This paper presents the development of "On board friction control system" which improves curving performance of railway vehicle by controlling the creep force between wheel and rail. This system consists of control unit, friction modifier tank, spraying nozzle and transponder. Water based friction modifier is sprayed from the trailing bogie truck of the last car on top of the inner rail at curve section detected by the transponder. Experimental results on the service line show decrease of lateral force at the outer rail, reduction of lateral vibration at the inner rail and squeal noise. Long-term observation at the service line proves the effect of friction control that coefficient of friction between wheel/rail keeps lower than the ordinary condition.
