Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The Company has prepared these unaudited condensed consolidated financial statements in accordance with U.S. GAAP for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the SEC. Accordingly, the unaudited Condensed Consolidated Financial Statements do not include all information and disclosure required by U.S. GAAP for annual financial statements. The December 31, 2023 Condensed Consolidated Balance Sheet information contained in this Quarterly Report on Form 10-Q was derived from the 2023 audited consolidated financial statements. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements, including the notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. In the opinion of management, all adjustments (all of which are of a normal recurring nature) that are necessary for a fair statement are reflected in these unaudited Condensed Consolidated Financial Statements.
Liquidity	Going Concern The Company’s cash flow forecasts, existing cash and cash equivalents, borrowings available under the Senior Secured Credit Facilities and the AR Facility indicate sufficient liquidity to fund the Company’s operations for at least the next twelve months. As such, the Company’s unaudited Consolidated Financial Statements have been prepared on the basis that it will continue as a going concern for a period extending beyond twelve months from the date the unaudited Consolidated Financial Statements are issued. This assessment includes the expected ability to meet required financial covenants and the continued ability to draw down on the Senior Secured Credit Facilities (see Note 9, Debt and Credit Agreements).
Reclassifications	Reclassifications During the nine months ended September 30, 2024, the Company determined that the held-for-sale criteria for Rail was no longer met and, as a result, the Company made reclassifications to prior year amounts previously classified as discontinued operations and assets held-for-sale in the Company's Consolidated Statements of Operations and Consolidated Balance Sheets, along with the accompanying notes to the Company's Consolidated Financial Statements. See Note 3, Discontinued Operations and Dispositions for further details.
