Contingencies [Abstract]
Contingencies	Note 18. Contingencies In June 2011, the Company received a letter from the Federal Railroad Administration (“FRA”) containing a railworthiness directive pertaining to a specific design of tank cars manufactured by the Company for use in transporting poison inhalation hazard materials. The Company has manufactured 948 railcars of this design. These tank cars are owned and managed by the Company’s wholly-owned, railcar leasing subsidiary. The FRA was notified of five tank cars with potential leaks around the manway nozzles. Pursuant to the directive, 100 recently manufactured tank cars were removed from service. An additional 62 randomly selected tank cars out of 848 manufactured since 2006, which have operated without incident, are being removed from service. These railcars will be tested in accordance with FRA-approved and witnessed testing procedures currently under development. At this time the outcome of this matter cannot be predicted and the amount of any potential costs and expenses incurred for compliance with the directive cannot be reasonably estimated. The Company is involved in claims and lawsuits incidental to our business. Based on information currently available, it is management’s opinion that the ultimate outcome of all current litigation and other claims, including settlements, in the aggregate will not have a material adverse effect on the Company’s overall financial condition for purposes of financial reporting. However, resolution of certain claims or lawsuits by settlement or otherwise could impact the operating results of the reporting period in which such resolution occurs. Trinity is subject to Federal, state, local, and foreign laws and regulations relating to the environment and the workplace. The Company has reserved $8.0 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.
