Many trains were derailed and damaged by the earthquake in Kobe on January 17, 1995. At the same time, many railway girder bridges and viaducts were seriously damaged by the quake. It was postulated that serious accidents could occur as a result of trains running at high speeds into these girder bridges or viaducts. Fortunately, no fatal accidents occurred. On investigating such accidents, the authors found that they rarely occur, because a train derailed by the violent shock of a quake is so radically decelerated by the huge running resistance caused by the derailment that it stops just after the quake. On the other hand, it takes some time until the bridges or viaducts collapse after the quake.
