The large lateral force, which acts on the wheel when railway vehicle passes a sharp curve, is one of the factors causing wheel flange climbing. In order to reduce the wheel lateral force, it is considered that lubrication of inner rail is effective. However, it seems that there is few report about the effect of the lubrication of inner rail on the wheel flange climbing. In this study, the behavior of the wheel flange climbing is investigated using a 1/5 scaled truck with a single wheelset on a roller rig. The inner rail-wheel is lubricated with water. As a result, under the condition with relatively large lateral external force on the wheelset, the wet rail condition tends to cause wheel flange climbing more easily than the dry rail condition if its attack angle is small.
