Abstract:The Federal Railroad Administration and the Volpe Center continue to evaluate new technologies for increasing the safety of passengers and operators in rail equipment. In recognition of the importance of override prevention in train-to-train collisions in which one of the vehicles is a locomotive, and in light of the success of crash energy management technologies in cab car-led passenger trains, the Volpe Center sought to evaluate the effectiveness of components that could be integrated into the end structure of a locomotive that are specifically designed to mitigate the effects of a collision and, in particular, to prevent override of one of the lead vehicles onto the other. In a research program completed in 2012, detailed designs for two crashworthy components for a passenger locomotive—a push-back coupler and a deformable anti-climber—were developed, evaluated, and tested. Based on a successful full-scale rail impact test demonstration of component performance, the Volpe Center now wishes to retrofit the designs for these two components onto an F40 locomotive and perform a series of full-scale collision tests. The research described in this report develops and evaluates modifications required to retrofit the design for these two components onto the F40 locomotive.
