Locomotive Crash Energy Management Vehicle-to-Vehicle Tests 1 & 2: Analyses and Test Results

Crash energy management (CEM) components which can be integrated into the end structure of a locomotive were developed: a push-back coupler and a deformable anti-climber. These components are designed to inhibit override and improve crashworthiness for equipped locomotives in a wide range of collisions. A full-scale dynamic impact test program has been designed to evaluate the CEM system. Two sets of coupling tests validated finite element models. Two CEM locomotive vehicle-to-vehicle collision tests and a train-to-train collision test are planned. This report describes the analyses and test results of both the first and second vehicle-to-vehicle impact tests.
