  • Trail locomotive brake control
    Patent number: 7240970
    Abstract: A brake controller for a locomotive includes a train brake pipe, a locomotive brake pipe, a brake cylinder, a control valve and a relay valve. The first control input of the relay valve is selectively connected to one of the output of the control valve and the locomotive brake pipe; and the second control input of the relay valve is selectively connected to the locomotive brake pipe when the control valve output is a release signal. A first electro-pneumatic valve, when activated, causes the control valve to be a release signal. An electronic controller is connected to a first pressure transducer for the locomotive brake pipe, a lead/trail mode switch and the first electro-pneumatic valve; and activates the electro-pneumatic valve for brake release pressures in the locomotive brake pipe when the mode switch is in the trail mode.
