Patent number: 7455370Abstract: A remote radio railroad car located within or at the end of the train that charges or exhausts the brake pipe in response to radio commands from the lead unit. The brake pipe control system includes a first controller at a first car at the lead end for controlling the brake pipe at the first car and transmitting, via a radio link, brake pipe control signals to a second controller in a remote car in the train. The second controller controls the brake pipe at the remote car in response to the brake pipe control signals from the first controller. If the second controller is on the last car and the last car does not include an independent end of train device, the second controller transmits brake pipe condition signals to the first controller. If the second controller is on the last car and the last car does include an independent end of train device, the first controller established separate communication links with the second controller and the end of train device.Type: GrantFiled: November 29, 2005Date of Patent: November 25, 2008Assignee: New York Air Brake CorporationInventors: Kevin B.

Patent number: 7240970Abstract: 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.Type: GrantFiled: September 14, 2005Date of Patent: July 10, 2007Assignee: New York Air Brake CorporationInventors: John M.
