ABSTRACT:
An electronic pneumatic brake system for trains which significantly improves brake cylinder pressure build-up time and facilitates essentially instantaneous and simultaneous braking on all cars of the train. The electronic pneumatic brake system includes electronic pneumatic control valves on the cars which individually control the braking on each car or a pack of cars and which are regulated by an electronic pneumatic controller on each car that receives electronic braking and release signals by way of wireless communication from an electronic head end unit on the lead locomotive, or where no head end unit is provided in the locomotive, receives pneumatic braking signals through the brake pipe.
