information in this Annual Report on Form 10-K.

TILC Warehouse Loan Facility – TILC has historically maintained a warehouse loan facility to finance railcars owned by TILC. In March 2024, we entered into a new warehouse loan facility with a total commitment amount of $800.0 million, a revolving termination date of March 15, 2027, and a maturity date of March 15, 2028. This warehouse loan facility replaced the prior $1.0 billion warehouse loan facility. We incurred $3.9 million in debt issuance costs, which are recorded in other assets in our Consolidated Balance Sheets as of December 31, 2024, and are being amortized to interest expense over the facility term. During the year ended December 31, 2024, we had total borrowings of $1,064.6 million and total repayments of $1,009.3 million under the TILC warehouse loan facility. Of the remaining unused facility amount of $215.4 million, $167.9 million was available as of December 31, 2024 based on the amount of warehouse-eligible, unpledged equipment. The warehouse loan facility is a non-recourse obligation and is secured by a portfolio of railcars and operating leases, certain cash reserves, and other assets acquired and owned by the warehouse loan facility trust. The principal and interest of this indebtedness are paid from the cash flows of the underlying leases. Advances under the facility bear interest at one-month term SOFR plus a facility margin of 1.75%, for an all-in interest rate of 6.30% at December 31, 2024.

The all-in interest rate for the TRL VII Notes was 6.66% per annum. In connection with the redemption of the TRL VII Notes, during the year ended December 31, 2024, we recognized a loss on extinguishment of debt of $1.4 million, which included a $0.6 million early redemption premium and a write-off of $0.8 million in unamortized debt issuance costs.

In May 2024, TRL-2021 issued an aggregate principal amount of $432.4 million of its Series 2024-1 Class A Green Secured Railcar Equipment Notes (the "TRL-2024 Notes"). The TRL-2024 Notes, of which $424.5 million was outstanding as of December 31, 2024, bear interest at a fixed rate of 5.78%. The TRL-2024 Notes are payable monthly and have a stated final maturity date of May 19, 2054. We incurred $4.4 million in debt issuance costs, which will be amortized to interest expense through the anticipated repayment date of the TRL-2024 Notes. The TRL-2024 Notes are obligations of TRL-2021 and are non-recourse to Trinity. The obligations are secured by a portfolio of railcars and operating leases thereon, certain cash reserves, and other assets acquired and owned by TRL-2021. Net proceeds received from the railcars acquired in connection with the issuance of the TRL-2024 Notes were used to repay approximately $218.9 million of borrowings under TILC's warehouse loan facility; to redeem the outstanding debt of TRL VII, as described above; and for general corporate purposes.
TRL-2022 – In April 2022, Trinity Rail Leasing 2022 LLC, a Delaware limited liability company ("TRL-2022") and a limited purpose, indirect wholly-owned subsidiary of the Company owned through TILC, issued an aggregate principal amount of $244.8 million of its Series 2022-1 Class A Green Secured Railcar Equipment Notes (the "TRL-2022 Notes"). The TRL-2022 Notes, of which $223.7 million was outstanding as of December 31, 2024, bear interest at a fixed rate of 4.55%, are payable monthly, and have a stated final maturity date of May 20, 2052. The TRL-2022 Notes are obligations of TRL-2022 and are non-recourse to Trinity. The obligations are secured by a portfolio of railcars and operating leases thereon, certain cash reserves, and other assets acquired and owned by TRL-2022.
TRL-2023 Term Loan – In June 2023, TRL-2023 entered into a $340.0 million term loan agreement. The TRL-2023 term loan was established to finance railcars and related operating leases thereon purchased by TRL-2023 from TILC and TILC's warehouse loan facility. The TRL-2023 term loan bears interest at a variable rate of daily simple SOFR plus (1) a benchmark adjustment of 10 basis points and (2) a facility margin of 1.80%, for an all-in interest rate of 6.36% as of December 31, 2024. The TRL-2023 term loan has a stated maturity date of June 12, 2028. The TRL-2023 term loan is an obligation of TRL-2023 and is non-recourse to Trinity. The obligation is secured by a portfolio of railcars and operating leases thereon, certain cash reserves, and other assets acquired and owned by TRL-2023.
Other equipment financing – In December 2023, TILC sold to a third party, and subsequently leased back, certain railcars for total proceeds of $52.3 million. The transaction did not qualify as a sale-leaseback and is being accounted for as a financing transaction. Accordingly, no gain or loss was recorded in connection with this transaction, and the sold assets remain within property, plant, and equipment, net in our Consolidated Balance Sheets and will continue to be depreciated over their remaining useful lives for the duration of the lease. A financing liability equal to the amount of consideration received from the buyer-lessor was recorded within debt in our Consolidated Balance Sheets. A portion of the future lease payments that we make to the buyer-lessor will reduce the financing liability and the remainder will be recorded as interest expense. As of December 31, 2024, the carrying value of the financing liability was $50.0 million.

During the year ended December 31, 2022, we recognized a loss on extinguishment of debt of $1.5 million, which related to the write-off of unamortized debt issuance costs in connection with the repayment of TRIP Railcar Co. LLC's outstanding term loan agreement. These charges are reflected in the interest expense, net line of our Consolidated Statements of Operations for the year ended December 31, 2022.
Triumph Rail and Tribute Rail are wholly-owned subsidiaries of TRIP Holdings, and TRP-2021 is a wholly-owned subsidiary of RIV 2013. TRIP Holdings and RIV 2013 are partially-owned subsidiaries of the Company, through its wholly-owned subsidiary, TILC. Our ownership interests in TRIP Holdings and RIV 2013 are 42.6% and 30.5%, respectively. See Note 5 for further information.
Scheduled Repayments of Debt
Each of our secured railcar equipment notes generally has an anticipated repayment date and a stated final maturity date. While the stated final maturity dates of each of these notes can be up to 30 years after the respective issuance dates, the cash flows from the encumbered assets of each of these notes will be applied, pursuant to the payment priorities of their respective indentures, so as to amortize their respective notes to achieve monthly targeted principal balances. If the cash flow assumptions used in determining the targeted balances are met, it is anticipated that the notes will be repaid well in advance of their stated final maturity date; the repayments reflected in the table below are based on the earlier anticipated repayment dates rather than the stated final maturity dates. There can be no assurance, however, that such cash flow assumptions will be realized. If these notes are not repaid by the anticipated repayment date, the respective interest rates on these notes would increase from the fixed rates stated above.
The remaining principal payments under existing debt agreements as of December 31, 2024 based on the anticipated repayment dates are as follows:

During the year ended December 31, 2023, one of our partially-owned subsidiaries released residual tax effects that had previously been recorded in AOCI. This deferred tax benefit was originally recorded before the partially-owned subsidiary was treated as a flow-through entity, remaining in AOCI until the underlying book-to-tax difference no longer existed, which occurred during the year ended December 31, 2023. As a result, we recorded an $11.9 million income tax benefit in our Consolidated Statements of Operations during the year ended December 31, 2023.
We remeasure our state deferred tax liability on a regular basis based upon our estimate of our state tax apportionment as applied to enacted state tax rates. We also adjust our deferred balances based upon changes in tax laws and rates during the period in which those laws and rates are enacted, as well as adjusting for acquisition and disposition activity of businesses. As a result of our changes in apportionment, tax law changes, and business additions, we recorded a non-cash, deferred tax expense of $0.9 million, a benefit of $10.6 million, and an expense of $0.7 million during the years ended December 31, 2024, 2023, and 2022, respectively.
The tax provisions for the years ended December 31, 2024, 2023, and 2022 also reflect a benefit for a net adjustment to our valuation allowances of $1.8 million, $3.2 million, and $1.1 million, respectively, primarily for deferred tax assets in Mexico, state tax loss carryforwards, state reserves, and federal tax credits.
Income (loss) from continuing operations before income taxes for the years ended December 31, 2024, 2023, and 2022 was $212.9 million, $137.2 million, and $127.1 million, respectively, for U.S. operations, and $8.9 million, $11.8 million, and $(0.6) million, respectively, for foreign operations.
Deferred income taxes represent the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The components of deferred tax liabilities and assets are as follows:

At December 31, 2024, we had $19.0 million of tax-effected state loss carryforwards and $11.7 million of net federal and state credits remaining. We have established valuation allowances for federal, state, and foreign tax operating losses and credits that we have estimated may not be realizable.
Taxing authority examinations
Our federal tax return years through 2021 are closed under statute and the years 2022-2024 remain open. We have state tax returns that are under audit in the normal course of business, and the statutes of limitations for our Mexican subsidiaries' tax returns remain open for audit for 2019 and forward. We believe we are appropriately reserved for any potential matters.
Unrecognized tax benefits
The change in unrecognized tax benefits was as follows:

Settlements— — — 
Expiration of statute of limitations(0.1)— (1.3)
Ending balance$0.9 $1.0 $3.8 
The total amount of unrecognized tax benefits, including interest and penalties, at December 31, 2024 and 2023, that would affect our effective tax rate if recognized, was $2.6 million and $2.6 million, respectively. The additions for tax positions in the prior years are due to foreign positions of an acquired subsidiary that was recorded as part of our purchase accounting. The expiration of statute of limitations relates to a state tax position for which the statute of limitations has lapsed.
The Company accounts for interest expense and penalties related to income tax issues as income tax expense. Accordingly, interest expense and penalties associated with an uncertain tax position are included in the income tax provision. The total amount of accrued interest and penalties from continuing operations as of December 31, 2024 and 2023 was $2.4 million and $2.3 million, respectively. Income tax expense (benefit) for the years ended December 31, 2024, 2023, and 2022 included an increase of $0.1 million, an increase of $0.1 million, and a decrease of $0.8 million, respectively, with regard to interest expense and penalties related to uncertain tax positions.
Pillar Two
During the year ended December 31, 2024, Canada enacted a 15% minimum tax on all companies that operate in its jurisdiction, consistent with one or more Organization for Economic Co-operation and Development Global Anti-Base Erosion Model Rules ("Pillar Two"). We do not expect that Canada’s enactment of Pillar Two will have a material impact to our income tax expense. Pillar Two legislation has not been enacted in the other jurisdictions in which we operate, and we will continue to monitor our potential exposure as more jurisdictions adopt these provisions.

