On the wheel climb derailment, the wheel flange touches on the side of the railhead where is located a little far from the center of the wheel, and the wheel rounds around the touch point as the center and claims up from the rail. Therefore, to investigate the behavior of the wheel under the derailment condition, it is necessary to appreciate the contact point position. However, it has been said to be impossible to measure the position. The authors proposed a new method to easily and precisely measure the touch point. Using a model track and a model truck, several experiments were done to measure the positions under various rail attack angles and on various covertures. As the results of the experiments, the points are variously changed according to the attack angles and the radius of the overture. This paper is described the results of the investigation.
