In the 1995 Hyogo-ken Nanbu Earthquake, many railway facilities sustained severe damage. Totally thirty-two railway bridges collapsed, eight of which occurred along the San'yo express line. Accidents such that trains fell into a collapsed part of bridge, fortunately, did not occur. A high-speed train and a mass transportation system recently are promoted, therefore the preparedness for a serious accident is inevitable. We here assumed an earthquake-induced train accident Trains and inside passengers were modeled as 3D distinct elements and their behavior was simulated by DEM. Impact forces on human bodies were computed and damage level were discussed by Chest-G and HIC in the automobile engineering.
