Experimental studies of creep force characteristics between wheel and rail have been implemented by rolling contact machinery or wheelsets equipped with roller rigs in general. Some of the reasons are that those kinds of machinery are easy to control the rolling speed of discs/roller rigs and slip (creepage) between wheel and rail, which consequently characterizes the creep forces. Experiments with the machinery, however, are only operable in laboratories, instead on the actual rails in the field. Moreover, the curvature of the actual rails and the discs/roller rigs in the longitudinal direction are different, which is conceivable as affecting the running behaviors of the wheels. Therefore, the authors have developed a new experimental device equipped with the actual rail. The device is able to make a longitudinal creepage change and generate a constant lateral creepage between wheel and rail.
