Abstract:

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 protection were fabricated and installed on a legacy locomotive underframe. Structural tests conducted with the upgraded underframe using appropriate loads showed that the maximum stresses were within acceptable limits. Further, the measured strains correlated well with the expectations from design simulations, thereby validating the robustness of the retrofit design.
