A tread surface cleaning system has a cleaning element mounted to a truck frame of a steering truck in a position facing a tread surface of a wheel. The cleaning element moves freely to come into contact with and to move away from the tread surface. A pressing-load application spring biases the cleaning element toward the tread surface and a stopper restrains the cleaning element from approaching the tread surface. A forward and backward movement of a wheel axle 2 in the travel direction caused by steering is used so that the cleaning element makes contact only on the inner rail side toward which the tread surface of the wheel approaches when passing through a curved section. The cleaning element does not make contact on the outer rail side from which the tread surface moves away when passing through a curved section and when traveling through a straight section.
