This report shows the results of contact experiment between wheelset model and actual rails, to investigate the effect of dynamic displacement. Here, the dynamic displacement is the value which replaces the static displacement of rail inclination, settlement and sluck. We have obtained the following three conclusions by the contact experiment. First, as the attack angle of the wheelset becomes large under any conditions to give a dynamic displacement, the contact point moves in front of the wheel and also the distance from the flange vertex becomes short and the contact angle tends to decrease. Second, there is no contact in the combination of all wheels to the designed rails. Finally, there is no contact in the combination of the worn rails and the designed wheel, but the flange tip part contacts in a small dynamic displacement in the combination of the worn rails and the worn wheel.
