Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Note 1 . Summary of Significant Accounting Policies Principles of Consolidation The financial statements of Trinity Industries, Inc. and its consolidated subsidiaries (“Trinity,” “Company,” “we,” “our,” or "us") include the accounts of its wholly-owned subsidiaries and its partially-owned subsidiaries, TRIP Rail Holdings LLC ("TRIP Holdings") and RIV 2013 Rail Holdings LLC ("RIV 2013"), in which we have a controlling interest. All significant intercompany accounts and transactions have been eliminated. Spin-off of Arcosa, Inc. Upon completion of the spin-off of Arcosa, Inc. ("Arcosa") on November 1, 2018, the accounting requirements for reporting Arcosa as a discontinued operation were met. Accordingly, Arcosa's results of operations are presented as discontinued operations for all periods in this Form 10-K. See Note 2 for further information related to the spin-off transaction. Revenue Recognition 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. 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 Management Services Group In our Railcar Leasing and Management 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 de-recognize 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 on the Consolidated Balance Sheet. Interest income related to sales-type leases is recognized over the lease term using the effective interest method. Revenue is recognized from the sales of railcars from the lease fleet on a gross basis in leasing revenues and cost of revenues if the railcar has been owned for one year or less at the time of sale. Sales of railcars from the lease fleet owned for more than one year are recognized as a net gain or loss from the disposal of a long-term asset. Revenue from servicing and management agreements is recognized as each performance period occurs. 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. Rail Products Group Our railcar manufacturing business recognizes revenue when the customer has submitted its certificate of acceptance and legal title of the railcar has passed to the customer. Certain long-term contracts for the sales of railcars include price adjustments based on steel-price indices; this amount represents variable consideration for which we are unable to estimate the final consideration until the railcar is delivered, at which time the pricing becomes fixed. Within our maintenance services business, 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 $5.2 million and $10.2 million as of December 31, 2019 and 2018 , respectively, related to unbilled revenues recognized on repair and maintenance services that have been performed, but for which the entire project has not yet been completed.

Unsatisfied performance obligations for the Railcar Leasing and Management 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 railcars, as well as office buildings, manufacturing equipment, and office equipment. Our operating leases have remaining lease terms ranging from one year to forty 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, 2019 , we had no finance leases in which we were the lessee. The following table summarizes the impact of our operating leases on our Consolidated Financial Statements (in millions, except lease term and discount rate): Year Ended December 31, 2019 Consolidated Statement of Operations Operating lease expense $ 18.0 Short-term lease expense $ 4.1 December 31, 2019 Consolidated Balance Sheet Right-of-use assets (1) $ 44.2 Lease liabilities (2) $ 44.8 Weighted average remaining lease term 4.8 years Weighted average discount rate 4.1 % Year Ended December 31, 2019 Consolidated Statement of Cash Flows Cash flows from operating activities $ 18.0 Right-of-use assets recognized in exchange for new lease liabilites $ 10.3 (1) Included in other assets in our Consolidated Balance Sheet (2) Included in other liabilities in our Consolidated Balance Sheet Future contractual minimum operating lease liabilities will mature as follows (in millions): Leasing Group Non-Leasing Group Total 2020 $ 10.1 $ 3.9 $ 14.0 2021 8.6 2.8 11.4 2022 7.8 2.6 10.4 2023 5.9 2.2 8.1 2024 2.7 1.1 3.8 Thereafter 1.5 2.9 4.4 Total operating lease payments $ 36.6 $ 15.5 $ 52.1 Less: Present value adjustment (7.3 ) Total operating lease liabilities $ 44.8 Lessor Our Leasing Group enters into railcar operating leases with third parties with terms generally ranging between one year and ten years , although certain leases entered into in prior periods had lease terms of up to twenty years . The majority of our fleet operates on leases that earn fixed monthly lease payments. 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 options to terminate within one year with certain notice requirements and early termination penalties. Our sales-type leases include an option for the lessee to purchase the leased railcars with certain notice. As of December 31, 2019 , non-Leasing Group operating leases 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 participating in active 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. The following table summarizes the impact of our leases on our Consolidated Statement of Operations (in millions): Year Ended December 31, 2019 Operating lease revenues $ 676.3 Variable operating lease revenues 50.5 Sales-type lease revenues 160.5 Interest income on sales-type lease receivables 2.4 Profit recognized at sales-type lease commencement 19.0 Future contractual minimum lease receivables for sales-type leases will mature as follows (in millions): 2020 $ 43.4 2021 131.8 2022 — 2023 — 2024 — Thereafter — Total $ 175.2 Less: Unearned interest income (20.7 ) Net investment in sales-type leases (1) $ 154.5 (1) Included in other assets in our Consolidated Balance Sheet Future contractual minimum revenues for operating leases will mature as follows (in millions): 2020 $ 568.1 2021 451.9 2022 347.1 2023 243.7 2024 154.0 Thereafter 268.3 Total $ 2,033.1 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 the amounts used for income tax purposes. 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 and investment grade, short-term debt instruments and limit the amount of credit exposure to any one commercial issuer. 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. As receivables are generally unsecured, we maintain an allowance for doubtful accounts based upon the expected collectibility of all receivables. Receivable balances determined to be uncollectible are charged against the allowance. The carrying values of cash, receivables, and accounts payable are considered to be representative of their respective fair values. 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 3 – 30 years Leasehold improvements The lesser of the term of the lease or 7 years Machinery and equipment 2 – 10 years Information systems hardware and software 2 – 5 years Railcars in our lease fleet Generally 35 years As of early 2020, we are finalizing an assessment of the estimated useful lives and salvage value assumptions for the railcars in our lease fleet. Based upon analysis of historical fleet data, review of industry standards, and consideration of certain economic factors by railcar type, we have determined that it is appropriate to revise the useful lives and salvage values of certain railcar types in our lease fleet. We believe that the revised useful lives reflect the estimated economic lives of the railcars in our lease fleet. The net impact of these changes, which will become effective January 1, 2020, is expected to result in a change in the weighted average useful life of railcars in our lease fleet from approximately 34 years to approximately 37 years . This change will be accounted for as a change in accounting estimate, which is required to be accounted for on a prospective basis. Based on the composition of the lease fleet as of December 31, 2019, we expect this change to result in a net decrease in annual depreciation expense of between $27 million and $33 million for the year ended December 31, 2020. 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. Based on our evaluations, no impairment charges were determined to be necessary on assets held and used as of December 31, 2019 and 2018 . 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. The quantitative goodwill impairment test is a two-step process, with step one requiring the comparison of the reporting unit's estimated fair value with the carrying amount of its net assets. If necessary, step two of the impairment test determines the amount of goodwill impairment to be recorded when 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 three inputs, related to revenue and operating profit results, discount rates, terminal growth rates and exit multiples. As of December 31, 2019 and 2018 , our annual impairment test of goodwill was completed at the reporting unit level, and no impairment charges were determined to be necessary. The net book value of intangible assets totaled $18.7 million and $22.4 million as of December 31, 2019 and 2018 , respectively, and included finite-lived intangible assets of $16.2 million and $19.9 million , respectively, which are amortized over their estimated useful lives ranging from one year to twenty years . Based on our evaluations of intangible assets, no impairment charges were determined to be necessary as of December 31, 2019 and 2018 . Goodwill by segment is as follows: December 31, 2019 December 31, 2018 (in millions) Railcar Leasing and Management Services Group $ 1.8 $ 1.8 Rail Products Group 145.4 145.4 All Other 61.6 61.6 $ 208.8 $ 208.8 Restricted Cash Restricted cash consists of cash and cash equivalents held either as collateral for our non-recourse debt and lease obligations or as security for the performance of certain product sales agreements. As such, they are restricted in use. Investments in Affiliates We continuously evaluate our investments and other contractual arrangements with third party entities to determine if our variable interests are considered a variable interest entity ("VIE"). Consolidation is required for VIEs in which we are the primary beneficiary. We have determined that we are the primary beneficiary for TRIP Holdings and RIV 2013. At December 31, 2019 , the carrying value of our investment in TRIP Holdings and RIV 2013 totaled $186.5 million . For further information regarding our partially-owned leasing subsidiaries, see Note 5 of the Consolidated Financial Statements. Other Investments We hold certain other investments for which we do not have a controlling financial interest but have a significant influence over the financial and operating policies. The carrying values of our equity method investments totaled approximately $3.8 million and $3.4 million as of December 31, 2019 and 2018 , respectively. 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. 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. The changes in the accruals for warranties for the years ended December 31, 2019 , 2018 , and 2017 are as follows: Year Ended December 31, 2019 2018 2017 (in millions) Beginning balance $ 7.4 $ 10.1 $ 12.0 Warranty costs incurred (3.8 ) (2.8 ) (4.8 ) Warranty originations and revisions 4.5 0.1 4.8 Warranty expirations — — (1.9 ) Ending balance $ 8.1 $ 7.4 $ 10.1 Foreign Currency Transactions The functional currency of our Mexico operations is the United States dollar. Certain transactions in Mexico occur in currencies other than the United States dollar. The impact of foreign currency fluctuations on these transactions is recorded in other, net (income) expense in our Consolidated Statement 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 2019 ASU 2016-02 — In February 2016, the FASB issued ASU No. 2016-02, "Leases", ("ASC 842") which amended the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. ASC 842 is effective for public companies during interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. In July 2018, the FASB issued ASU No. 2018-11, which permitted entities to record the right-of-use asset and lease liability on the date of adoption, with no requirement to recast comparative periods. We adopted ASC 842 effective January 1, 2019 using the optional transition method of recognizing a cumulative-effect adjustment to the opening balance of retained earnings on January 1, 2019. Therefore, comparative financial information was not adjusted and continues to be reported under the prior lease accounting guidance in ASC 840. We elected the transition relief package of practical expedients, and as a result, we did not assess 1) whether existing or expired contracts contain embedded leases, 2) lease classification for any existing or expired leases, and 3) whether lease origination costs qualified as initial direct costs. We elected the short-term lease practical expedient by establishing an accounting policy to exclude leases with a term of 12 months or less, as well as the land easement practical expedient for maintaining our current accounting policy for existing or expired land easements. For qualifying operating leases in which we are the lessor, we do not separate lease components for our leased railcars from non-lease components, which are comprised of stand-ready maintenance obligations. We did not elect the practical expedient to use hindsight in determining a lease term and impairment of right-of-use assets at the adoption date. Upon adoption, we recognized right-of-use assets and corresponding lease liabilities of $47.0 million and $48.3 million , respectively, in our Consolidated Balance Sheet based on the present value of future minimum lease payments under operating leases for which we are the lessee. This excluded the impact of railcars that were previously under operating leases as of January 1, 2019 but which were purchased on January 14, 2019 and are now wholly-owned by our Leasing Group. Additionally, we recorded an adjustment to opening retained earnings of $17.7 million ( $13.7 million , net of tax) related to the derecognition of deferred profit related to sale-leaseback transactions. Our accounting treatment under ASC 842 for leases in which we are the lessor remained substantially unchanged from our accounting treatment under ASC 840. The adoption of ASC 842 did not have a significant impact on our consolidated results of operations or cash flows. ASU 2018-16 — In October 2018, the FASB issued ASU No. 2018-16, "Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes," which permits the use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815. ASU 2018-16 is effective for public companies during interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. We adopted ASU 2018-16 effective January 1, 2019 on a prospective basis for qualifying new or redesignated hedges. The adoption did not have a significant impact on our Consolidated Financial Statements and did not impact pre-existing hedges. Effective in 2020 ASU 2016-13 — In June 2016, the FASB issued ASU No. 2016-13, "Measurement of Credit Losses on Financial Instruments," which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses rather than incurred losses to estimate credit losses on certain types of financial instruments, including trade receivables. This approach may result in the earlier recognition of allowances for losses. In November 2018, the FASB issued ASU No. 2018-19, "Codification Improvements to Topic 326, Financial Instruments—Credit Losses," which excludes operating lease receivables from the scope of ASU 2016-13. ASU 2016-13 is effective for public companies during interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. We are adopting ASU 2016-13 effective January 1, 2020, and we do not currently expect a material opening retained earnings adjustment as a result of the adoption. Further, we do not expect the ongoing application of ASU 2016-13 to materially impact our Consolidated Financial Statements. ASU 2018-15 — In August 2018, the FASB issued ASU No. 2018-15, "Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract," which aligns the accounting for costs incurred to implement a cloud computing arrangement that is a service arrangement with the guidance on capitalizing costs associated with developing or obtaining internal-use software. ASU 2018-15 is effective for public companies during interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. We adopted ASU 2018-15 effective January 1, 2020 on a prospective basis. The adoption is not expected to have a significant impact on our Consolidated Financial Statements. 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.

