Many damages to railway facilities are reported in the past earthquakes. Especially in the 1995 Hyogo-ken Nanbu Earthquake, totally thirty-two railway bridges were collapsed. Fortunately the train accident caused by the damaged bridge has not been reported so far. Although the large earthquake that strongly affects the train behavior hardly occurs, the effect of the accident to the human society is unpredictable once such large earthquake has occurred. In this study, we modeled trains and inside passengers as the distinct elements and simulated their behaviors by DEM. The impact force to the modeled human body is computed and compared with the results of the experiments subject to the car accident for the calibration of the parameters. It is found that the velocity of 50-60km/h is a transition speed for both behaviors of the trains and the passengers.
