Train collisions involving locomotives can result in serious damage and occupant injury due to the larger size and stiffness of the locomotive. In an effort to improve safety for rail passengers and operators, the Volpe National Transportation Systems Center (Volpe Center) on behalf of the Federal Railroad Administration developed concepts for a more crashworthy locomotive with the intent of mitigating structural crush and preventing override. SGH assisted TIAX, LLC and the Volpe Center with designing a crash energy management (CEM) system for a locomotive along with material and component testing.