Amounts recognized in other comprehensive income related to actuarial gains and the amortization of actuarial gains or losses during the years ended December 31, 2024, 2023, and 2022 were not significant in relation to the Consolidated Financial Statements. At December 31, 2024, AOCI included unrecognized actuarial losses related to our SERP of $2.3 million ($1.2 million net of related income taxes). Actuarial losses included in AOCI and expected to be recognized in net periodic pension cost for the year ended December 31, 2025 are $0.1 million ($0.1 million, net of related income taxes).
Funding of Defined Contribution Plans
The Company's 401(k) plan utilizes a qualified automatic contribution arrangement safe harbor plan structure. The matching structure provides for a dollar-for-dollar Company match on up to 6% of participants' eligible compensation, subject to a two-year cliff vesting period. Employer contributions to the 401(k) plan and the Trinity Industries, Inc. Deferred Compensation Plan for the year ending December 31, 2025 are expected to be $12.3 million, compared to $11.8 million contributed during 2024.

In May 2013, one of our partially-owned leasing subsidiaries, TRIP Holdings, was converted to a partnership for income tax purposes. At the time of the conversion, TRIP Holdings had deferred tax assets associated with certain terminated interest rate hedges that were initially recognized as a component of AOCI. As TRIP Holdings was no longer a taxable entity following the conversion, these deferred tax assets were removed during the year ended December 31, 2013, with a corresponding charge to income tax expense in the Consolidated Statements of Operations, leaving residual tax effects in AOCI. These residual tax effects are released when the item giving rise to the tax effect is disposed of, liquidated, or terminated. Pursuant to our election of the portfolio approach, we released the residual tax effects when all of the interest rate swap balances were fully amortized, which occurred during the first quarter of 2023. Consequently, during the year ended December 31, 2023, we recorded an income tax benefit of $13.2 million to TRIP Holdings, reflecting the reclassification of the residual tax effects previously recorded in AOCI. The controlling interest portion of this income tax benefit was $4.4 million.
See Note 3 for information on the reclassification of amounts in AOCI into earnings. Reclassifications of unrealized before-tax gains and losses on derivative financial instruments are included in interest expense, net for our interest rate hedges and in cost of revenues for our foreign currency hedges in our Consolidated Statements of Operations. Reclassifications of before-tax net actuarial gains/(losses) of defined benefit plans are included in other, net (income) expense in our Consolidated Statements of Operations.

Share Repurchase Authorization
In December 2022, our Board of Directors authorized a share repurchase program effective December 9, 2022 with no expiration. The share repurchase program authorizes the Company to repurchase up to $250.0 million of its common stock. During the year ended December 31, 2024, share repurchases totaled 0.6 million shares, at a cost of approximately $21.0 million, resulting in a remaining authorization to repurchase up to $229.0 million of our common stock under the share repurchase program as of December 31, 2024. Certain shares of stock repurchased during December 2024, totaling $0.3 million, were cash settled in January 2025 in accordance with normal settlement practices. There were no shares repurchased under this share repurchase program during the year ended December 31, 2023.
Previous Share Repurchase Authorization
In September 2021, our Board of Directors authorized a share repurchase program effective September 9, 2021 through December 31, 2022. The share repurchase program authorized the Company to repurchase up to $250.0 million of its common stock. In December 2021, we entered into an accelerated share repurchase agreement (the "ASR") to repurchase $125.0 million of our common stock. Approximately 3.3 million shares totaling $100.0 million that were repurchased as part of the ASR on December 31, 2021 were delivered to the Company in January 2022 in accordance with normal settlement practices, representing approximately 80% of the total notional value of the ASR. The ASR was completed in April 2022. During the year ended December 31, 2022, share repurchases totaled 2.8 million shares, at a cost of approximately $76.8 million. Share repurchases during the year ended December 31, 2022 included 0.8 million shares, at a cost of $25.0 million, representing the final settlement of the ASR, which was funded in December 2021 but a portion of which remained outstanding as of December 31, 2021. Our Board of Directors terminated this share repurchase program effective December 8, 2022, and the remaining authorization of $21.3 million under this program expired unused.

Stock-Based Compensation
Stock Award Plans
Our Fifth Amended and Restated Stock Option and Incentive Plan (the "Plan”) provides for awarding 22,050,000 (adjusted for stock splits) shares of common stock plus (i) shares covered by forfeited, expired, and canceled options granted under prior plans; and (ii) shares tendered as full or partial payment for the purchase price of an award or to satisfy tax withholding obligations. At December 31, 2024, a total of 2,978,308 shares were available for issuance. The Plan provides for the granting of nonqualified and incentive stock options having maximum ten-year terms to purchase common stock at its market value on the award date; stock appreciation rights based on common stock fair market values with settlement in common stock or cash; restricted stock awards; restricted stock units; and performance awards with settlement in common stock or cash on achievement of specific business objectives. Our stock options have contractual terms of ten years and become exercisable over a three-year period.
Stock-Based Compensation Expense
The cost of employee services received in exchange for awards of equity instruments is referred to as stock-based compensation and is recognized over the applicable vesting periods based on the grant date fair-value of those awards. Stock-based compensation expense totaled $23.6 million, $22.7 million, and $22.5 million for the years ended December 31, 2024, 2023, and 2022, respectively.
The income tax benefit related to stock-based compensation expense was $6.8 million, $2.8 million, and $2.6 million for the years ended December 31, 2024, 2023, and 2022, respectively.

At December 31, 2024, there was no unrecognized compensation expense related to stock options. The weighted average exercise price of stock options outstanding as of December 31, 2024 was $21.61. There were no options exercised during the years ended December 31, 2024, 2023, and 2022.
Restricted Stock Units
Expense related to restricted stock units ("RSUs") issued to eligible employees under the Plan is recognized over the vesting period, generally between three years and four years. Beginning in 2020, certain RSU grants provide for full vesting when the award recipients retire having reached 60 years of age and having provided at least ten years of service to the Company, provided that the awards remain outstanding for a period of six months from the date of grant. The expense for these awards is recognized over the applicable service period for each of the eligible award recipients. Expense related to RSUs granted to non-employee directors under the Plan is recognized on a straight-line basis over the vesting period, generally one year. The fair value of RSUs granted is based on the Company's closing stock price on the date of grant. Forfeitures are recognized as a reduction to expense in the period in which they occur.

At December 31, 2024, unrecognized compensation expense related to RSUs totaled $15.0 million, which will be recognized over a weighted average period of 1.5 years.
Performance Units
Performance units are granted to employees based upon a target level; however, depending upon the achievement of certain specified goals during the performance period, performance units may be adjusted to a level ranging between 0% and 200% of the target level. The performance units vest upon certification by the Human Resources Committee of the Board of Directors of the achievement of the specified performance goals. Expense related to performance units is recognized on a straight-line basis from their award date to the end of the performance period, generally three years. For the performance units granted for which the payout is based on relative total shareholder return, the fair value was estimated at the date of grant using a Monte Carlo simulation with assumptions that reflect market conditions at the date of grant, including stock price, risk-free interest rate, expected term, expected volatility, and dividend yield. For the performance units granted for which the payout is based on return on equity, the fair value is based on the Company's closing stock price on the date of grant, adjusted to exclude the cumulative value of dividends over the three-year vesting period as these units do not earn dividend equivalents. Forfeitures are recognized as a reduction to expense in the period in which they occur.

Restricted Stock Awards
Expense related to restricted stock awards ("RSAs") granted to non-employee directors under the Plan is recognized on a straight-line basis over the vesting period, generally one year. Certain RSAs vest in their entirety upon an employee's retirement from the Company, taking into consideration the employee's age and years of service to the Company, as defined more specifically in our benefit plans. The fair value of RSAs granted is based on the Company's closing stock price on the date of grant. Forfeitures are recognized as a reduction to expense in the period in which they occur.