Discontinued Operations and Disposal Groups [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	Note 2 . Discontinued Operations On November 1, 2018, we completed the spin-off of Arcosa. Upon completion of the spin-off transaction, the accounting requirements for reporting Arcosa as a discontinued operation were met, and, accordingly, Arcosa's historical results have been reclassified to discontinued operations for the periods presented herein. In connection with the spin-off transaction, Trinity and Arcosa entered into various agreements to effect the distribution and provide a framework for their relationship after the separation, including a separation and distribution agreement, a transition services agreement, an employee matters agreement, a tax matters agreement, and an intellectual property matters agreement. Trinity is also party to certain commercial agreements with Arcosa entities. These agreements have various durations ranging between one and eighteen months. We have determined that the continuing cash flows generated by these agreements do not constitute significant continuing involvement in the operations of Arcosa. The amount billed for transition services provided under the above agreements was not material to our results of operations for the years ended December 31, 2019 and 2018 . We incurred $2.9 million , $36.3 million , and $14.2 million in spin-off related transaction costs during the years ended December 31, 2019 , 2018 , and 2017 , respectively, of which $2.9 million , $31.2 million , and $14.2 million are included in income from discontinued operations, net of income taxes in our Consolidated Statements of Operations. These costs primarily relate to the preparation of regulatory filings, investment banking fees, professional fees associated with various legal, accounting, and tax matters related to the spin-off, and other separation activities within the finance, tax, legal, and information technology functions. Arcosa is a stand-alone public company that separately reports its financial results. Due to differences between the basis of presentation for discontinued operations and the basis of presentation as a stand-alone company, the financial results of Arcosa included within discontinued operations may not be indicative of the actual financial results of Arcosa as a stand-alone company. The following is a summary of operating results included in income (loss) from discontinued operations for the years ended December 31, 2019 , 2018 , and 2017 : Year Ended December 31, 2019 2018 2017 (in millions) Revenues $ — $ 1,042.0 $ 1,265.4 Cost of revenues — 840.8 971.0 Selling, engineering, and administrative expenses 4.1 116.8 116.3 Other (income) expense — (0.4 ) 1.6 Income (loss) from discontinued operations before income taxes (4.1 ) 84.8 176.5 Provision (benefit) for income taxes (1.0 ) 30.7 73.1 Income (loss) from discontinued operations, net of income taxes $ (3.1 ) $ 54.1 $ 103.4

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Derivative Instruments We use derivative instruments to mitigate the impact of changes in interest rates, both in anticipation of future debt issuances and to offset interest rate variability of certain floating rate debt issuances outstanding. We also may use derivative instruments to mitigate the impact of changes in natural gas and diesel fuel prices and 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 loss ("AOCL") as a separate component of stockholders' equity and reclassified into earnings in the period during which the hedged transaction affects earnings. We continuously monitor our derivative positions and the credit ratings of our counterparties and do not anticipate losses due to non-performance.

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 as Level 1 in the fair value hierarchy are summarized below: Level 1 December 31, 2019 December 31, 2018 (in millions) Assets: Cash equivalents $ 57.9 $ 124.9 Restricted cash 111.4 171.6 Total assets $ 169.3 $ 296.5 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 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 liabilities measured as Level 2 in the fair value hierarchy are summarized below: Level 2 December 31, 2019 December 31, 2018 (in millions) Assets: Foreign currency hedge (1) $ 1.2 $ — Total assets $ 1.2 $ — Liabilities: Interest rate hedge (2) $ 28.0 $ 12.9 Total liabilities $ 28.0 $ 12.9 (1) Included in other assets in our Consolidated Balance Sheets. (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, 2019 and 2018 , we have no assets measured as Level 3 in the fair value hierarchy, except as described in Note 10 and Note 11 . See Note 8 for the estimated fair values of our debt instruments. The fair values of all other financial instruments are estimated to approximate carrying value.

Segment Information [Abstract]
Schedule of Segment Reporting Information, by Segment [Table Text Block]	Note 4 . Segment Information We report our operating results in three principal business segments: (1) the Railcar Leasing and Management Services Group, which owns and operates a fleet of railcars and provides third-party fleet leasing, management, and administrative services; (2) the Rail Products Group, which manufactures and sells railcars and related parts and components, and provides railcar maintenance and modification services; and (3) All Other. The All Other segment includes our highway products business; our logistics business; legal, environmental, and maintenance costs associated with non-operating facilities; and other peripheral businesses. Gains and losses from the sale of property, plant, and equipment are included in the operating profit of each respective segment. Our Chief Operating Decision Maker ("CODM") regularly reviews the operating results of our reportable segments in order to assess performance and allocate resources. 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 and are reflected in "Eliminations — Lease Subsidiary" in the tables below. 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.

Partially-Owned Leasing Subsidiaries [Abstract]
Noncontrolling Interest Disclosure [Text Block]	Note 5 . Partially-Owned Leasing Subsidiaries Through our wholly-owned subsidiary, Trinity Industries Leasing Company (“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, 2019 , the carrying value of our investment in TRIP Holdings and RIV 2013 totaled $186.5 million . Our weighted average ownership interest in TRIP Holdings and RIV 2013 is 38% while the remaining 62% weighted average interest is owned by third-party, investor-owned funds. The investment in our partially-owned leasing subsidiaries is 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. These wholly-owned subsidiaries are TRIP Master Funding (wholly-owned by TRIP Holdings) and Trinity Rail Leasing 2012 LLC ("TRL-2012", wholly-owned by RIV 2013). Railcar purchases by these subsidiaries were funded by secured borrowings and capital contributions from TILC and third-party equity investors. TILC is the contractual servicer for TRIP Master Funding and TRL-2012, 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 TRIP Master Funding and TRL-2012 may only be used to satisfy the particular subsidiary's liabilities, and the creditors of each of TRIP Master Funding and TRL-2012 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 TRIP Master Funding and TRL-2012 and has the potential to earn certain incentive fees. TILC and the third-party equity investors have commitments to provide additional equity funding to TRIP Holdings that are scheduled to expire in May 2021 , contingent upon certain returns on investment in TRIP Holdings and other conditions being met. There are no remaining equity commitments with respect to RIV 2013. See Note 8 regarding the debt of TRIP Holdings and RIV 2013 and their respective subsidiaries.

