The results of safety assessment against flange climb derailment depend on the frequency component of the measured data in the field test. Therefore we investigate the relation between the data of derailment quatient to which the filter processing are applied with various cutoff frequencies and the values of wheel rise. We also confirm that the vertical displacement of the wheel caused by flange climbing is relative to the running distance when a vehicle runs on sharp curves at low speed.