Earnings Per Share
Note 14. Earnings Per Common Share
Basic net income attributable to Trinity Industries, Inc. per common share ("EPS") is computed by dividing net income attributable to Trinity by the weighted average number of basic common shares outstanding for the period. Except when the effect would be antidilutive, the calculation of diluted EPS includes the net impact of potentially dilutive common shares. The Company has certain unvested RSAs that participate in dividends on a nonforfeitable basis and are therefore considered to be participating securities. Consequently, diluted net income attributable to Trinity Industries, Inc. per common share is calculated under both the two-class method and the treasury stock method, and the more dilutive of the two calculations is presented.
The following table sets forth the computation of basic and diluted net income attributable to Trinity Industries, Inc.:

East Palestine, OH Train Derailment
On February 3, 2023, a Norfolk Southern Railway freight train derailed 38 railcars in East Palestine, Ohio. In March 2023, the State of Ohio and the United States Environmental Protection Agency filed lawsuits against Norfolk Southern Railway Company and Norfolk Southern Corporation (“Norfolk Southern”), which were consolidated in the United States District Court for the Northern District of Ohio, Eastern Division in a civil action styled The State of Ohio, ex rel., Dave Yost, Ohio Attorney General, and the United States of America, Plaintiffs v. Norfolk Southern Railway Company and Norfolk Southern Corporation, Defendants, Civil Action No. 4:23-cv-00517. On June 30, 2023, Norfolk Southern filed a third-party complaint against the Company’s wholly-owned subsidiary, TILC, and certain other third-party defendants. Norfolk Southern asserted third-party claims against TILC for recovery of response costs, contribution, and declaratory relief under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA"); negligence; and equitable contribution. TILC was the owner of one tank car cited in this action, which was leased to a third party, who is also a third-party defendant in the litigation. On March 6, 2024, the trial court granted TILC’s motion to dismiss Norfolk Southern’s Third-Party Complaint and entered an order dismissing Norfolk Southern’s complaint against TILC. On March 26, 2024, Norfolk Southern filed a Motion for Entry of Partial Final Judgment, which remains pending.
In April 2023, multiple putative class action lawsuits filed against Norfolk Southern were consolidated in the United States District Court for the Northern District of Ohio, Eastern Division in a civil action styled In re: East Palestine Train Derailment, Civil Action No. 4:23-CV-00242 ("Consolidated Class Action"). On July 25, 2023, Norfolk Southern filed a third-party complaint against the Company’s wholly-owned subsidiary, TILC, and certain other third-party defendants. Norfolk Southern asserted third-party claims against TILC for negligence, joint and several liability, and contribution. On August 14, 2023, plaintiffs filed a First Amended Master Consolidated Class Action Complaint and Jury Demand (“First Amended Complaint”) asserting direct claims for negligence, gross negligence, and medical monitoring against Oxy Vinyls LP, GATX Corporation, General American Marks Company, and TILC ("Railcar Defendants"). TILC was the owner of one tank car cited in this action, which was leased to a third party, who is also a third-party defendant in the litigation. On April 9, 2024, plaintiffs and Norfolk Southern announced a settlement in principle of plaintiffs’ claims against Norfolk Southern and the Railcar Defendants. Norfolk Southern preserved its third-party claims against the Railcar Defendants. On May 22, 2024, the parties filed a joint motion to dismiss, with prejudice, Norfolk Southern’s third-party claims against TILC (the “Dismissal Motion”). On June 3, 2024, the court entered an order granting the Dismissal Motion (the “Dismissal Order”). The Dismissal Order dismisses, with prejudice, all of Norfolk Southern’s claims against TILC, including claims for negligence and contribution. On September 27, 2024, the district court entered an order approving the settlement of plaintiffs’ claims against Norfolk Southern and the Railcar Defendants. Certain individual class members have filed notices of appeal concerning the order approving the settlement. The appeals remain pending.
On December 8, 2023, a lawsuit was filed against TILC titled Ambridge Area School District et al. v. Norfolk Southern Corporation et al., Case No. 2:23-cv-01530-CB, in the United States District Court for the Western District of Pennsylvania. Plaintiffs in this putative class action lawsuit assert claims against Norfolk Southern Corporation, Norfolk Southern Railway Company, Oxy Vinyls, LP, GATX Corporation, General American Marks Company, and TILC for negligence, negligence per se, strict liability, public and private nuisance, future health monitoring, trespass, and punitive damages. On February 23, 2024, TILC filed a motion to dismiss plaintiffs’ amended complaint, which remains pending. TILC was the owner of one tank car cited in this action, which was leased to a third party, who is also a defendant in the litigation.
On January 31, 2025, a lawsuit was filed by more than 700 current and former residents and businesses in areas near East Palestine, Ohio against more than 50 defendants, including Norfolk Southern, Oxy Vinyls LP, GATX Corporation, General American Marks Company, TILC, certain governmental entities, and various corporate defendants, asserting various claims arising from the February 3, 2023 derailment. The case is styled Josh Hickman, et al. v. Norfolk Southern Railway Company, et al., Case No. TC25-13854798, in the Court of Common Pleas, Franklin County, Ohio. Plaintiffs’ lawsuit asserts claims for negligence, nuisance and nuisance per se, strict liability, trespass, punitive damages, loss of consortium, wrongful death, survivorship, civil conspiracy, and Medicaid subrogation. Not all plaintiffs in this action are asserting claims against TILC in light of the pending settlement and associated releases in the Consolidated Class Action. TILC was the owner of one tank car cited in this action, which was leased to a third party, who is also a defendant in the litigation.
On February 3, 2025, a lawsuit was filed by 20 current and former residents of areas near East Palestine, Ohio against more than 50 defendants, including Norfolk Southern, Oxy Vinyls LP, GATX Corporation, General American Marks Company, TILC, certain governmental entities, and various corporate defendants asserting various claims arising from the February 3, 2023 derailment. The case is styled Gregory Taylor, et al. v. Norfolk Southern Railway Company, et al., Case No. TC25-13870158, in the Court of Common Pleas, Franklin County, Ohio. Plaintiffs’ lawsuit asserts claims for negligence, nuisance and nuisance per se, strict liability, trespass, punitive damages, loss of consortium, civil conspiracy, and Medicaid subrogation. Not all plaintiffs are asserting claims against TILC in light of the pending settlement and associated releases in the Consolidated Class Action. TILC was the owner of one tank car cited in this action, which was leased to a third party, who is also a defendant in the litigation.
On February 3, 2025, a lawsuit was filed by 28 current and former residents or businesses of areas near East Palestine, Ohio against more than 15 corporate defendants, including Norfolk Southern, Oxy Vinyls LP, GATX Corporation, General American Marks Company, and TILC asserting various claims arising from the February 3, 2023 derailment. The case is styled Richard Tsai, et al. v. Norfolk Southern Corporation, et al., Case No. TC25-3395394, in the Court of Common Pleas, Cuyahoga County, Ohio. Plaintiffs’ lawsuit asserts claims for negligence, negligence per se, gross negligence, recklessness, strict liability, private nuisance, public nuisance, statutory nuisance under Pennsylvania and Ohio law, negligent infliction of emotional distress, intentional and/or reckless infliction of emotional distress, trespass, trespass to chattels, medical monitoring, loss of consortium, wrongful death, survivorship, and punitive damages, as well as an additional spoliation claim against Norfolk Southern. On February 3, 2025, these plaintiffs filed similar actions in Pennsylvania, styled Richard Tsai, et al. v. Norfolk Southern Corporation, et al., Case Nos. 250200415 and 250200416, in the Court of Common Pleas, Philadelphia County, Pennsylvania. TILC was the owner of one tank car cited in these actions, which was leased to a third party, who is also a defendant in these matters.
The Company believes it has substantial defenses and intends to vigorously defend itself against all allegations in the third-party and direct claims asserted against TILC. The Company or its subsidiaries could be named in similar litigation involving other plaintiffs, but the ultimate number of claims and the jurisdiction(s) in which such claims, if any, may be filed may vary. We do not believe at this time that a loss is probable in these matters, nor can a range of possible losses be determined. Accordingly, no accrual or range of loss has been included in the accompanying consolidated financial statements. The Company maintains liability insurance coverage and commercial contractual indemnity rights to protect the Company’s assets from losses arising from these types of litigation claims.
Highway Products Litigation
Pursuant to the purchase and sale agreement related to the sale of THP, the Company agreed to indemnify Rush Hour for certain liabilities related to the highway products business, including those liabilities resulting from or arising out of (a) the proceedings set forth under “State actions” below and (b) any other proceedings to the extent resulting from or arising out of ET Plus systems or specified ET Plus component parts that are both (i) manufactured prior to December 31, 2021, and (ii) sold in the United States on or prior to April 30, 2022, or related warranty obligations with respect thereto.
State actions
Mr. Joshua Harman filed a state qui tam action currently pending pursuant to the Virginia Fraud Against Taxpayers Act ("VFATA") (Commonwealth of Virginia ex rel. Joshua M. Harman v. Trinity Industries, Inc. and Trinity Highway Products, LLC, Case No. CL13-698, in the Circuit Court, Richmond, Virginia). Mr. Harman alleged the Company violated the VFATA pertaining to sales of the ET Plus, and he is seeking damages, civil penalties, attorneys’ fees, costs, and interest. The Commonwealth of Virginia Attorney General has intervened in the Virginia matter. On February 7, 2024, the trial court granted the Company's motion for summary judgment. On July 26, 2024, Mr. Harman filed a Notice of Appeal of the trial court’s final judgment and all adverse rulings, including the denial of Mr. Harman’s and the Commonwealth of Virginia’s motion for reconsideration. Mr. Harman’s appeal remains pending.
In a similar New Jersey state qui tam action (State of New Jersey ex rel. Joshua M. Harman v. Trinity Industries, Inc. and Trinity Highway Products, LLC, Case No.L-1344-14, in the Superior Court of New Jersey Law Division: Mercer County) that was previously dismissed by the trial court, Mr. Harman sought leave to file an amended complaint pursuant to the New Jersey False Claims Act. On February 16, 2022, the trial court denied Mr. Harman’s motion. On August 9, 2022, Mr. Harman appealed the trial court's order denying Mr. Harman's motion for leave to file an amended complaint. On December 27, 2024, the appellate court affirmed the trial court’s order denying Mr. Harman leave to file an amended complaint. Mr. Harman’s deadline to file a Notice of Petition for Certification to the New Jersey Supreme Court was January 16, 2025, and no such notice was filed.
The Company believes that it has substantial defenses in these matters and intends to vigorously defend against all allegations. Based on information currently available to the Company, we currently do not believe that a loss is probable in the state qui tam actions described above, therefore no accrual has been included in the accompanying Consolidated Financial Statements. Because of the complexity of these actions, as well as the current status of certain of these actions, we are not able to estimate a range of possible losses with respect to any one or more of these actions. While the financial impacts of these state actions are currently unknown, they could be material.
Product liability cases
The Company is currently defending product liability lawsuits that are alleged to involve the ET Plus as well as other products manufactured by THP. These cases are diverse in light of the randomness of collisions in general and the fact that each accident involving a roadside device, such as an end terminal, or any other fixed object along the highway, has its own unique facts and circumstances. The Company carries general liability insurance to mitigate the impact of adverse judgment exposures in these product liability cases. To the extent that the Company believes that a loss is probable with respect to these product liability cases, the accrual for such losses is included in the amounts described below under "Other matters".
Other Matters
The Company is involved in claims and lawsuits incidental to our business arising from various matters, including product warranty, personal injury, environmental issues, workplace laws, and various governmental regulations. The Company evaluates its exposure to such claims and suits periodically and establishes accruals for these contingencies when a range of loss can be reasonably estimated. The range of reasonably possible losses for such matters is $7.5 million to $18.9 million. This range includes any amounts related to the matters described above in the section titled “Highway products litigation." At December 31, 2024, total accruals of $8.9 million, including environmental and workplace matters described below, are included in accrued liabilities in the accompanying Consolidated Balance Sheets. The Company believes any additional liability would not be material to its financial position or results of operations.
Trinity is subject to remedial orders and federal, state, local, and foreign laws and regulations relating to the environment and the workplace. The Company has reserved $1.2 million to cover our probable and estimable liabilities with respect to the investigations, assessments, and remedial responses to such matters, taking into account currently available information and our contractual rights to indemnification and recourse to third parties. However, estimates of liability arising from future proceedings, assessments, or remediation are inherently imprecise. Accordingly, there can be no assurance that we will not become involved in future litigation or other proceedings involving the environment and the workplace or, if we are found to be responsible or liable in any such litigation or proceeding, that such costs would not be material to the Company. We believe that we are currently in substantial compliance with environmental and workplace laws and regulations.
Loss Events in Cartersville, Georgia
We experienced two separate loss events at the Company's facility in Cartersville, Georgia. With each of these events, we incurred costs related to cleanup and damage remediation activities in order for the facility to resume operations. We believe our insurance coverage is sufficient to cover property damage costs related to these events. Any property damage insurance proceeds received in excess of the net book value of property lost and related cleanup costs are accounted for as a gain, in accordance with ASC 450-30, Gain Contingencies. Additionally, the Company may be entitled to business interruption proceeds related to these events. We record these recoveries once settlements have been reached with the insurance company.
Fire
In January 2024, a fire damaged a portion of our Cartersville, Georgia facility. To date, we have received total advanced payments from insurance of approximately $5.4 million, which includes $1.7 million for reimbursement of cleanup and damage remediation activities and the collection of a $1.0 million insurance receivable. As of December 31, 2024, we have utilized $2.7 million of the advanced payments from insurance towards new capital expenditures in support of the reconstruction efforts. During the year ended December 31, 2024, we recorded gains of $2.7 million for property damage insurance recoveries in excess of the net book value of assets destroyed, which is included in the gains on dispositions of other property line in our Consolidated Statements of Operations.
Tornado
In March 2021, a tornado damaged our Cartersville, Georgia facility. During the years ended December 31, 2023 and 2022, we recorded gains of $6.3 million and $7.5 million, respectively, for property damage insurance recoveries in excess of the net book value of assets destroyed, which is included in the gains on dispositions of other property line in our Consolidated Statements of Operations.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
Assessing, Identifying, and Managing Material Risks
Trinity’s IRM program is aligned to the National Institute of Science and Technology (“NIST”) Cybersecurity Framework (“CSF”) and conducts maturity assessments against the NIST CSF on a quarterly basis. Our IRM program encompasses the full lifecycle of information risk, from creation through disposition, and is guided by policies, processes, standards, and procedures in vulnerability management, incident response, information governance, risk management, and security awareness. Additionally, Trinity exercises a variety of testing approaches to assess the state of systems and personnel, including annual penetration testing by independent third parties, ad hoc penetration testing by internal personnel, and tabletop exercises for executive and senior leadership, information technology, IRM, and legal employees. Trinity also maintains an incident response relationship with an industry-leading provider to ensure resource availability if a significant event were to occur.
As cybersecurity touches all employees, we include formal training on cybersecurity in the annually required Code of Business Conduct training. The training focuses on awareness of cybersecurity risks and requirements. For targeted groups, we conduct phishing email response checks.
Cybersecurity Risk Management Processes Integrated [Text Block]
Integration Into Overall Risk Management
Cybersecurity risk management is integrated into our broader enterprise risk management framework to promote a culture of cybersecurity awareness. This integration ensures that cybersecurity considerations are an integral part of our decision-making processes throughout Trinity. Our IRM team works closely with our information technology department to continuously evaluate and address cybersecurity risks in alignment with our business objectives and operational needs. Cybersecurity risks are assessed by Trinity’s IRM team, and the risk assessment is aligned with business-level processes and is consistent with Trinity’s standard enterprise risk management methods and thresholds. Our IRM organization regularly consumes a variety of threat intelligence and information security news sources to inform and align risk management decisions to current threats and threat landscapes.

