ABSTRACT:
An brake application solenoid valve arrangement for use in an electronic freight train brake control system on a railway car. Such braking system having a brake pipe normally charged with fluid at a certain pressure, separate compartment auxiliary and emergency reservoirs charged at certain pressures with fluid from the brake pipe and a fluid pressure activated brake cylinder device. Flow of pressurized fluid from the separate auxiliary and emergency reservoirs can be selectively supplied concurrently to the brake cylinder device via the single brake application valve. Backflow check valves between each reservoir and the brake application valve prevent the transfer of pressurized fluid between the reservoirs. The electronic controller can operate the application valve to control the braking and release functions responsive to electrical command signals. A pneumatic control valve can also be operatively incorporated into the brake control system.
