Organization, Consolidation and Presentation of Financial Statements [Abstract]
Contract Exits	3. Contract Exits Rail had been manufacturing engineered-to-order ("ETO") equipment under significant long-term, fixed-price contracts with Network Rail and Deutsche Bahn. In June 2026, the Company informed Network Rail that it had ceased all activities relating to its ETO contract to build stoneblower rail maintenance vehicles, and the associated manufacturing facilities have been closed. Also, in June 2026, the Company ceased all activities relating to its ETO contract to deliver utility track vehicles with Deutsche Bahn. As a result of these actions, the Company recorded a loss of $207.4 million during the quarter ended June 30, 2026, which includes the non-cash impairment charges of $40.5 million related to net contract assets, $21.5 million of inventory and $12.9 million of prepaid balances specific to the projects, as well as an estimated incremental liability of approximately $133 million to address future obligations related to these contracts. Of this loss, $136.5 million was recorded as a reduction to Product revenues - Rail contract exit-related adjustments and $70.9 million to Costs of products sold - Rail contract exit-related adjustments in the Condensed Consolidated Statements of Operations. On August 10, 2026, Network Rail notified the Company of its alleged breach under the contract and its intention to reach resolution of contractual damages as a result. The Company intends to vigorously contest any damages based on multiple available defenses. Additionally, the Company has proposed an alternative solution to assist Network Rail in significantly extending the life of their existing fleet of stoneblower machines. It is possible that the estimate of the loss could change based on ongoing discussions with Network Rail, or if the ultimate outcome to this matter were to be determined through litigation. On August 10, 2026, the Company entered into a definitive agreement with Gleisbaumechanik Brandenburg GmbH ("GBM"), a manufacturing partner on the Deutsche Bahn contract, to sell all assets related to the contract, including inventory and intellectual property, to GBM. Through the proceeds from the CE Holdings Note set aside in the Company's initial balance sheet subsequent to the closing of the Transactions, the Company has sufficient cash available to settle any cash payments required to exit these contracts.