Significant Accounting Policies [Text Block] Summary of Significant Accounting Policies
Principles of Consolidation
The financial statements of Trinity Industries, Inc. and Subsidiaries (“Trinity,” “Company,” “we,” “our,” or "us") include the accounts of our wholly-owned subsidiaries and our partially-owned subsidiaries, TRIP Rail Holdings LLC ("TRIP Holdings"), RIV 2013 Rail Holdings LLC ("RIV 2013"), and Trinity Global Ventures Limited ("Trinity Global Ventures"), in which we have a controlling interest. All significant intercompany accounts and transactions have been eliminated. Certain prior year balances have been reclassified to conform to the 2024 presentation.
Our Reportable Segments
Effective January 1, 2024, the Company modified its organizational structure to better leverage our maintenance services capabilities to support lease fleet optimization and to grow our services and parts businesses. The new structure resulted in a change to our reportable segments beginning in 2024. In connection with this organizational update, we aligned the maintenance services business, which was previously reported in the Rail Products Group, to now be presented within our leasing business. This change aligns with the way in which our Chief Operating Decision Maker ("CODM") assesses performance and allocates resources. Consequently, beginning January 1, 2024, we report our operating results in two reportable segments: (1) the Railcar Leasing and Services Group, formerly the Railcar Leasing and Management Services Group, and (2) the Rail Products Group. These changes had no impact to our previously reported consolidated results of operations, financial position, or cash flows. All prior period segment results set forth herein have been recast to reflect these changes and present results on a comparable basis.
Revenue Recognition
Revenue associated with our railcar lease contracts is recognized in accordance with Accounting Standards Codification ("ASC") 842, Leases. Revenue associated with our railcar manufacturing, maintenance services, digital and logistics services businesses, and certain servicing, maintenance, and management agreements is recognized in accordance with ASC 606, Revenue from Contracts with Customers.
Revenue is measured based on the allocation of the transaction price in a contract to satisfied performance obligations. The transaction price does not include any amounts collected on behalf of third parties. We recognize revenue when we satisfy a performance obligation by transferring control over a product or service to a customer. For all contracts with customers, we evaluate whether we are the principal (i.e., report revenues on a gross basis) or agent (i.e., report revenues on a net basis). Generally, we are the principal in our contracts with customers and report revenues on a gross basis as we control the product or service before it is transferred to a customer. We act as an agent for a small number of service contracts and report those revenues on a net basis as we do not control the services before they are provided to the customer. Payments for our products and services are generally due within normal commercial terms.
The following is a description of principal activities from which we generate our revenue, separated by reportable segments. See Note 4 for a further discussion regarding our reportable segments.
Railcar Leasing and Services Group
In our Railcar Leasing and Services Group ("Leasing Group"), revenue from rentals and operating leases, including contracts that contain non-level fixed lease payments, is recognized monthly on a straight-line basis. Leases not classified as operating leases are generally considered sales-type leases as a result of an option to purchase.
We review our operating lease receivables for collectibility on a regular basis, taking into consideration changes in factors such as the lessee’s payment history, the financial condition of the lessee, and business and economic conditions in the industry in which the lessee operates. In the event that the collectibility of a receivable with respect to any lessee is no longer probable, we derecognize the revenue and related receivable and recognize future revenue only when the lessee makes a rental payment. Contingent rents are recognized when the contingency is resolved.
Selling profit or loss associated with sales-type leases is recognized upon lease commencement, and a net investment in the sales-type lease is recorded in the Consolidated Balance Sheets. Interest income related to sales-type leases is recognized over the lease term using the effective interest method. See "Lease Accounting" below for additional information regarding sales-type leases as of December 31, 2024 and 2023.
We report all sales of railcars from the lease fleet and selling profit or loss associated with sales-type leases as a net gain or loss from the disposal of a long-term asset in accordance with ASC 610-20, Gains and losses from the derecognition of non-financial assets. These sales are presented in the Lease portfolio sales line in our Consolidated Statements of Operations.
Our maintenance services business is primarily dedicated to servicing our lease fleet. Revenues related to maintenance services performed on Company-owned railcars under full-service lease agreements are eliminated within the Railcar Leasing and Services Group. Services that are not included in the full-service lease agreement, such as repairs of railcar damage or other customer-specific requirements, as well as maintenance and repair activities on railcars owned by third parties, including our investor-owned fleet, are reflected in the Leasing Group's revenues and are not eliminated in consolidation.
Within maintenance services, revenue is recognized over time as repair and maintenance projects are completed, using an input approach based on the costs incurred relative to the total estimated costs of performing the project. We recorded contract assets of $9.6 million and $8.8 million as of December 31, 2024 and December 31, 2023, respectively, related to unbilled revenues recognized on repair and maintenance activities that have been performed, but for which the entire project has not yet been completed, and the railcar has not yet been shipped to the customer. These contract assets are included within the Receivables, net of allowance line in our Consolidated Balance Sheets.
In connection with an acquisition that occurred during the first quarter of 2023, we evaluated whether we are acting as a principal or an agent for certain logistics services provided to a small number of customers. During the fourth quarter of 2023, we concluded that we act as an agent in these transactions as we do not control the services before they are provided to the customer, and as a result, revenues that were previously recognized on a gross basis should be recognized on a net basis. We elected to effect this accounting change on a prospective basis as it was not quantitatively or qualitatively material to our consolidated financial statements, and beginning in the fourth quarter of 2023, revenues associated with these services are now recognized on a net basis. The accounting change had no effect on the Company's previously reported operating profit, net income, earnings per share, Consolidated Balance Sheets, or Consolidated Statements of Cash Flows.
Rail Products Group
Our railcar manufacturing business recognizes revenue related to new railcars at a point in time when the customer has submitted its certificate of acceptance and legal title of the railcar has passed to the customer. Certain contracts for the sales of railcars include price adjustments based on changes to input costs; this amount represents variable consideration for which we are generally unable to estimate the final consideration until the railcar is delivered.
Revenue related to sustainable railcar conversions is recognized over time as sustainable railcar conversions are completed, using an input approach based on the costs incurred relative to the total estimated costs of performing the project. Revenue related to certain support services is recognized over time based on our stand-ready obligation to provide such services. We recorded contract assets of $3.4 million and $12.6 million as of December 31, 2024 and 2023, respectively. These contract assets are included within the Receivables, net of allowance line in our Consolidated Balance Sheets.
We account for shipping and handling costs as activities to fulfill the promise to transfer the good; as such, these fees are recorded in revenue. The fees and costs of shipping and handling activities are accrued when the related performance obligation has been satisfied.
Unsatisfied Performance Obligations
The following table includes estimated revenue expected to be recognized in future periods related to performance obligations that are unsatisfied or partially satisfied as of December 31, 2024 and the percentage of the outstanding performance obligations as of December 31, 2024 expected to be delivered during 2025:

