Abstract:
The present locomotive brake control system includes a vacuum relay valve responsive to air brake apply and release signals on the air brake pipe to provide vacuum brake apply and release signals on a vacuum brake pipe. A locomotive brake controller is responsive to the brake apply and release signals on the air brake pipe to control the brake cylinder to apply and release the locomotive brakes in an air mode, and is responsive to the brake apply and release signals on the vacuum brake pipe sensed by a transducer to control the brake cylinder to apply and release the locomotive brakes in a vacuum mode.
