ABSTRACT:
A pneumatic/electro-pneumatic brake control system including an interface unit at each control station at the opposite ends of a train operating in push/pull service. This interface unit includes a plurality of pressure switches for sensing the operating condition of the brake valve at the respective control station in order to effect an electro-pneumatic brake application on the train via an application relay in bypass of the master controller, when the brake valve is cut out, thereby permitting the operator to leave the train with the brakes safely applied while changing control stations. The arrangement is such as to permit this brake application to be released at the time the operator boards the train at the opposite control station by cutting in the brake valve thereat and moving the brake valve handle to release position to energize the release train-line wire via the master controller at the new control station.
