Abstract
A train including a brake pipe () and an electrical train line () extending from at least one locomotive through at least first and second cars which are adjacent to each other, the first and second cars each include a brake cylinder, reservoir and a brake valve The first car includes an electro-pneumatic brake valve which is responsive to electric signals on the train line to produce a first car pneumatic apply brake signal from the first reservoir and release brake signal for the first brake cylinder and the brake signal pipe () The first car also includes a first valve () to transmit the first brake signals to the brake signal pipe and to isolate the connection to the brake signal pipe for a breakaway at one of the cars The second car includes a pneumatic brake control valve which is responsive to the first car pneumatic brake signals on the brake signal pipe and brake pipe pressure m the brake pipe to produce a second car pneumatic apply and release brake signals for the second brake cylinder corresponding to the first apply and release brake signals The pneumatic brake control valve also produces a second car pneumatic apply brake signal from the second reservoir for an emergency pressure in the brake pipe and no brake signal on the brake signal pipe.