The remainder of the unsatisfied performance obligations for the Rail Products Group is expected to be delivered through 2028. The orders in the Rail Products Group's backlog from the Leasing Group are fully supported by lease commitments with external customers. The final amount of backlog attributable to the Leasing Group may vary by the time of delivery as customers may elect to change their procurement decision.
Unsatisfied performance obligations for the Railcar Leasing and Services Group are related to servicing, maintenance, and management agreements and are expected to be performed through 2029.
Lease Accounting
Lessee
We are the lessee of operating leases predominantly for office buildings and railcars, as well as manufacturing equipment and office equipment. Our operating leases have remaining lease terms ranging from one year to twelve years, some of which include options to extend for up to five years, and some of which include options to terminate within one year. As of December 31, 2024, we had no material finance leases in which we were the lessee. Certain of our operating leases include lease incentives, which reduce the right-of-use asset and are recognized on a straight-line basis over the lease term.

Lessor
Our Leasing Group enters into railcar operating leases with third parties with terms generally ranging between one year and ten years. The majority of our fleet operates on leases that earn fixed monthly lease payments. Generally, lease payments are due at the beginning of the applicable month. A portion of our fleet operates on per diem leases that earn usage-based variable lease payments. Some of our leases include options to extend the leases for up to five years, and a small percentage of our leases include early termination options with certain notice requirements and early termination penalties. As of December 31, 2024, non-lease fleet operating leases in which we are the lessor were not significant, and we had no direct finance leases.
We manage risks associated with residual values of leased railcars by investing across a diverse portfolio of railcar types, staggering lease maturities within any given railcar type, avoiding concentration of railcar type and industry, and actively participating in secondary markets. Additionally, our lease agreements contain normal wear and tear return condition provisions and high mileage thresholds designed to protect the value of our residual assets. Our lease agreements do not contain any material residual value guarantees or restrictive covenants.

