The authors proposed a new method which could easily and precisely detect the contact point position between the rail and the wheel under the critical condition of wheel climb derailment. As the result of the experiment using the above mentioned method, they found that the position was variously changed according to rail attack-angles and wheel lift-up values from the rail tread. The next, employing the contact point position, a new conception was proposed to theoretically calculate the wheel lift-up value from the rail tread when a wheel climb derailment occurred. Using a model track and a model truck, experimentation was done to examine the difference between the theoretically calculated value and the practically measured one on the wheel lift-up value. The result obtained was very much in agreement with the theoretically calculated value and the practical lift-up one.
