摘要： A deadhead return control system for a locomotive or a control car similar to a locomotive having a deadhead stop and a piston valve with the connection status of the piston valve being controlled by the status of the deadhead stop. A first end of the deadhead stop is connected to a pilot end of the piston valve, a second end of the deadhead stop is connected to the atmosphere, a third end of the deadhead stop is connected to the external main air pipe. When the deadhead stop has a closed status, the first end of the stop is connected to the second end of the stop and when the stop has an open status, the first end of the stop is connected to the third end of the stop to allow for the air from said main air pipe to flow into the piston valve.