Income Taxes
The liability method is used to account for income taxes. Deferred income taxes represent the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and their respective tax bases and other attributes using currently enacted tax laws and tax rates. Valuation allowances reduce deferred tax assets to an amount that will more likely than not be realized.
We regularly evaluate the likelihood of realization of tax benefits derived from positions we have taken in various federal and state filings after consideration of all relevant facts, circumstances, and available information. For those tax positions that are deemed more likely than not to be sustained, we recognize the benefit we believe is cumulatively greater than 50% likely to be realized. To the extent that we were to prevail in matters for which accruals have been established or be required to pay amounts in excess of recorded reserves, the effective tax rate in a given financial statement period could be materially impacted.
Financial Instruments
We consider all highly liquid debt instruments to be either cash and cash equivalents if purchased with a maturity of three months or less, or short-term marketable securities if purchased with a maturity of more than three months and less than one year.
Financial instruments that potentially subject us to a concentration of credit risk are primarily cash investments, including restricted cash and receivables. We place our cash investments in bank deposits, investment grade short-term debt instruments, highly-rated money market funds, and highly-rated commercial paper. We limit the amount of credit exposure to any one commercial issuer. The carrying values of cash, receivables, and accounts payable are considered to be representative of their respective fair values.
Concentrations of credit risk with respect to receivables are limited due to control procedures that monitor the credit worthiness of customers, the large number of customers in our customer base, and their dispersion across different end markets and geographic areas. Receivables are generally evaluated at a portfolio level based on these characteristics. As receivables are generally unsecured, we maintain an allowance for credit losses using a forward-looking approach based on historical losses and consideration of current and expected future economic conditions. Historically, we have observed that the likelihood of loss increases when receivables have aged beyond 180 days. When a receivable is deemed uncollectible, the write-off is recorded as a reduction to the allowance for credit losses. During the year ended December 31, 2024, we recognized approximately $4.3 million of credit loss expense and wrote off $2.8 million related to our trade receivables that are in scope of ASC 326, Financial Instruments – Credit Losses, bringing the allowance for credit losses balance from $12.8 million at December 31, 2023 to $14.3 million at December 31, 2024. This balance excludes the general reserve for operating lease receivables that is permitted under ASC 450, Contingencies.
Inventories
Inventories are valued at the lower of cost or net realizable value. Cost is determined principally on the first in first out method. Work in process and finished goods include material, labor, and overhead.
Property, Plant, and Equipment
Property, plant, and equipment are stated at cost and depreciated over their estimated useful lives using the straight-line method. The costs of ordinary maintenance and repair are charged to operating costs. The estimated useful lives are as follows:
Buildings and improvements
5 – 30 years
Leasehold improvementsGenerally over the term of the lease
Machinery and equipment
Generally 3 – 15 years
Information systems hardware and software
3 – 5 years
Railcars in our lease fleet
Generally 35 – 40 years
Impairment of Long-lived Assets
We periodically evaluate the carrying value of long-lived assets for potential impairment. The carrying value of long-lived assets is considered impaired when their carrying value is not recoverable through undiscounted future cash flows and the fair value of the assets is less than their carrying value. Fair value is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risks involved or market quotes as available. Impairment losses on long-lived assets held for sale are determined in a similar manner, except that fair values are reduced by the estimated cost to dispose of the assets. We did not identify any indicators of impairment during the years ended December 31, 2024, 2023, or 2022.
Goodwill and Intangible Assets
Goodwill is required to be tested for impairment at least annually, or on an interim basis if events or circumstances change indicating that the carrying amount of the goodwill might be impaired. Indefinite-lived intangible assets are not subject to amortization but are required to be evaluated for impairment at least annually. We have the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment assessment. If, after assessing the totality of events and circumstances, we determine that it is more likely than not that the fair value of a reporting unit or an individual indefinite-lived intangible asset is less than its carrying value, the Company will perform the quantitative impairment test. We can also elect to forgo the qualitative assessment and perform the quantitative test.
The quantitative goodwill impairment test compares the reporting unit's estimated fair value with the carrying amount of its net assets. An impairment is recognized if the reporting unit's recorded net assets exceed its fair value. Impairment is assessed at the reporting unit level by applying a fair value-based test for each unit with recorded goodwill. The estimates and judgments that most significantly affect the fair value calculations are assumptions, consisting of Level 3 inputs, related to revenue and operating profit results, discount rates, terminal growth rates, and exit multiples. As of both December 31, 2024 and 2023, goodwill totaled $221.5 million. As of October 1, 2024 and 2023, we completed our annual impairment tests of goodwill at the reporting unit level and determined that no impairment charges were necessary.
If the carrying value of an individual indefinite-lived intangible asset exceeds its fair value, such individual indefinite-lived intangible asset is impaired by the amount of the excess. As of both December 31, 2024 and 2023, indefinite-lived intangible assets, which are comprised of trade names of recently acquired businesses, totaled $11.2 million. As of October 1, 2024 and 2023, we completed our evaluations of each indefinite-lived intangible asset and determined that no impairment charges were necessary.
The net book value of our finite-lived intangible assets totaled $87.8 million and $95.5 million as of December 31, 2024 and 2023, respectively, which are amortized over their estimated useful lives, ranging from one year to fifteen years. We evaluate the carrying value of our finite-lived intangible assets for potential impairment when events and circumstances indicate that the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. We did not identify any impairment indicators during the years ended December 31, 2024, 2023, or 2022.
See Note 8 for further information regarding goodwill and intangible assets.
Restricted Cash
Restricted cash consists of cash and cash equivalents held as collateral for our non-recourse debt and lease obligations. As such, they are restricted in use.
Investments in Affiliates
We regularly assess our investments in and other contractual arrangements with third-party entities to determine whether they are considered a variable interest entity ("VIE") and, if so, whether we are considered the primary beneficiary. Consolidation is required for VIEs in which we are the primary beneficiary. We have determined that we are the primary beneficiary for TRIP Holdings, RIV 2013, and Trinity Global Ventures. At December 31, 2024, the carrying value of our investments in these entities totaled $133.0 million. See Note 5 for further information regarding investments in which we have a controlling interest.
Insurance
We are effectively self-insured for workers' compensation and employee health care claims. A third-party administrator is used to process claims. We accrue our workers' compensation and group medical liabilities based upon independent actuarial studies. These liabilities are calculated based upon loss development factors, which contemplate a number of variables, including claims history and expected trends. As of December 31, 2024 and 2023, our liabilities associated with workers' compensation were $30.6 million and $35.0 million, respectively, and our liabilities associated with group medical insurance were $3.8 million and $4.5 million, respectively. These amounts are included in the accrued liabilities line of our Consolidated Balance Sheets.
Supply Chain Finance Program
In cooperation with a participating financial institution, we facilitate a voluntary supply chain finance ("SCF") program for several of our suppliers. We negotiate payment terms with suppliers that are in line with average industry terms. We have not pledged any assets as security or provided other forms of guarantees to the financial institution. Under the SCF program, participating suppliers may choose to sell, at a discounted price, receivables due from us to the financial institution, at the sole discretion of both the suppliers and the financial institution, prior to the invoices’ scheduled due dates. The payment terms that we negotiate with all suppliers are consistent regardless of whether the supplier chooses to participate in the SCF program for a particular invoice. The SCF program is administered by a third-party financial institution, and our responsibility is limited to making payments based on the terms originally negotiated with participating suppliers, regardless of whether such suppliers sell receivables to the financial institution.
Amounts due to our participating suppliers in the SCF program are included in accounts payable in our Consolidated Balance Sheets. Payments made under the SCF program are reflected in net cash provided by operating activities from continuing operations in our Consolidated Statements of Cash Flows. The following is a summary of our outstanding obligations confirmed as valid under the supplier finance program for the year ended December 31, 2024:
Year Ended

$18.3 
Invoices confirmed 75.8 
Confirmed invoices paid (85.9)
Confirmed obligations outstanding at December 31, 2024
$8.2 
Warranties
We provide various express, limited product warranties that generally range from one year to five years depending on the product. The warranty costs are estimated using a two-step approach. First, an engineering estimate is made for the cost of all claims that have been asserted by customers. Second, based on historical claims experience, a cost is accrued for all products still within a warranty period for which no claims have been filed. We provide for the estimated cost of product warranties at the time revenue is recognized related to products covered by warranties and assess the adequacy of the resulting reserves on a quarterly basis. As of December 31, 2024 and 2023, our accruals for warranties totaled $2.9 million and $3.3 million, respectively, and are included in accrued liabilities in our Consolidated Balance Sheets.
Foreign Currency Transactions
The functional currency of our Mexico and Canada operations is the United States dollar. Certain transactions in these countries occur in currencies other than the United States dollar. The remeasurement impact of foreign currency fluctuations on these transactions is recorded in other, net (income) expense in our Consolidated Statements of Operations.
Other Comprehensive Income (Loss)
Other comprehensive net income (loss) consists of foreign currency translation adjustments, unrealized gains and losses on our derivative financial instruments, and the net actuarial gains and losses of our defined benefit plans, the sum of which, together with net income (loss), constitutes comprehensive income (loss). See Note 12. All components are shown net of tax.
Recent Accounting Pronouncements
Adopted in 2024
ASU 2023-07 – In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") No. 2023-07, "Improvements to Reportable Segment Disclosures," which improves disclosures about a public entity's reportable segments through enhanced disclosures about significant segment expenses. ASU 2023-07 requires disclosures, on an annual and interim basis, of significant segment expenses that are regularly provided to the CODM, the amount for other segment items by reportable segment and a description of its composition, the title and position of the CODM, and interim period disclosure of all current ASC 280, Segment Reporting, annual disclosures about a reportable segment's profit or loss and assets. We adopted ASU 2023-07 on a retrospective basis. See Note 4 for our reportable segment disclosures, including significant segment expenses.
Not Yet Adopted
ASU 2023-09 – In December 2023, the FASB issued ASU No. 2023-09, "Improvements to Income Tax Disclosures," which enhances transparency and decision usefulness of income tax disclosures. ASU 2023-09 requires, on an annual basis, a tabular disclosure using specific categories in the rate reconciliation and providing additional information for reconciling items that meet a quantitative threshold, as well as the disaggregation of income taxes paid by federal, state, and foreign jurisdictions. ASU 2023-09 is effective for public companies during annual reporting periods beginning after December 15, 2024 on a prospective basis, with an option for retrospective application. We are currently evaluating the impact ASU 2023-09 will have on our income tax disclosures.
ASU 2024-03 – In November 2024, the FASB issued ASU No. 2024-03, "Disaggregation of Income Statement Expenses," which improves financial reporting and responds to investor input by requiring public companies to disclose additional information about certain expenses in the notes to the consolidated financial statements. ASU 2024-03 requires disclosures, on an annual and interim basis, of the amounts of purchases of inventory, employee compensation, depreciation, and intangible asset amortization included in each relevant expense category; a qualitative description of amounts remaining that are not separately disaggregated quantitatively; and the amount of selling expenses and, in annual reporting periods, the definition of selling expenses. ASU 2024-03 is effective for public companies during annual reporting periods beginning after December 15, 2026 on a prospective basis, with an option for retrospective application. Early adoption is permitted. We are currently evaluating the impact ASU 2024-03 will have on our financial statement disclosures.
Management's Estimates
The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Consolidation, Policy [Policy Text Block]
Principles of Consolidation
The financial statements of Trinity Industries, Inc. and Subsidiaries (“Trinity,” “Company,” “we,” “our,” or "us") include the accounts of our wholly-owned subsidiaries and our partially-owned subsidiaries, TRIP Rail Holdings LLC ("TRIP Holdings"), RIV 2013 Rail Holdings LLC ("RIV 2013"), and Trinity Global Ventures Limited ("Trinity Global Ventures"), in which we have a controlling interest. All significant intercompany accounts and transactions have been eliminated. Certain prior year balances have been reclassified to conform to the 2024 presentation.
Segment Reporting, Policy
Our Reportable Segments
Effective January 1, 2024, the Company modified its organizational structure to better leverage our maintenance services capabilities to support lease fleet optimization and to grow our services and parts businesses. The new structure resulted in a change to our reportable segments beginning in 2024. In connection with this organizational update, we aligned the maintenance services business, which was previously reported in the Rail Products Group, to now be presented within our leasing business. This change aligns with the way in which our Chief Operating Decision Maker ("CODM") assesses performance and allocates resources. Consequently, beginning January 1, 2024, we report our operating results in two reportable segments: (1) the Railcar Leasing and Services Group, formerly the Railcar Leasing and Management Services Group, and (2) the Rail Products Group. These changes had no impact to our previously reported consolidated results of operations, financial position, or cash flows. All prior period segment results set forth herein have been recast to reflect these changes and present results on a comparable basis.
Revenue
Revenue Recognition
Revenue associated with our railcar lease contracts is recognized in accordance with Accounting Standards Codification ("ASC") 842, Leases. Revenue associated with our railcar manufacturing, maintenance services, digital and logistics services businesses, and certain servicing, maintenance, and management agreements is recognized in accordance with ASC 606, Revenue from Contracts with Customers.
Revenue is measured based on the allocation of the transaction price in a contract to satisfied performance obligations. The transaction price does not include any amounts collected on behalf of third parties. We recognize revenue when we satisfy a performance obligation by transferring control over a product or service to a customer. For all contracts with customers, we evaluate whether we are the principal (i.e., report revenues on a gross basis) or agent (i.e., report revenues on a net basis). Generally, we are the principal in our contracts with customers and report revenues on a gross basis as we control the product or service before it is transferred to a customer. We act as an agent for a small number of service contracts and report those revenues on a net basis as we do not control the services before they are provided to the customer. Payments for our products and services are generally due within normal commercial terms.
The following is a description of principal activities from which we generate our revenue, separated by reportable segments. See Note 4 for a further discussion regarding our reportable segments.
Railcar Leasing and Services Group
In our Railcar Leasing and Services Group ("Leasing Group"), revenue from rentals and operating leases, including contracts that contain non-level fixed lease payments, is recognized monthly on a straight-line basis. Leases not classified as operating leases are generally considered sales-type leases as a result of an option to purchase.
We review our operating lease receivables for collectibility on a regular basis, taking into consideration changes in factors such as the lessee’s payment history, the financial condition of the lessee, and business and economic conditions in the industry in which the lessee operates. In the event that the collectibility of a receivable with respect to any lessee is no longer probable, we derecognize the revenue and related receivable and recognize future revenue only when the lessee makes a rental payment. Contingent rents are recognized when the contingency is resolved.
Selling profit or loss associated with sales-type leases is recognized upon lease commencement, and a net investment in the sales-type lease is recorded in the Consolidated Balance Sheets. Interest income related to sales-type leases is recognized over the lease term using the effective interest method. See "Lease Accounting" below for additional information regarding sales-type leases as of December 31, 2024 and 2023.
We report all sales of railcars from the lease fleet and selling profit or loss associated with sales-type leases as a net gain or loss from the disposal of a long-term asset in accordance with ASC 610-20, Gains and losses from the derecognition of non-financial assets. These sales are presented in the Lease portfolio sales line in our Consolidated Statements of Operations.
Our maintenance services business is primarily dedicated to servicing our lease fleet. Revenues related to maintenance services performed on Company-owned railcars under full-service lease agreements are eliminated within the Railcar Leasing and Services Group. Services that are not included in the full-service lease agreement, such as repairs of railcar damage or other customer-specific requirements, as well as maintenance and repair activities on railcars owned by third parties, including our investor-owned fleet, are reflected in the Leasing Group's revenues and are not eliminated in consolidation.
Within maintenance services, revenue is recognized over time as repair and maintenance projects are completed, using an input approach based on the costs incurred relative to the total estimated costs of performing the project. We recorded contract assets of $9.6 million and $8.8 million as of December 31, 2024 and December 31, 2023, respectively, related to unbilled revenues recognized on repair and maintenance activities that have been performed, but for which the entire project has not yet been completed, and the railcar has not yet been shipped to the customer. These contract assets are included within the Receivables, net of allowance line in our Consolidated Balance Sheets.
In connection with an acquisition that occurred during the first quarter of 2023, we evaluated whether we are acting as a principal or an agent for certain logistics services provided to a small number of customers. During the fourth quarter of 2023, we concluded that we act as an agent in these transactions as we do not control the services before they are provided to the customer, and as a result, revenues that were previously recognized on a gross basis should be recognized on a net basis. We elected to effect this accounting change on a prospective basis as it was not quantitatively or qualitatively material to our consolidated financial statements, and beginning in the fourth quarter of 2023, revenues associated with these services are now recognized on a net basis. The accounting change had no effect on the Company's previously reported operating profit, net income, earnings per share, Consolidated Balance Sheets, or Consolidated Statements of Cash Flows.
Rail Products Group
Our railcar manufacturing business recognizes revenue related to new railcars at a point in time when the customer has submitted its certificate of acceptance and legal title of the railcar has passed to the customer. Certain contracts for the sales of railcars include price adjustments based on changes to input costs; this amount represents variable consideration for which we are generally unable to estimate the final consideration until the railcar is delivered.
Revenue related to sustainable railcar conversions is recognized over time as sustainable railcar conversions are completed, using an input approach based on the costs incurred relative to the total estimated costs of performing the project. Revenue related to certain support services is recognized over time based on our stand-ready obligation to provide such services. We recorded contract assets of $3.4 million and $12.6 million as of December 31, 2024 and 2023, respectively. These contract assets are included within the Receivables, net of allowance line in our Consolidated Balance Sheets.
We account for shipping and handling costs as activities to fulfill the promise to transfer the good; as such, these fees are recorded in revenue. The fees and costs of shipping and handling activities are accrued when the related performance obligation has been satisfied.
Unsatisfied Performance Obligations
The following table includes estimated revenue expected to be recognized in future periods related to performance obligations that are unsatisfied or partially satisfied as of December 31, 2024 and the percentage of the outstanding performance obligations as of December 31, 2024 expected to be delivered during 2025:

