To quantitatively evaluate the possibility of wheel climb derailment, it is necessary to appreciate the friction coefficient μ on the site of the contact point position between the rail and the wheel under the critical derailment condition. However, it has been considered to be impossible to gain such values. Under the critical derailment condition, the relation ship between the derailment coefficient Q/P and the μ is shown by the Nadal's Equation. Therefore, the μ may be able to gain from the Q/P on the critical derailment condition. The authors proposed a new method to exactly detect the moment when the wheel is put under the wheel climb critical condition. Using a model track and a model truck, several experiments were done to gain the μ under various rail tread conditions. This paper is described the results of the investigation.
