Abstract:
An interface system for interfacing a pneumatic train brake control system to a train of electrically controlled pneumatic (ECP) brake equipped cars, the interface system comprising:a locomotive electrical trainline terminal and a train electrical trainline terminal; a locomotive brake pipe port, a locomotive pressure supply port and a train brake pipe port; a relay valve responsive to a pilot signal for selectively connecting the car brake pipe port to the supply port, atmosphere or lap; and a controller monitoring pressure on the locomotive brake pipe port, controlling the pilot signal to the relay valve in response to the pressure on the locomotive brake pipe port, providing ECP commands on an ECP trainline via the train electrical terminal in response to the pressure on the locomotive brake pipe port, and providing electrical power on an ECP trainline via the train electrical trainline terminal from the locomotive electrical trainline terminal.
