To reduce secondary damage after the train is derailed by the earthquake vibration, it is important to know the behavior of the train set running at the high speed. When the derailed wheelsets run on a ballasted track, derailing wheels run on the sleepers and running resistance occurs to the vehicle because the wheels hit and bounce to the sleepers. To understand the running resistance and estimate the train set dynamic characteristics, we performed the experiment where 1/10 scaled vehicle model ran on steel sleepers at high speeds. We show the following results. (1) Equivalent running resistance coefficient was calculated from entrance and exit running speed of the test area. From the comparison between running on the flat plate and running on the sleepers, resistant coefficient on the sleepers was remarkably larger at 10〜70km/h speed than that on the flat plates. (2) There seems to be a relation between the size of the equivalent running resistance coefficient and the number of sleeper traces.