The final amount of backlog attributable to the Leasing Group may vary by the time of delivery as customers may elect to change their procurement decision.
Unsatisfied performance obligations for the Railcar Leasing and Services Group are related to servicing, maintenance, and management agreements and are expected to be performed through 2029.
Lessee, Leases [Policy Text Block]
Lessee
We are the lessee of operating leases predominantly for office buildings and railcars, as well as manufacturing equipment and office equipment. Our operating leases have remaining lease terms ranging from one year to twelve years, some of which include options to extend for up to five years, and some of which include options to terminate within one year. As of December 31, 2024, we had no material finance leases in which we were the lessee. Certain of our operating leases include lease incentives, which reduce the right-of-use asset and are recognized on a straight-line basis over the lease term.

Lessor, Leases [Policy Text Block]
Lessor
Our Leasing Group enters into railcar operating leases with third parties with terms generally ranging between one year and ten years. The majority of our fleet operates on leases that earn fixed monthly lease payments. Generally, lease payments are due at the beginning of the applicable month. A portion of our fleet operates on per diem leases that earn usage-based variable lease payments. Some of our leases include options to extend the leases for up to five years, and a small percentage of our leases include early termination options with certain notice requirements and early termination penalties. As of December 31, 2024, non-lease fleet operating leases in which we are the lessor were not significant, and we had no direct finance leases.
We manage risks associated with residual values of leased railcars by investing across a diverse portfolio of railcar types, staggering lease maturities within any given railcar type, avoiding concentration of railcar type and industry, and actively participating in secondary markets. Additionally, our lease agreements contain normal wear and tear return condition provisions and high mileage thresholds designed to protect the value of our residual assets. Our lease agreements do not contain any material residual value guarantees or restrictive covenants.