(3) Property disposition losses during the year ended December 31, 2018 included a non-cash charge of $12.6 million associated with our election to forego the early purchase options contained in certain lease agreements. During the years ended December 31, 2019 , 2018 , and 2017 , information related to the sales of leased railcars is as follows: Year Ended December 31, 2019 2018 2017 (in millions) Sales of leased railcars: Railcars owned one year or less at the time of sale (1) $ 360.7 $ 113.9 $ 99.6 Railcars owned more than one year at the time of sale 205.7 230.5 360.7 $ 566.4 $ 344.4 $ 460.3 Operating profit on sales of leased railcars: Railcars owned one year or less at the time of sale $ 41.4 $ 21.5 $ 19.7 Railcars owned more than one year at the time of sale 50.5 50.4 83.5 $ 91.9 $ 71.9 $ 103.2 Operating profit margin on sales of leased railcars: Railcars owned one year or less at the time of sale 11.5 % 18.9 % 19.8 % Railcars owned more than one year at the time of sale 24.6 % 21.9 % 23.1 % Weighted average operating profit margin on sales of leased railcars 16.2 % 20.9 % 22.4 % (1) Includes revenues associated with sales-type leases of $160.5 million for the year ended December 31, 2019 . Railcar Leasing Portfolio. The Leasing Group's Equipment consists primarily of railcars leased by third parties. The Leasing Group purchases equipment manufactured predominantly by the Rail Products Group and enters into lease contracts with third parties with terms generally ranging between one year and ten years , although certain leases entered into in prior periods had lease terms of up to twenty years . The Leasing Group primarily enters into operating leases. Future contractual minimum rental revenues on operating leases related to our wholly-owned and partially-owned subsidiaries are as follows: 2020 2021 2022 2023 2024 Thereafter Total (in millions) Future contractual minimum rental revenue $ 560.0 $ 445.8 $ 342.6 $ 241.5 $ 153.5 $ 268.0 $ 2,011.4 Debt. Wholly-owned subsidiaries. The Leasing Group’s debt at December 31, 2019 consisted primarily of non-recourse debt. As of December 31, 2019 , Trinity’s wholly-owned subsidiaries included in the Leasing Group held equipment with a net book value of $4,501.2 million which is pledged solely as collateral for Leasing Group debt held by those subsidiaries. The net book value of unpledged equipment at December 31, 2019 was $1,303.5 million . See Note 8 for more information regarding the Leasing Group debt. Partially-owned subsidiaries. Debt owed by TRIP Holdings and RIV 2013 and their respective subsidiaries is nonrecourse to Trinity and TILC. Creditors of each of TRIP Holdings and RIV 2013 and their respective subsidiaries have recourse only to the particular subsidiary's assets. TRIP Master Funding equipment with a net book value of $1,246.1 million is pledged as collateral for the TRIP Master Funding debt. TRL-2012 equipment with a net book value of $540.6 million is pledged solely as collateral for the TRL-2012 secured railcar equipment notes. See Note 5 for a description of TRIP Holdings and RIV 2013. Off Balance Sheet Arrangements. In prior years, the Leasing Group completed a series of financing transactions whereby railcars were sold to one or more separate independent owner trusts (“Trusts”). Each of the Trusts financed the purchase of the railcars with a combination of debt and equity. In each transaction, the equity participant in each of the respective Trusts was considered to be the primary beneficiary of the Trust; and therefore, the accounts of the Trusts, including the debt related to each of the Trusts, were not included as part of the Consolidated Financial Statements. The Leasing Group, through wholly-owned, qualified subsidiaries, leased railcars from the Trusts under operating leases with terms of twenty-two years , and subleased the railcars to independent third-party customers under shorter term operating lease agreements. The terms of the operating lease agreements between the subsidiaries and the remaining Trusts provided the Leasing Group with the option to purchase, at a predetermined fixed price, certain railcars from the remaining Trusts in 2019. On January 14, 2019, we completed the purchase for a purchase price of $218.4 million . As a result, 6,779 railcars previously under lease are now wholly-owned by our Leasing Group. The future contractual minimum rental revenues associated with these railcars are included in the table above. Operating Lease Obligations. Future amounts due as well as future contractual minimum rental revenues related to the Leasing Group's railcar operating lease obligations are as follows: 2020 2021 2022 2023 2024 Thereafter Total (in millions) Future operating lease obligations $ 9.8 $ 8.2 $ 7.5 $ 5.5 $ 2.3 $ 0.9 $ 34.2 Future contractual minimum rental revenues $ 8.1 $ 6.1 $ 4.5 $ 2.2 $ 0.5 $ 0.3 $ 21.7 Operating lease obligations totaling $2.9 million are guaranteed by Trinity Industries, Inc. and certain subsidiaries. The Leasing Group also has future amounts due for operating lease obligations related to office space of approximately $2.4 million , which is excluded from the table above.

