Crash Performance for Lightweight, High Speed Trains

Washington, DC




The high speed train industry relies on relatively lightweight equipment to conserve energy and to minimize the effects on infrastructure and rolling stock design.  Recent crashworthiness recommendations presented by the Federal Railroad Administration (FRA) Engineering Task Force (ETF) to improve collision safety could lead to increased train weight and the high speed train industry requested further evaluation.  Working for the FRA, SGH evaluated existing technology and the resulting impact on the weight of the train.
