1. An air brake control unit, comprising:
a first electronic brake valve connector for receiving a first braking command signal from a first electronic brake valve of a first locomotive;
a first electro-pneumatic control unit for operating a braking system of a train in response to the first braking command signal received from the first electronic brake valve;
a relay for selectively connecting and disconnecting a power source of the first locomotive to the first electro-pneumatic control unit so that the first electro-pneumatic control unit does not receive any power from the first locomotive when the relay has disconnected the power source from the first electro-pneumatic control unit; and
a first inter-unit connector for establishing a power connection between the first electronic brake valve and a second electro-pneumatic control unit of a second air brake control unit of a second locomotive as well as a power connection between a second electronic brake valve of the second locomotive and the first electro-pneumatic control unit so that the first electro-pneumatic control unit can receive power from the second locomotive.