The estimated fair values of our 2006, 2009, 2010, 2012, 2018, and 2019 secured railcar equipment notes, TRIHC 2018 LLC ("TRIHC 2018"), and TRIP Rail Master Funding LLC (“TRIP Master Funding”) secured railcar equipment notes are based on our estimate of their fair value as of December 31, 2019 and December 31, 2018 using unobservable input values provided by a third party (Level 3 inputs). The respective carrying values of our revolving credit facility, TILC warehouse facility, and 2017 promissory notes approximate fair value because the interest rate adjusts to the market interest rate. Revolving Credit Facility — We have a $450.0 million unsecured corporate revolving credit facility that matures in November 2023. Additionally, we are permitted to increase the amount of the commitments under the revolving credit facility by an aggregate amount not to exceed $200.0 million , subject to certain conditions, including the agreement of existing lenders to increase their commitments or by obtaining commitments from one or more new lenders. During the year ended December 31, 2019 , we had total borrowings of $1.0 billion and total repayments of $875.0 million under the revolving credit facility, with a remaining outstanding balance of $125.0 million as of December 31, 2019 . Additionally, we had outstanding letters of credit issued in an aggregate principal amount of $35.5 million , leaving $289.5 million available for borrowing as of December 31, 2019 . The outstanding letters of credit as of December 31, 2019 are scheduled to expire in July 2020. Our letters of credit obligations support our various insurance programs and generally renew by their terms each year. The revolving credit facility bears interest at a variable rate based on LIBOR or an alternate base rate at the time of the borrowing and Trinity’s leverage as measured by a consolidated total indebtedness to consolidated EBITDA ratio, and was initially set at LIBOR plus 1.25% ( 1.50% as of December 31, 2019 ). A commitment fee accrues on the average daily unused portion of the revolving facility at the rate of 0.175% to 0.30% ( 0.20% as of December 31, 2019 ). 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, 2019 , 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 2024 — In September 2014, we issued $400.0 million aggregate principal amount of 4.55% senior notes due October 2024. Interest on the Senior Notes is payable semiannually commencing April 1, 2015. The Senior Notes rank senior to existing and future subordinated debt, including our Notes and rank equal to existing and future senior indebtedness, including our revolving credit facility. The Senior Notes are subordinated to all our existing and future secured debt to the extent of the value of the collateral securing such indebtedness.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Note 9 . Income Taxes The components of the provision (benefit) for income taxes from continuing operations are as follows: Year Ended December 31, 2019 2018 2017 (in millions) Current: Federal $ (6.0 ) $ (19.1 ) $ (61.1 ) State 6.6 (1.5 ) (1.1 ) Foreign 6.1 5.3 4.5 Total current 6.7 (15.3 ) (57.7 ) Deferred: Federal Effect of Tax Cuts and Jobs Act — (5.9 ) (476.2 ) Other 44.0 49.1 121.9 44.0 43.2 (354.3 ) State 12.3 14.7 (2.8 ) Foreign (1.5 ) — — Total deferred 54.8 57.9 (357.1 ) Provision (benefit) $ 61.5 $ 42.6 $ (414.8 ) The provision for income taxes from continuing operations results in effective tax rates that differ from the statutory rates. The following is a reconciliation between the statutory U.S. federal income tax rate and our effective income tax rate on income before income taxes: Year Ended December 31, 2019 2018 2017 Statutory rate 21.0 % 21.0 % 35.0 % State taxes 2.2 2.3 (1.9 ) Foreign branch taxes 1.2 2.9 — Executive compensation limitations 1.2 0.9 — Interest expense limitations from partially-owned subsidiaries 1.0 1.3 — Noncontrolling interest in partially-owned subsidiaries 0.1 (0.5 ) (2.0 ) Equity compensation (0.8 ) (1.4 ) 0.8 Changes in state laws and apportionment 4.3 5.2 (0.5 ) Effect of Tax Cuts and Jobs Act — (3.9 ) (243.7 ) Changes in valuation allowances and reserves — 1.6 1.9 Settlements with tax authorities — — (2.1 ) Other, net 0.4 (1.3 ) 0.3 Effective rate 30.6 % 28.1 % (212.2 )% The effective tax rate is based upon the U.S. statutory rate of 21.0% , 21.0% , and 35.0% for the years ended December 31, 2019 , 2018 , and 2017 , respectively. For the year ended December 31, 2019 , the difference between the U.S. statutory rate and effective tax rate is primarily due to state income tax expense, foreign branch taxes, and changes in state tax laws and apportionment. The changes in apportionment include the effects of a one-time, non-cash, deferred tax impact related to our planned Maintenance Services expansion into a new Midwest facility of $9.7 million . For the year ended December 31, 2018, the difference between the U.S. statutory tax rate and the effective tax rate was primarily attributed to state taxes, foreign branch taxes, the impact changes in state apportionment and state tax laws, and the final accounting for the effects of the Tax Cuts and Jobs Act (the "Tax Act") that was enacted on December 22, 2017. For the year ended December 31, 2017, the difference between the statutory tax rate and effective tax rate was primarily attributable to the enactment of the Tax Act. See Note 5 for a further explanation of activities with respect to our partially-owned leasing subsidiaries. The Tax Act reduced the U.S. federal corporate income tax rate from 35.0% to 21.0% . The Tax Act also required certain calendar year companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that had previously not been taxed in the U.S. as part of their 2017 tax return filing. Beginning with the 2018 tax year, the Tax Act subjects certain earnings of foreign subsidiaries to U.S. taxation; in 2018, the Company did not incur the new U.S. tax on the income of its foreign subsidiaries. For the year ended December 31, 2017, we recognized a provisional net benefit of $476.2 million . During the year ended December 31, 2018, we finalized the accounting for the enactment of the Tax Act and recorded an additional benefit of $5.9 million , primarily as a result of truing up deferred taxes and our calculation of the one-time transition tax. Income (loss) before income taxes for the years ended December 31, 2019 , 2018 , and 2017 was $201.1 million , $139.8 million , and $186.2 million , respectively, for U.S. operations, and $(0.4) million , $11.8 million , and $9.2 million , respectively, for foreign operations, principally Mexico and Canada. 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: December 31, 2019 2018 (in millions) Deferred tax liabilities: Depreciation, depletion, and amortization $ 913.4 $ 718.4 Partially-owned subsidiaries basis difference 144.7 131.7 Right-of-use assets 10.0 — Total deferred tax liabilities 1,068.1 850.1 Deferred tax assets: Workers compensation, pensions, and other benefits 3.1 5.7 Warranties and reserves 4.5 8.1 Equity items 46.1 34.0 Tax loss carryforwards and credits 229.0 65.5 Inventory 5.1 8.9 Accrued liabilities and other 9.7 9.1 Lease liabilities 10.0 — Total deferred tax assets 307.5 131.3 Net deferred tax liabilities before valuation allowances 760.6 718.8 Valuation allowances 19.5 15.1 Net deferred tax liabilities before reserve for uncertain tax positions 780.1 733.9 Deferred tax assets included in reserve for uncertain tax positions (1.0 ) (2.3 ) Adjusted net deferred tax liabilities $ 779.1 $ 731.6 At December 31, 2019 , we had $940.5 million of federal consolidated net operating loss carryforwards and $13.2 million of tax-effected state loss carryforwards remaining. $18.9 million of the federal net operating loss carryforwards was acquired as part of an acquisition of a company in 2010 and is subject to limitations on the amount that can be utilized in any one tax year. The acquired federal net operating loss carryforwards are due to expire in 2028 and 2029. The federal net operating loss generated in the current year can be carried forward indefinitely. We have established a valuation allowance for federal, state, and foreign tax operating losses and credits that we have estimated may not be realizable. Taxing authority examinations We have settled our 2015 and 2016 tax years and received partial acceptance of our 2017 and 2018 tax years, pending final review of items related to the spin-off of Arcosa. The 2014-2019 tax years remain open. Our subsidiaries in Mexico file separate tax returns and are subject to examination by taxing authorities at different times. The entities statutes of limitations are open for their 2014 tax years and forward. Unrecognized tax benefits The change in unrecognized tax benefits for the years ended December 31, 2019 , 2018 , and 2017 was as follows: Year Ended December 31, 2019 2018 2017 (in millions) Beginning balance $ 8.1 $ 7.0 $ 20.7 Additions for tax positions of prior years — 3.0 4.5 Reductions for tax positions of prior years — (0.3 ) — Settlements (5.8 ) (1.5 ) (17.2 ) Expiration of statute of limitations — (0.1 ) (1.0 ) Ending balance $ 2.3 $ 8.1 $ 7.0 Settlements during the years ended December 31, 2019 and 2018 were due to the resolution of state audits. Settlements for the year ended December 31, 2017 were due to the Internal Revenue Service's ("IRS") resolution of our 2006-2009 tax years. Expiration of statutes of limitations during the years ended December 31, 2018 and 2017 relate to the 2013 and 2012 federal tax return, respectively, as well as some state statutes. The total amount of unrecognized tax benefits including interest and penalties at December 31, 2019 and 2018 , that would affect our effective tax rate if recognized, was $4.0 million and $9.4 million , respectively. Trinity 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, 2019 and 2018 was $2.7 million and $3.7 million , respectively. Income tax expense for the years ended December 31, 2019 , 2018 , and 2017 included a decrease of $1.0 million , an increase of $0.5 million , and a decrease of $3.3 million , respectively, with regard to interest expense and penalties related to uncertain tax positions.

Defined Benefit Plan Disclosure [Line Items]
Pension and Other Postretirement Benefits Disclosure [Text Block]	Note 10 . Employee Retirement Plans We sponsor defined benefit plans and defined contribution profit sharing plans that provide retirement income and death benefits for eligible employees. The annual measurement date of the benefit obligations, fair value of plan assets, and funded status is December 31. Planned Pension Plan Termination On September 4, 2019, our Board of Directors approved the termination of the Trinity Industries, Inc. Consolidated Pension Plan (the "Pension Plan"), effective December 31, 2019. Except for retirees currently receiving payments under the Pension Plan, participants will have the choice of receiving a single lump sum payment or an annuity from a highly-rated insurance company that will pay and administer future benefit payments. The Pension Plan is expected to be settled between late 2020 and early 2021, subject to required governmental approvals, and would then result in the Company no longer having any remaining funded pension plan obligations. Upon settlement, we expect to incur pre-tax pension settlement charges totaling between $155 million and $185 million . The settlement charges will be recognized in our Statement of Operations in two phases, with the first charge to be recognized when payments are made to those participants electing to receive a lump sum distribution, and the second charge to be recognized when the annuity contracts are purchased to settle all remaining outstanding pension obligations. The range of settlement charges includes: (1) a non-cash charge for the recognition of all pre-tax actuarial losses accumulated in AOCL related to the Pension Plan, which totaled approximately $170.1 million ( $131.2 million , net of tax) as of December 31, 2019 ; and (2) a potential additional cash contribution to settle all of the Pension Plan’s obligations, which is not expected to exceed $15.0 million . The actual amount of the settlement charges and any potential cash contribution will depend on interest rates, Pension Plan asset returns, the lump-sum election rate, and other factors. In anticipation of the planned settlement of the Pension Plan, our benefit obligations as of December 31, 2019 were valued based on the amounts expected to be required to settle these obligations, which included assumptions regarding the portion of obligations expected to be settled through lump sum payments or annuity contracts, and the current estimates of the cost to purchase such annuity contracts. Actuarial assumptions Year Ended December 31, 2019 2018 2017 Assumptions used to determine benefit obligations at the annual measurement date were: Obligation discount rate 2.73% 4.45% 3.79% Compensation increase rate (1) n/a n/a 4.00% Assumptions used to determine net periodic benefit costs were: Obligation discount rate 4.45% 3.79% 4.34% Long-term rate of return on plan assets 4.90% 5.65% 6.25% Compensation increase rate (1) n/a n/a 4.00% (1) The compensation increase rate pertains to a plan associated with our Former Inland Barge Group. The Inland Barge Group was transferred to Arcosa in connection with the spin-off, but Trinity retained the pension plan. Effective as of November 1, 2018, all participants in this plan have been granted the maximum benefit allowed under the plan; therefore, the compensation increase rate is not applicable. The obligation discount rate assumption is determined by deriving a single discount rate from a theoretical settlement portfolio of high quality corporate bonds sufficient to provide for the plans' projected benefit payments. The expected long-term rate of return on the plans' assets is an assumption reflecting the anticipated weighted average rate of earnings on the portfolio over the long-term. To arrive at this rate, estimates were developed based upon the anticipated performance of the plans' assets. Substantially all of the accrued benefits of our remaining pension plans were frozen in 2009, with all qualified pension plans frozen as of December 31, 2019. Components of Net Periodic Benefit Cost and Other Retirement Expenses Year Ended December 31, 2019 2018 2017 (in millions) Expense Components Service cost $ 0.1 $ 0.1 $ 0.2 Interest 19.7 18.3 19.6 Expected return on plan assets (23.0 ) (27.4 ) (27.2 ) Amortization of actuarial loss 4.6 4.8 4.9 Other — 0.6 — Net periodic benefit cost 1.4 (3.6 ) (2.5 ) Profit sharing 11.0 11.1 7.7 Net expense $ 12.4 $ 7.5 $ 5.2 The expected return on plan assets is based on the plan assets' fair value. Amortization of actuarial loss is determined using the corridor method. Under the corridor method, unamortized actuarial gains or losses in excess of 10% of the greater of the projected benefit obligation or the fair value of plan assets as of the beginning of the plan year are amortized, for frozen plans, over the average expected remaining lifetime of frozen and inactive participants.

