Claim:
1. A system comprising: an air source for supplying compressed air on board a vehicle having a wheel that travels on a route; a nozzle fluidly coupled to the air source and configured to direct a flow of compressed air from the air source to a contact surface of the route; a valve positioned intermediate the air source and the nozzle, the valve being controllable between a first state in which the compressed air flows from the air source to the nozzle, and a second, disabled state in which the compressed air is prevented from flowing to the nozzle; a controller for controlling the valve between the first state and the second, disabled state; and an operator interface electrically coupled to the controller, the operator interface including a momentary disable switch biased to a position that controls the valve to the first state and movable against the bias to control the valve to the second, disabled state; wherein the operator interface includes a monostable button actuatable to selectively toggle the valve between the first state and the second, disabled state, and wherein the controller is configured to automatically control the valve to the first state after a predetermined period of time has elapsed and to automatically control the valve to the first state after a certain distance has been traversed.
