This project examined the structural susceptibility of tank car fittings during derailments. The report identified non-pressure cars as being the most susceptible to derailment damage. A DOT111A100W1 fuel service car was selected for analysis. Two derailment scenarios were modeled. The first simulated a severe derailment, were the tank car body is thrown off its trucks with significant momentum. The second simulated a nominal rollover, which is more representative of a low speed yard derailment. Simulation results indicated failure of multiple components in the fittings structure for both scenarios, implying that conventional non-pressure car top fittings are likely to suffer damage and cause lading release under most derailment scenarios.