Actuarial losses included in AOCL and expected to be recognized in net periodic pension cost for the year ended December 31, 2020 are $6.0 million ( $4.6 million net of related income taxes). Amortization of prior service cost included in AOCL and expected to be recognized in net periodic pension cost for the year ended December 31, 2020 is $1.2 million ( $0.9 million net of related income taxes). Plan assets Our pension plan investment strategies have been developed as part of a comprehensive asset/liability management process that considers the relationship between both the assets and liabilities of the plans for the purpose of providing the capital assets necessary to meet the financial obligations made to participants of our pension plans. These strategies consider not only the expected risk and returns on the plans' assets, but also the actuarial projections of liabilities, projected contributions, and funded status. Our investment policy statement allocates our pension plan assets into two portfolios as follows: • Liability hedging portfolio — The objective of the liability hedging portfolio is to match the characteristics of the pension plans' liabilities. This portfolio consists of fixed income holdings which are generally investment grade. • Growth portfolio — The objective of the growth portfolio is to focus upon total return with an acceptable level of risk. This portfolio is heavily weighted toward U.S. equities with a lesser exposure to international equities, domestic real estate investment trusts, U.S. high yield and emerging market sovereign debt. The target allocation between these two portfolios varies based on the pension plans' percentage of projected benefit obligations funded status. The range of target asset allocations has been determined after giving consideration to the expected returns of each asset category within the two portfolios, the expected performance of each asset category, the volatility of asset returns over time, and the complementary nature of the asset mix within the portfolio. The principal pension investment strategies include asset allocation and active asset management within approved guidelines. These assets are managed by an investment advisor. Following our Board of Directors approval to terminate our Pension Plan, a new investment allocation strategy was implemented to protect the funded status of the plan assets. The target allocation at December 31, 2019 is 100% liability hedging portfolio, compared to 90% liability hedging portfolio and 10% growth portfolio at December 31, 2018. The target and actual allocations of the plans' assets at December 31, 2019 are as follows: Target December 31, Cash and cash equivalents — % 3 % Liability hedging portfolio 100 % 92 % Growth portfolio — % 5 % Total 100 % 100 % The estimated fair value of the plans' assets at December 31, 2019 and 2018 , indicating input levels used to determine fair value are as follows: Fair Value Measurement as of December 31, 2019 (in millions) Level 1 Level 2 Level 3 Total Temporary cash investments $ 13.5 $ — $ — $ 13.5 Fixed Income — Government and agencies — 121.7 — 121.7 Fixed Income — Corporate — 370.5 — 370.5 Fixed Income — Asset-backed securities — 2.2 — 2.2 Fixed Income — Collateralized mortgage-backed — 4.1 — 4.1 Equity common trust funds — 29.1 — 29.1 Debt common trust funds — — 7.4 7.4 $ 13.5 $ 527.6 $ 7.4 $ 548.5 Fair Value Measurement as of December 31, 2018 (in millions) Level 1 Level 2 Level 3 Total Temporary cash investments $ 14.0 $ — $ — $ 14.0 Fixed Income — Government and agencies — 77.1 — 77.1 Fixed Income — Corporate — 309.1 — 309.1 Fixed Income — Collateralized mortgage-backed — 2.1 — 2.1 Equity common trust funds — 69.7 — 69.7 Debt common trust funds — — 6.7 6.7 $ 14.0 $ 458.0 $ 6.7 $ 478.7 The pension plans' assets are valued at fair value. The following is a description of the valuation methodologies used in determining fair value, including the general classification of such instruments pursuant to the valuation hierarchy as described further in Note 3 : Temporary cash investments — These investments consist of U.S. dollars held in master trust accounts with the trustee. These temporary cash investments are classified as Level 1 instruments. Fixed Income — Government and agencies — These investments consist primarily of U.S. treasury bonds and notes, U.S. treasury inflation protected securities, U.S. government agency debt, municipal bonds, and other global government bonds. The fair value of these securities is based on quoted market prices when available or is based on yields currently available on comparable securities or on an industry valuation model, which maximizes observable inputs. These securities are categorized as Level 2 instruments. Fixed Income — Corporate — These investments consist of U.S. and global corporate bonds and notes. The fair value of these securities is based on yields currently available on comparable securities of issuers with similar credit ratings. When quoted prices are not available for identical or similar debt instruments, the fair value is based upon an industry valuation model, which maximizes observable inputs. These securities are categorized as Level 2 instruments. Fixed Income — Asset-backed securities — Asset-backed securities are valued using quotes from independent pricing vendors based on recent trading activity and other relevant information, including market interest rate curves, referenced credit spreads, and estimated prepayment rates, where applicable. These securities are categorized as Level 2 instruments. Fixed Income — Collateralized mortgage-backed — Mortgage-backed securities are valued using quotes from independent pricing vendors based on recent trading activity and other relevant information, including market interest rate curves, referenced credit spreads, and estimated prepayment rates, where applicable. These securities are categorized as Level 2 instruments. Common trust funds — Common trust funds are comprised of shares or units in commingled funds that are not publicly traded. The underlying assets in these funds are publicly traded on exchanges and price quotes for the assets held by these funds are readily available. Holdings of common trust funds are classified as a combination of Level 2 and Level 3 instruments. Cash flows Employer contributions for the year ending December 31, 2020 are expected to be $1.1 million for the defined benefit plans, which excludes any potential cash contribution that may be required to settle the Company's pension plan obligations as described above, compared to $1.1 million contributed during 2019 . Employer contributions to the 401(k) plan and the Supplemental Profit Sharing Plan for the year ending December 31, 2020 are expected to be $11.4 million compared to $10.6 million contributed during 2019 . Benefit payments for our defined benefit plans are expected to be approximately $225 million in 2020 and approximately $336 million in 2021, which reflects the impact of the Pension Plan termination. Participants in the 401(k) plan are eligible to receive future retirement benefits through a company-funded annual retirement contribution provided through the Profit Sharing Plan for Employees of Trinity Industries, Inc. and Certain Affiliates. The contribution ranges from one to three percent of eligible compensation based on service. Both the annual retirement contribution and the company matching contribution are discretionary, requiring board approval, and are made annually with the investment of the funds directed by the participants.

Restructuring Charges [Abstract]
Restructuring and Related Activities Disclosure [Text Block]	Note 11 . Restructuring Activities In November 2019, we approved a restructuring plan to resize certain resources, reduce stranded costs, and better align support services with our rail-focused strategy. As part of the restructuring program, we eliminated positions across multiple locations and functions, including certain corporate and operational support functions. Other restructuring actions associated with this plan are expected to be substantially completed in 2020. During the year ended December 31, 2019, we recorded total restructuring charges of $14.7 million , consisting of approximately $3.8 million in cash charges for severance costs and approximately $10.9 million of non-cash charges, primarily from write-downs of assets associated with our non-operating facilities that will no longer be utilized as we execute our rail-focused strategy. The final liquidation of our non-operating facilities could result in the disposition of certain assets, which were not included in the fourth quarter 2019 restructuring charge, at amounts in excess of their carrying value. As we continue to reposition the organization, it is possible that we will engage in additional restructuring activities in 2020. The following table sets forth the restructuring activity and balance of the restructuring liability, which is included in other liabilities in our Consolidated Balance Sheet: Accrued charges as of December 31, 2018 Charges and adjustments Payments Accrued charges as of December 31, 2019 (in millions) Cash charges: Employee severance costs $ — $ 3.8 $ (0.4 ) $ 3.4 $ — $ 3.8 $ (0.4 ) $ 3.4 Non-cash charges: Write-down of assets $ 10.9 Total restructuring activities $ 14.7 Although restructuring activities are not allocated to our reportable segments, the following table summarizes the restructuring activities by reportable segment: Year Ended December 31, 2019 Employee Severance Costs Write-down of Assets Total (in millions) Railcar Leasing and Management Services Group $ 0.2 $ — $ 0.2 Rail Products Group 0.7 — 0.7 All Other 0.5 10.9 11.4 Corporate 2.4 — 2.4 Total restructuring activities $ 3.8 $ 10.9 $ 14.7

Common Stock and Stock-based Compensation [Abstract]
Shareholders' Equity and Share-based Payments [Text Block]	Note 13 . Common Stock and Stock-Based Compensation Stockholders' Equity In December 2017, our Board of Directors authorized a $500 million share repurchase program effective January 1, 2018 through December 31, 2019. On November 16, 2018, we entered into an accelerated share repurchase program (the "ASR Program") to repurchase $350 million of the Company's common stock. The $350 million notional value of the ASR Program represented the entire remaining amount that was available to us under the share repurchase program that was in effect at that time. The ASR Program was completed in March 2019. In March 2019 , our Board of Directors authorized a new share repurchase program effective March 7, 2019 through December 31, 2020 . The new share repurchase program authorizes the Company to repurchase up to $350.0 million of its common stock, not to exceed 13.7 million shares. The share repurchase program is designed to meet certain IRS safe harbor guidelines associated with our spin-off of Arcosa, which was completed on November 1, 2018. During the years ended December 31, 2019 , 2018 , and 2017 , we repurchased 13.7 million , 17.2 million , and 2.8 million shares, respectively, at a cost of approximately $294.7 million , $430.1 million , and $85.4 million , respectively. The total for the year ended December 31, 2019 includes 2.6 million shares at a cost of approximately $70.0 million representing the final settlement of the ASR Program, which was funded in November 2018 but a portion of which remained outstanding as of December 31, 2018. As of December 31, 2019 , the Company had a remaining authorization to repurchase up to $125.3 million , not to exceed 2.6 million shares, of its common stock under the current repurchase program. Stock-Based Compensation Stock Award Plans Our 2004 Fourth Amended and Restated Stock Option and Incentive Plan (the "Plan”) provides for awarding 20,150,000 (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, 2019 , a total of 2,737,464 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. Options become exercisable in various percentages over periods ranging up to five years. Stock-Based Compensation Expense The cost of employee services received in exchange for awards of equity instruments is referred to as share-based compensation and is based on the grant date fair-value of those awards. Stock-based compensation includes compensation expense, recognized over the applicable vesting periods, for share-based awards. Stock-based compensation expense totaled $29.2 million , $29.3 million , and $24.6 million for the years ended December 31, 2019 , 2018 , and 2017 , respectively. The income tax benefit related to stock-based compensation expense was $6.6 million , $7.7 million , and $14.5 million for the years ended December 31, 2019 , 2018 , and 2017 , respectively. Restricted Stock Restricted share awards consist of restricted stock and restricted stock units.