Income Tax, Policy [Policy Text Block]
Income Taxes
The liability method is used to account for income taxes. Deferred income taxes represent the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and their respective tax bases and other attributes using currently enacted tax laws and tax rates. Valuation allowances reduce deferred tax assets to an amount that will more likely than not be realized.
We regularly evaluate the likelihood of realization of tax benefits derived from positions we have taken in various federal and state filings after consideration of all relevant facts, circumstances, and available information. For those tax positions that are deemed more likely than not to be sustained, we recognize the benefit we believe is cumulatively greater than 50% likely to be realized. To the extent that we were to prevail in matters for which accruals have been established or be required to pay amounts in excess of recorded reserves, the effective tax rate in a given financial statement period could be materially impacted.
Cash and Cash Equivalents, Policy [Policy Text Block]
Financial Instruments
We consider all highly liquid debt instruments to be either cash and cash equivalents if purchased with a maturity of three months or less, or short-term marketable securities if purchased with a maturity of more than three months and less than one year.
Financial instruments that potentially subject us to a concentration of credit risk are primarily cash investments, including restricted cash and receivables. We place our cash investments in bank deposits, investment grade short-term debt instruments, highly-rated money market funds, and highly-rated commercial paper. We limit the amount of credit exposure to any one commercial issuer. The carrying values of cash, receivables, and accounts payable are considered to be representative of their respective fair values.
Concentration Risk, Credit Risk, Policy [Policy Text Block] Concentrations of credit risk with respect to receivables are limited due to control procedures that monitor the credit worthiness of customers, the large number of customers in our customer base, and their dispersion across different end markets and geographic areas. Receivables are generally evaluated at a portfolio level based on these characteristics. As receivables are generally unsecured, we maintain an allowance for credit losses using a forward-looking approach based on historical losses and consideration of current and expected future economic conditions. Historically, we have observed that the likelihood of loss increases when receivables have aged beyond 180 days. When a receivable is deemed uncollectible, the write-off is recorded as a reduction to the allowance for credit losses. During the year ended December 31, 2024, we recognized approximately $4.3 million of credit loss expense and wrote off $2.8 million related to our trade receivables that are in scope of ASC 326, Financial Instruments – Credit Losses, bringing the allowance for credit losses balance from $12.8 million at December 31, 2023 to $14.3 million at December 31, 2024. This balance excludes the general reserve for operating lease receivables that is permitted under ASC 450, Contingencies.
Inventory, Policy [Policy Text Block]
Inventories
Inventories are valued at the lower of cost or net realizable value. Cost is determined principally on the first in first out method. Work in process and finished goods include material, labor, and overhead.
Property, Plant and Equipment, Policy [Policy Text Block]
Property, Plant, and Equipment
Property, plant, and equipment are stated at cost and depreciated over their estimated useful lives using the straight-line method. The costs of ordinary maintenance and repair are charged to operating costs. The estimated useful lives are as follows:
Buildings and improvements
5 – 30 years
Leasehold improvementsGenerally over the term of the lease
Machinery and equipment
Generally 3 – 15 years
Information systems hardware and software
3 – 5 years
Railcars in our lease fleet
Generally 35 – 40 years
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]
Impairment of Long-lived Assets
We periodically evaluate the carrying value of long-lived assets for potential impairment. The carrying value of long-lived assets is considered impaired when their carrying value is not recoverable through undiscounted future cash flows and the fair value of the assets is less than their carrying value. Fair value is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risks involved or market quotes as available. Impairment losses on long-lived assets held for sale are determined in a similar manner, except that fair values are reduced by the estimated cost to dispose of the assets. We did not identify any indicators of impairment during the years ended December 31, 2024, 2023, or 2022.
Goodwill and Intangible Assets, Policy [Policy Text Block]
Goodwill and Intangible Assets
Goodwill is required to be tested for impairment at least annually, or on an interim basis if events or circumstances change indicating that the carrying amount of the goodwill might be impaired. Indefinite-lived intangible assets are not subject to amortization but are required to be evaluated for impairment at least annually. We have the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment assessment. If, after assessing the totality of events and circumstances, we determine that it is more likely than not that the fair value of a reporting unit or an individual indefinite-lived intangible asset is less than its carrying value, the Company will perform the quantitative impairment test. We can also elect to forgo the qualitative assessment and perform the quantitative test.
The quantitative goodwill impairment test compares the reporting unit's estimated fair value with the carrying amount of its net assets. An impairment is recognized if the reporting unit's recorded net assets exceed its fair value. Impairment is assessed at the reporting unit level by applying a fair value-based test for each unit with recorded goodwill. The estimates and judgments that most significantly affect the fair value calculations are assumptions, consisting of Level 3 inputs, related to revenue and operating profit results, discount rates, terminal growth rates, and exit multiples. As of both December 31, 2024 and 2023, goodwill totaled $221.5 million. As of October 1, 2024 and 2023, we completed our annual impairment tests of goodwill at the reporting unit level and determined that no impairment charges were necessary.
If the carrying value of an individual indefinite-lived intangible asset exceeds its fair value, such individual indefinite-lived intangible asset is impaired by the amount of the excess. As of both December 31, 2024 and 2023, indefinite-lived intangible assets, which are comprised of trade names of recently acquired businesses, totaled $11.2 million. As of October 1, 2024 and 2023, we completed our evaluations of each indefinite-lived intangible asset and determined that no impairment charges were necessary.
The net book value of our finite-lived intangible assets totaled $87.8 million and $95.5 million as of December 31, 2024 and 2023, respectively, which are amortized over their estimated useful lives, ranging from one year to fifteen years. We evaluate the carrying value of our finite-lived intangible assets for potential impairment when events and circumstances indicate that the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. We did not identify any impairment indicators during the years ended December 31, 2024, 2023, or 2022.
See Note 8 for further information regarding goodwill and intangible assets.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]
Restricted Cash
Restricted cash consists of cash and cash equivalents held as collateral for our non-recourse debt and lease obligations. As such, they are restricted in use.
Variable Interest Entity Disclosure [Text Block]
Investments in Affiliates
We regularly assess our investments in and other contractual arrangements with third-party entities to determine whether they are considered a variable interest entity ("VIE") and, if so, whether we are considered the primary beneficiary. Consolidation is required for VIEs in which we are the primary beneficiary. We have determined that we are the primary beneficiary for TRIP Holdings, RIV 2013, and Trinity Global Ventures. At December 31, 2024, the carrying value of our investments in these entities totaled $133.0 million. See Note 5 for further information regarding investments in which we have a controlling interest.
Self Insurance Reserve [Policy Text Block]
Insurance
We are effectively self-insured for workers' compensation and employee health care claims. A third-party administrator is used to process claims. We accrue our workers' compensation and group medical liabilities based upon independent actuarial studies. These liabilities are calculated based upon loss development factors, which contemplate a number of variables, including claims history and expected trends. As of December 31, 2024 and 2023, our liabilities associated with workers' compensation were $30.6 million and $35.0 million, respectively, and our liabilities associated with group medical insurance were $3.8 million and $4.5 million, respectively. These amounts are included in the accrued liabilities line of our Consolidated Balance Sheets.
Supplier Finance Program
Supply Chain Finance Program
In cooperation with a participating financial institution, we facilitate a voluntary supply chain finance ("SCF") program for several of our suppliers. We negotiate payment terms with suppliers that are in line with average industry terms. We have not pledged any assets as security or provided other forms of guarantees to the financial institution. Under the SCF program, participating suppliers may choose to sell, at a discounted price, receivables due from us to the financial institution, at the sole discretion of both the suppliers and the financial institution, prior to the invoices’ scheduled due dates. The payment terms that we negotiate with all suppliers are consistent regardless of whether the supplier chooses to participate in the SCF program for a particular invoice. The SCF program is administered by a third-party financial institution, and our responsibility is limited to making payments based on the terms originally negotiated with participating suppliers, regardless of whether such suppliers sell receivables to the financial institution.
Amounts due to our participating suppliers in the SCF program are included in accounts payable in our Consolidated Balance Sheets. Payments made under the SCF program are reflected in net cash provided by operating activities from continuing operations in our Consolidated Statements of Cash Flows. The following is a summary of our outstanding obligations confirmed as valid under the supplier finance program for the year ended December 31, 2024:

Standard Product Warranty, Policy [Policy Text Block]
Warranties
We provide various express, limited product warranties that generally range from one year to five years depending on the product. The warranty costs are estimated using a two-step approach. First, an engineering estimate is made for the cost of all claims that have been asserted by customers. Second, based on historical claims experience, a cost is accrued for all products still within a warranty period for which no claims have been filed. We provide for the estimated cost of product warranties at the time revenue is recognized related to products covered by warranties and assess the adequacy of the resulting reserves on a quarterly basis. As of December 31, 2024 and 2023, our accruals for warranties totaled $2.9 million and $3.3 million, respectively, and are included in accrued liabilities in our Consolidated Balance Sheets.
Foreign Currency Transactions and Translations Policy [Policy Text Block]
Foreign Currency Transactions
The functional currency of our Mexico and Canada operations is the United States dollar. Certain transactions in these countries occur in currencies other than the United States dollar. The remeasurement impact of foreign currency fluctuations on these transactions is recorded in other, net (income) expense in our Consolidated Statements of Operations.
Comprehensive Income, Policy [Policy Text Block]
Other Comprehensive Income (Loss)
Other comprehensive net income (loss) consists of foreign currency translation adjustments, unrealized gains and losses on our derivative financial instruments, and the net actuarial gains and losses of our defined benefit plans, the sum of which, together with net income (loss), constitutes comprehensive income (loss). See Note 12. All components are shown net of tax.
New Accounting Pronouncements, Policy [Policy Text Block]
Recent Accounting Pronouncements
Adopted in 2024
ASU 2023-07 – In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") No. 2023-07, "Improvements to Reportable Segment Disclosures," which improves disclosures about a public entity's reportable segments through enhanced disclosures about significant segment expenses. ASU 2023-07 requires disclosures, on an annual and interim basis, of significant segment expenses that are regularly provided to the CODM, the amount for other segment items by reportable segment and a description of its composition, the title and position of the CODM, and interim period disclosure of all current ASC 280, Segment Reporting, annual disclosures about a reportable segment's profit or loss and assets. We adopted ASU 2023-07 on a retrospective basis. See Note 4 for our reportable segment disclosures, including significant segment expenses.
Not Yet Adopted
ASU 2023-09 – In December 2023, the FASB issued ASU No. 2023-09, "Improvements to Income Tax Disclosures," which enhances transparency and decision usefulness of income tax disclosures. ASU 2023-09 requires, on an annual basis, a tabular disclosure using specific categories in the rate reconciliation and providing additional information for reconciling items that meet a quantitative threshold, as well as the disaggregation of income taxes paid by federal, state, and foreign jurisdictions. ASU 2023-09 is effective for public companies during annual reporting periods beginning after December 15, 2024 on a prospective basis, with an option for retrospective application. We are currently evaluating the impact ASU 2023-09 will have on our income tax disclosures.
ASU 2024-03 – In November 2024, the FASB issued ASU No. 2024-03, "Disaggregation of Income Statement Expenses," which improves financial reporting and responds to investor input by requiring public companies to disclose additional information about certain expenses in the notes to the consolidated financial statements. ASU 2024-03 requires disclosures, on an annual and interim basis, of the amounts of purchases of inventory, employee compensation, depreciation, and intangible asset amortization included in each relevant expense category; a qualitative description of amounts remaining that are not separately disaggregated quantitatively; and the amount of selling expenses and, in annual reporting periods, the definition of selling expenses. ASU 2024-03 is effective for public companies during annual reporting periods beginning after December 15, 2026 on a prospective basis, with an option for retrospective application. Early adoption is permitted. We are currently evaluating the impact ASU 2024-03 will have on our financial statement disclosures.
Use of Estimates, Policy [Policy Text Block]
Management's Estimates
The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
