摘要:
A method of setting an electropneumatic brake device (45) on a rail car to a mode of operation includes applying a wake-up voltage on a tramline (40) to each brake device connected to the tramline (40). A command signal is sent to each brake device (45) to enter a requested mode of operation. An acknowledgement signal is received from each of the brake devices (45) on the trainline (40), and a command signal is sent to each brake device (45) to stop broadcasting.
摘要:
An integration train brake system including a single brake controller providing locomotive and train brake commands. A first control (41, 42, 44, 45) transmits a car brake signal on an electrical network (40) for train brake commands to EP cars. A second control (20, 26, 27) transmits a locomotive brake signal on the locomotive brake pipe (21) for train and locomotive brake commands. The brake system may have a pneumatic mode and electrical mode. The first control (41, 42, 44, 45) transmits car brake signals on the network (40) in the electrical mode and the second control (20, 26, 27) transmits car brake signals on the train brake pipe (21) for the pneumatic mode. The second control (20, 26, 27) transmits locomotive brake signals on the locomotive brake pipe (21) in either mode. If the train is all electropneumatic, cars and locomotive braking signals are provided on the network (40).

摘要:
An interface system (10) includes locomotive and car electrical trainline terminals (18, 19), locomotive and car brake pipe ports (12, 14) and a locomotive pressure supply port (16). A train brake pipe valve (28) controls pressure on the train brake pipe port (14). A controller (60) monitors pressure on the locomotive brake pipe port (12) and controls the train brake pipe valve (28) in response to pressure on the locomotive brake pipe port (12). The controller (60) also provides ECP commands on the train electrical terminal (19) in response to pressure on the locomotive brake pipe port (12) and provides electrical power on the train terminal from the locomotive electrical trainline terminal (18). The car electrical terminal (19) is connected to the ECP trainline (110) for providing ECP commands and power to the ECP equipped train devices. The controller may also control an emergency valve (50) to produce an emergency signal on the locomotive brake pipe port (12). A transition valve (58) on the brake pipe port allows bi-directional connection of the interface system.