Certain restricted stock and restricted stock units vest in their entirety upon the 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. Restricted stock and restricted stock units granted to non-employee directors under the Plan generally vest one year from the grant date and are released at that time or upon completion of the directors' service to the Company. Expense related to restricted stock units issued to eligible employees under the Plan is recognized ratably over the vesting period, generally between three years and four years. Expense related to restricted stock awards granted to non-employee directors under the Plan is recognized ratably over the vesting period, generally one year. Forfeitures are recognized as a reduction to expense in the period in which they occur.

Earnings Per Common Share [Abstract]
Earnings Per Share [Text Block]	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 remaining after allocation to unvested restricted shares 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 1) the net impact of unvested RSAs and RSUs and 2) with respect to the years ended December 31, 2018 and 2017 , the dilutive impact of our then-outstanding convertible notes due 2036 (the "Convertible Notes"), which were converted and settled in cash during the second quarter of 2018. See Note 11 of our 2018 Annual Report on Form 10-K for further information regarding the settlement of the Convertible Notes. Total weighted average restricted shares were 5.5 million , 5.8 million , and 6.4 million shares for the years ended December 31, 2019 , 2018 , and 2017 , respectively.

Commitments and Contingencies [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Note 15 . Contingencies Highway products litigation We previously reported the filing of a False Claims Act (“FCA”) complaint in the United States District Court for the Eastern District of Texas, Marshall Division (“District Court”) styled Joshua Harman, on behalf of the United States of America, Plaintiff/Relator v. Trinity Industries, Inc., Defendant , Case No. 2:12-cv-00089-JRG (E.D. Tex.). In this case, in which the U.S. Government declined to intervene, the relator, Mr. Joshua Harman, alleged the Company violated the FCA pertaining to sales of the Company's ET-Plus® System, a highway guardrail end-terminal system (“ET Plus”). On October 20, 2014, a trial in this case concluded with a jury verdict stating that the Company and its subsidiary, Trinity Highway Products, LLC (“Trinity Highway Products”), “knowingly made, used or caused to be made or used, a false record or statement material to a false or fraudulent claim" and awarding $175.0 million in damages. On June 9, 2015 the District Court entered judgment on the verdict in the total amount of $682.4 million , comprised of $175.0 million in damages, which amount was automatically trebled under the FCA to $525.0 million plus $138.4 million in civil penalties and $19.0 million in costs and attorneys' fees. On September 29, 2017, the United States Court of Appeals for the Fifth Circuit ("Fifth Circuit") reversed the District Court’s $682.4 million judgment and rendered judgment as a matter of law in favor of the Company and Trinity Highway Products. On October 27, 2017, Mr. Harman filed a Petition for Rehearing En Banc in the Fifth Circuit, which was denied by the Fifth Circuit on November 14, 2017. On February 12, 2018, Mr. Harman, filed a petition for certiorari with the United States Supreme Court, seeking a review of the Fifth Circuit's decision. On January 7, 2019, the United States Supreme Court denied Mr. Harman's petition for certiorari. The denial of Mr. Harman's petition ends this action. State, county, and municipal actions Mr. Harman also has separate state qui tam actions currently pending pursuant to: the Virginia Fraud Against Taxpayers Act ( 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); the Tennessee False Claims Act ( State of Tennessee ex rel. Joshua M. Harman v. Trinity Industries, Inc., and Trinity Highway Products, LLC , Case No. 14C2652, in the Circuit Court for Davidson County, Tennessee); the Massachusetts False Claims Act ( Commonwealth of Massachusetts ex rel. Joshua M. Harman Qui Tam v. Trinity Industries, Inc. and Trinity Highway Products, LLC , Case No. 1484-CV-02364, in the Superior Court Department of the Trial Court); the New Jersey False Claims Act ( 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); and the California False Claims Act ( State of California ex rel. Joshua M. Harman Qui Tam v. Trinity Industries, Inc. and Trinity Highway Products, LLC , Case No. RG 14721864, in the Superior Court of California, Alameda County). In each of these cases, Mr. Harman alleged the Company violated the respective states' false claims act pertaining to sales of the ET Plus, and he is seeking damages, civil penalties, attorneys’ fees, costs and interest. Also, the respective states’ Attorneys General filed Notices of Election to Decline Intervention in all of these matters, with the exception of the Commonwealth of Virginia Attorney General, who intervened in the Virginia matter. Following the United States Supreme Court’s denial of Mr. Harman’s petition for certiorari, the stays have expired or been lifted by court order in all of the above-referenced state qui tam cases except Virginia. As previously reported, state qui tam actions filed by Mr. Harman in the states of Delaware, Florida, Georgia, Illinois, Indiana, Iowa, Minnesota, Montana, Nevada, and Rhode Island were dismissed. The Company believes these state qui tam lawsuits are without merit and intends to vigorously defend all allegations. Other states could take similar or different actions, and could be considering similar state false claims or other litigation against the Company. The Company has been served in a lawsuit filed November 5, 2015, titled Jackson County, Missouri, individually and on behalf of a class of others similarly situated vs. Trinity Industries, Inc. and Trinity Highway Products, LLC , Case No. 1516-CV23684 (Circuit Court of Jackson County, Missouri). The case is being brought by plaintiff for and on behalf of itself and all Missouri counties with a population of 10,000 or more persons, including the City of St. Louis, and the State of Missouri’s transportation authority. The plaintiff alleges that the Company and Trinity Highway Products did not disclose design changes to the ET Plus and these allegedly undisclosed design changes made the ET Plus allegedly defective, unsafe, and unreasonably dangerous. The plaintiff alleges product liability negligence, product liability strict liability, and negligently supplying dangerous instrumentality for supplier’s business purposes. The plaintiff seeks compensatory damages, interest, attorneys' fees and costs, and in the alternative plaintiff seeks a declaratory judgment that the ET Plus is defective, the Company’s conduct was unlawful, and class-wide costs and expenses associated with removing and replacing the ET Plus throughout Missouri. On December 6, 2017, the Court granted plaintiff's Motion for Class Certification, certifying a class of Missouri counties with populations of 10,000 or more persons, including the City of St. Louis and the State of Missouri's transportation authority that have or had ET Plus guardrail end terminals with 4-inch wide guide channels installed on roadways they own or maintain. A trial date has been scheduled in this case for April 27, 2020. The Company believes this lawsuit is without merit and intends to vigorously defend all allegations. While the financial impacts of these state, county, and municipal actions are currently unknown, they could be material. Based on information currently available to the Company and previously disclosed, including, but not limited to the significance of the successful completion of eight post-verdict crash tests of the ET Plus in 2015, the favorable findings and conclusions published in 2015 by two joint task forces of the Federal Highway Administration and the American Association of State Highway and Transportation Officials regarding the ET Plus end terminal system, the Fifth Circuit's unanimous panel opinion reversing the $682.4 million judgment and rendering judgment in favor of the Company, and the United States Supreme Court’s subsequent denial of Mr. Harman's petition for certiorari in the FCA case, we currently do not believe that a loss is probable in any one or more of the actions described under "State, county, and municipal actions," 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. Product liability cases The Company is currently defending product liability lawsuits in several different states that are alleged to involve the ET Plus as well as other products manufactured by Trinity Highway Products. 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". Shareholder class actions On January 11, 2016, the previously reported cases styled Thomas Nemky, Individually and On Behalf of All Other Similarly Situated v. Trinity Industries, Inc., Timothy R. Wallace, and James E. Perry , Case No. (2:15-CV-00732) (“Nemky”) and Richard J. Isolde, Individually and On Behalf of All Other Similarly Situated v. Trinity Industries, Inc., Timothy R. Wallace, and James E. Perry, Case No. (3:15-CV-2093) ("Isolde"), were consolidated in the District Court for the Northern District of Texas, with all future filings to be filed in the Isolde case. On May 11, 2016, the Lead Plaintiffs filed their Consolidated Complaint alleging defendants Trinity Industries, Inc., Timothy R. Wallace, James E. Perry, and Gregory B. Mitchell violated Section 10(b) of the Securities Exchange Act of 1934, Rule 10b-5 promulgated thereunder, and defendants Mr. Wallace and Mr. Perry violated Section 20(a) of the Securities Exchange Act of 1934 by making materially false and misleading statements and/or by failing to disclose material facts about Trinity's ET Plus and the FCA case styled Joshua Harman, on behalf of the United States of America, Plaintiff/Relator v. Trinity Industries, Inc., Defendant , Case No. 2:12-cv-00089-JRG (E.D. Tex.). The parties reached an agreement to settle all claims in this case without any admission of liability or fault for $7.5 million , and on September 23, 2019, entered into a Stipulation of Settlement. Defendants have denied and continue to deny specifically each and all of the claims and contentions alleged by Lead Plaintiffs in this case. The settlement is subject to final court approval. On September 24, 2019, Lead Plaintiffs filed with the Court an Unopposed Motion for Preliminary Approval of Settlement and Approval of Notice to the Class. On November 12, 2019, the Court entered an Order Preliminarily Approving Settlement and Providing for Notice and scheduled a settlement hearing on March 31, 2020. 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 $21.6 million to $35.3 million , which includes our rights in indemnity and recourse to third parties of approximately $15.2 million , which is recorded in Other Assets on our Consolidated Balance Sheet as of December 31, 2019 . This range includes any amounts related to the Highway Products litigation matters described above in the section titled “Highway products litigation.” At December 31, 2019 , total accruals of $23.0 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.

