Wheel Failure Investigation Program: Phase 2
Although rare, broken wheel derailments tend to be more catastrophic than other derailment types as a sudden fracture can occur in service at revenue train speeds. It is very difficult to detect the hidden defects which cause such events, prior to failure. In February 2016, the Federal Railroad...
Side Impact Test of a DOT-113 Surrogate Tank Car with Water
The Federal Railroad Administration (FRA) conducted a side impact test of a surrogate DOT-113 tank car at Transportation Technology Center, Inc. (TTCI) to evaluate its performance under dynamic impact conditions and to provide data for the verification and refinement of a computational model....
Test Evaluation of Retrofit Collison Post Design for Legacy Locomotives
Legacy locomotives, such as narrow-nose designs manufactured before 1990, were not required to comply with crashworthiness requirements. Therefore, these locomotives afford less crew protection in case of train collisions. In this project, collision posts that offer additional crash...
