Real size carbodies of railway vehicles were tested under static compression load in order to evaluate crush behavior at train collision accidents. A light weight stainless steel carbody structure was the target of this study. The FE analysis was carried out to validate the compression tests. These results provided the compression load versus deformation characteristics of the end structures of rail-car bodies. The multi-body system (MBS) model was also used to simulate the train crash behavior. The load versus deformation curve by the compression tests and FE analysis was introduced to the non-linear spring characteristics. The result by the MBS simulation shows the typical behavior of rakes at accidents, i.e. overriding phenomena of the vehicles involved in the collision.