Guarantor Obligations [Line Items]
Condensed Financial Statements [Text Block]	Note 16 . Financial Statements for Guarantors of the Senior Notes Our Senior Notes are fully and unconditionally and jointly and severally guaranteed by certain of Trinity’s 100%-owned subsidiaries: Trinity Industries Leasing Company; Trinity North American Freight Car, Inc.; Trinity Rail Group, LLC; Trinity Tank Car, Inc.; Trinity Highway Products, LLC; and TrinityRail Maintenance Services, Inc. (collectively, the "Combined Guarantor Subsidiaries”). The Senior Notes indenture agreement includes customary provisions for the release of the guarantees by the Combined Guarantor Subsidiaries upon the occurrence of certain allowed events including the release of one or more of the Combined Guarantor Subsidiaries as guarantor under our revolving credit facility. See Note 8 . The Senior Notes are not guaranteed by any of our remaining 100%-owned subsidiaries or partially-owned subsidiaries (“Combined Non-Guarantor Subsidiaries”). On November 1, 2018, we amended our Credit Agreement and the Supplemental Indenture governing our Senior Notes to release Trinity Marine Products, Inc., Trinity Meyer Utility Structures LLC and Trinity Structural Towers, Inc. from their obligations as guarantors for the Credit Agreement and the Senior Notes effective upon completion of the Arcosa spin-off as these businesses were transferred to Arcosa in connection with the spin-off. Additionally, upon completion of the Arcosa spin-off, the accounting requirements for reporting Arcosa as a discontinued operation were met. Accordingly, we have recast the financial information included in the tables below for all periods presented to: 1) reflect the historical balances and operating results of Arcosa as discontinued operations, 2) reclassify the historical balances and operating results of Trinity Marine Products, Inc., Trinity Meyer Utility Structures LLC and Trinity Structural Towers, Inc., who were formerly guarantor subsidiaries and whose results were previously reflected in the guarantor column, to the non-guarantor column, and 3) include Trinity Highway Products, LLC in the guarantor column. Additionally, amounts previously reported have been restated to include TrinityRail Maintenance Services, Inc. as a Guarantor Subsidiary for all periods presented and to affect reallocations of certain corporate costs between the parent, guarantor, and non-guarantor columns for the year ended December 31, 2018. As of December 31, 2019 , assets held by the Combined Non-Guarantor Subsidiaries included $ 86.1 million of restricted cash that was not available for distribution to Trinity Industries, Inc. (“Parent”), $ 6,409.8 million of equipment securing certain non-recourse debt, and $ 136.0 million of assets located in foreign locations. As of December 31, 2018 , assets held by the Combined Non-Guarantor Subsidiaries included $ 132.9 million of restricted cash that was not available for distribution to the Parent, $ 5,316.2 million of equipment securing certain non-recourse debt, $ 67.5 million of equipment securing certain lease obligations held by the Combined Non-Guarantor Subsidiaries, and $ 116.0 million of assets located in foreign locations.

Note 1. Summary of Significant Accounting Policies Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The financial statements of Trinity Industries, Inc. and its consolidated subsidiaries (“Trinity,” “Company,” “we,” “our,” or "us") include the accounts of its wholly-owned subsidiaries and its partially-owned subsidiaries, TRIP Rail Holdings LLC ("TRIP Holdings") and RIV 2013 Rail Holdings LLC ("RIV 2013"), in which we have a controlling interest. All significant intercompany accounts and transactions have been eliminated.
Spin-Off Transaction [Policy Text Block]	Spin-off of Arcosa, Inc. Upon completion of the spin-off of Arcosa, Inc. ("Arcosa") on November 1, 2018, the accounting requirements for reporting Arcosa as a discontinued operation were met. Accordingly, Arcosa's results of operations are presented as discontinued operations for all periods in this Form 10-K. See Note 2 for further information related to the spin-off transaction.
Revenue from Contract with Customer [Policy Text Block]	Revenue Recognition 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. 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 Management Services Group In our Railcar Leasing and Management 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 de-recognize 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 on the Consolidated Balance Sheet. Interest income related to sales-type leases is recognized over the lease term using the effective interest method. Revenue is recognized from the sales of railcars from the lease fleet on a gross basis in leasing revenues and cost of revenues if the railcar has been owned for one year or less at the time of sale. Sales of railcars from the lease fleet owned for more than one year are recognized as a net gain or loss from the disposal of a long-term asset. Revenue from servicing and management agreements is recognized as each performance period occurs. 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. Rail Products Group Our railcar manufacturing business recognizes revenue when the customer has submitted its certificate of acceptance and legal title of the railcar has passed to the customer. Certain long-term contracts for the sales of railcars include price adjustments based on steel-price indices; this amount represents variable consideration for which we are unable to estimate the final consideration until the railcar is delivered, at which time the pricing becomes fixed. Within our maintenance services business, 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 $5.2 million and $10.2 million as of December 31, 2019 and 2018 , respectively, related to unbilled revenues recognized on repair and maintenance services that have been performed, but for which the entire project has not yet been completed. These contract assets are included within the Receivables, net of allowance line in our Consolidated Balance Sheets. All Other Our highway products business recognizes revenue when shipment has occurred and legal title of the product has passed to the customer. 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, 2019 and the percentage of the outstanding performance obligations as of December 31, 2019 expected to be delivered during 2020 : Unsatisfied performance obligations at December 31, 2019 Total Amount Percent expected to be delivered in 2020 (in millions) Rail Products Group: Products: External Customers $ 1,213.4 Leasing Group 619.1 $ 1,832.5 59 % Maintenance Services $ 44.8 100 % Railcar Leasing and Management Services Group $ 100.5 16 % The remainder of the unsatisfied performance obligations for the Rail Products Group is expected to be delivered through 2023 . Unsatisfied performance obligations for the Railcar Leasing and Management 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 railcars, as well as office buildings, manufacturing equipment, and office equipment. Our operating leases have remaining lease terms ranging from one year to forty 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, 2019 , we had no finance leases in which we were the lessee. The following table summarizes the impact of our operating leases on our Consolidated Financial Statements (in millions, except lease term and discount rate): Year Ended December 31, 2019 Consolidated Statement of Operations Operating lease expense $ 18.0 Short-term lease expense $ 4.1 December 31, 2019 Consolidated Balance Sheet Right-of-use assets (1) $ 44.2 Lease liabilities (2) $ 44.8 Weighted average remaining lease term 4.8 years Weighted average discount rate 4.1 % Year Ended December 31, 2019 Consolidated Statement of Cash Flows Cash flows from operating activities $ 18.0 Right-of-use assets recognized in exchange for new lease liabilites $ 10.3 (1) Included in other assets in our Consolidated Balance Sheet (2) Included in other liabilities in our Consolidated Balance Sheet Future contractual minimum operating lease liabilities will mature as follows (in millions): Leasing Group Non-Leasing Group Total 2020 $ 10.1 $ 3.9 $ 14.0 2021 8.6 2.8 11.4 2022 7.8 2.6 10.4 2023 5.9 2.2 8.1 2024 2.7 1.1 3.8 Thereafter 1.5 2.9 4.4 Total operating lease payments $ 36.6 $ 15.5 $ 52.1 Less: Present value adjustment (7.3 ) Total operating lease liabilities $ 44.8
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 , although certain leases entered into in prior periods had lease terms of up to twenty years . The majority of our fleet operates on leases that earn fixed monthly lease payments. 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 options to terminate within one year with certain notice requirements and early termination penalties. Our sales-type leases include an option for the lessee to purchase the leased railcars with certain notice. As of December 31, 2019 , non-Leasing Group operating leases 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 participating in active 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. The following table summarizes the impact of our leases on our Consolidated Statement of Operations (in millions): Year Ended December 31, 2019 Operating lease revenues $ 676.3 Variable operating lease revenues 50.5 Sales-type lease revenues 160.5 Interest income on sales-type lease receivables 2.4 Profit recognized at sales-type lease commencement 19.0 Future contractual minimum lease receivables for sales-type leases will mature as follows (in millions): 2020 $ 43.4 2021 131.8 2022 — 2023 — 2024 — Thereafter — Total $ 175.2 Less: Unearned interest income (20.7 ) Net investment in sales-type leases (1) $ 154.5 (1) Included in other assets in our Consolidated Balance Sheet Future contractual minimum revenues for operating leases will mature as follows (in millions): 2020 $ 568.1 2021 451.9 2022 347.1 2023 243.7 2024 154.0 Thereafter 268.3 Total $ 2,033.1
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 the amounts used for income tax purposes. 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 .
Concentration Risk, Credit Risk, Policy [Policy Text Block]	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 and investment grade, short-term debt instruments and limit the amount of credit exposure to any one commercial issuer. 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. As receivables are generally unsecured, we maintain an allowance for doubtful accounts based upon the expected collectibility of all receivables. Receivable balances determined to be uncollectible are charged against the allowance. The carrying values of cash, receivables, and accounts payable are considered to be representative of their respective fair values.
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 3 – 30 years Leasehold improvements The lesser of the term of the lease or 7 years Machinery and equipment 2 – 10 years Information systems hardware and software 2 – 5 years Railcars in our lease fleet Generally 35 years As of early 2020, we are finalizing an assessment of the estimated useful lives and salvage value assumptions for the railcars in our lease fleet. Based upon analysis of historical fleet data, review of industry standards, and consideration of certain economic factors by railcar type, we have determined that it is appropriate to revise the useful lives and salvage values of certain railcar types in our lease fleet. We believe that the revised useful lives reflect the estimated economic lives of the railcars in our lease fleet. The net impact of these changes, which will become effective January 1, 2020, is expected to result in a change in the weighted average useful life of railcars in our lease fleet from approximately 34 years to approximately 37 years . This change will be accounted for as a change in accounting estimate, which is required to be accounted for on a prospective basis. Based on the composition of the lease fleet as of December 31, 2019, we expect this change to result in a net decrease in annual depreciation expense of between $27 million and $33 million for the year ended December 31, 2020.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	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. Based on our evaluations, no impairment charges were determined to be necessary on assets held and used as of December 31, 2019 and 2018 .
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. The quantitative goodwill impairment test is a two-step process, with step one requiring the comparison of the reporting unit's estimated fair value with the carrying amount of its net assets. If necessary, step two of the impairment test determines the amount of goodwill impairment to be recorded when 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 three inputs, related to revenue and operating profit results, discount rates, terminal growth rates and exit multiples. As of December 31, 2019 and 2018 , our annual impairment test of goodwill was completed at the reporting unit level, and no impairment charges were determined to be necessary. The net book value of intangible assets totaled $18.7 million and $22.4 million as of December 31, 2019 and 2018 , respectively, and included finite-lived intangible assets of $16.2 million and $19.9 million , respectively, which are amortized over their estimated useful lives ranging from one year to twenty years . Based on our evaluations of intangible assets, no impairment charges were determined to be necessary as of December 31, 2019 and 2018 . Goodwill by segment is as follows: December 31, 2019 December 31, 2018 (in millions) Railcar Leasing and Management Services Group $ 1.8 $ 1.8 Rail Products Group 145.4 145.4 All Other 61.6 61.6 $ 208.8 $ 208.8
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	Restricted Cash Restricted cash consists of cash and cash equivalents held either as collateral for our non-recourse debt and lease obligations or as security for the performance of certain product sales agreements. As such, they are restricted in use.
Variable Interest Entity Disclosure [Text Block]	Investments in Affiliates We continuously evaluate our investments and other contractual arrangements with third party entities to determine if our variable interests are considered a variable interest entity ("VIE"). Consolidation is required for VIEs in which we are the primary beneficiary. We have determined that we are the primary beneficiary for TRIP Holdings and RIV 2013. At December 31, 2019 , the carrying value of our investment in TRIP Holdings and RIV 2013 totaled $186.5 million . For further information regarding our partially-owned leasing subsidiaries, see Note 5 of the Consolidated Financial Statements.
Equity Method Investments and Joint Ventures Disclosure [Text Block]	Other Investments We hold certain other investments for which we do not have a controlling financial interest but have a significant influence over the financial and operating policies. The carrying values of our equity method investments totaled approximately $3.8 million and $3.4 million as of December 31, 2019 and 2018 , respectively.
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.
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. The changes in the accruals for warranties for the years ended December 31, 2019 , 2018 , and 2017 are as follows: Year Ended December 31, 2019 2018 2017 (in millions) Beginning balance $ 7.4 $ 10.1 $ 12.0 Warranty costs incurred (3.8 ) (2.8 ) (4.8 ) Warranty originations and revisions 4.5 0.1 4.8 Warranty expirations — — (1.9 ) Ending balance $ 8.1 $ 7.4 $ 10.1
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency Transactions The functional currency of our Mexico operations is the United States dollar. Certain transactions in Mexico occur in currencies other than the United States dollar. The impact of foreign currency fluctuations on these transactions is recorded in other, net (income) expense in our Consolidated Statement 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 2019 ASU 2016-02 — In February 2016, the FASB issued ASU No. 2016-02, "Leases", ("ASC 842") which amended the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. ASC 842 is effective for public companies during interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. In July 2018, the FASB issued ASU No. 2018-11, which permitted entities to record the right-of-use asset and lease liability on the date of adoption, with no requirement to recast comparative periods. We adopted ASC 842 effective January 1, 2019 using the optional transition method of recognizing a cumulative-effect adjustment to the opening balance of retained earnings on January 1, 2019. Therefore, comparative financial information was not adjusted and continues to be reported under the prior lease accounting guidance in ASC 840. We elected the transition relief package of practical expedients, and as a result, we did not assess 1) whether existing or expired contracts contain embedded leases, 2) lease classification for any existing or expired leases, and 3) whether lease origination costs qualified as initial direct costs. We elected the short-term lease practical expedient by establishing an accounting policy to exclude leases with a term of 12 months or less, as well as the land easement practical expedient for maintaining our current accounting policy for existing or expired land easements. For qualifying operating leases in which we are the lessor, we do not separate lease components for our leased railcars from non-lease components, which are comprised of stand-ready maintenance obligations. We did not elect the practical expedient to use hindsight in determining a lease term and impairment of right-of-use assets at the adoption date. Upon adoption, we recognized right-of-use assets and corresponding lease liabilities of $47.0 million and $48.3 million , respectively, in our Consolidated Balance Sheet based on the present value of future minimum lease payments under operating leases for which we are the lessee. This excluded the impact of railcars that were previously under operating leases as of January 1, 2019 but which were purchased on January 14, 2019 and are now wholly-owned by our Leasing Group. Additionally, we recorded an adjustment to opening retained earnings of $17.7 million ( $13.7 million , net of tax) related to the derecognition of deferred profit related to sale-leaseback transactions. Our accounting treatment under ASC 842 for leases in which we are the lessor remained substantially unchanged from our accounting treatment under ASC 840. The adoption of ASC 842 did not have a significant impact on our consolidated results of operations or cash flows. ASU 2018-16 — In October 2018, the FASB issued ASU No. 2018-16, "Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes," which permits the use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815. ASU 2018-16 is effective for public companies during interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. We adopted ASU 2018-16 effective January 1, 2019 on a prospective basis for qualifying new or redesignated hedges. The adoption did not have a significant impact on our Consolidated Financial Statements and did not impact pre-existing hedges. Effective in 2020 ASU 2016-13 — In June 2016, the FASB issued ASU No. 2016-13, "Measurement of Credit Losses on Financial Instruments," which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses rather than incurred losses to estimate credit losses on certain types of financial instruments, including trade receivables. This approach may result in the earlier recognition of allowances for losses. In November 2018, the FASB issued ASU No. 2018-19, "Codification Improvements to Topic 326, Financial Instruments—Credit Losses," which excludes operating lease receivables from the scope of ASU 2016-13. ASU 2016-13 is effective for public companies during interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. We are adopting ASU 2016-13 effective January 1, 2020, and we do not currently expect a material opening retained earnings adjustment as a result of the adoption. Further, we do not expect the ongoing application of ASU 2016-13 to materially impact our Consolidated Financial Statements. ASU 2018-15 — In August 2018, the FASB issued ASU No. 2018-15, "Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract," which aligns the accounting for costs incurred to implement a cloud computing arrangement that is a service arrangement with the guidance on capitalizing costs associated with developing or obtaining internal-use software. ASU 2018-15 is effective for public companies during interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. We adopted ASU 2018-15 effective January 1, 2020 on a prospective basis. The adoption is not expected to have a significant impact on our Consolidated Financial Statements.
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.

Sale Leaseback Transaction [Line Items]
Sale Leaseback Transactions [Text Block]	Off Balance Sheet Arrangements. In prior years, the Leasing Group completed a series of financing transactions whereby railcars were sold to one or more separate independent owner trusts (“Trusts”). Each of the Trusts financed the purchase of the railcars with a combination of debt and equity. In each transaction, the equity participant in each of the respective Trusts was considered to be the primary beneficiary of the Trust; and therefore, the accounts of the Trusts, including the debt related to each of the Trusts, were not included as part of the Consolidated Financial Statements. The Leasing Group, through wholly-owned, qualified subsidiaries, leased railcars from the Trusts under operating leases with terms of twenty-two years , and subleased the railcars to independent third-party customers under shorter term operating lease agreements. The terms of the operating lease agreements between the subsidiaries and the remaining Trusts provided the Leasing Group with the option to purchase, at a predetermined fixed price, certain railcars from the remaining Trusts in 2019. On January 14, 2019, we completed the purchase for a purchase price of $218.4 million . As a result, 6,779 railcars previously under lease are now wholly-owned by our Leasing Group. The future contractual minimum rental revenues associated with these railcars are included in the table above.
