ABSTRACT:
A brake pipe charging cut-off arrangement for a locomotive air brake in which a rate sensing valve responds to an emergency rate of reduction of brake pipe pressure to vent the control chamber of an actuating valve. This causes the actuating valve to be positioned to connect pressure to the brake pipe cut-off valve of the locomotive brake valve device to interrupt charging of the brake pipe. Following a predetermined time delay of such duration as to assure a complete halt of the train by the resulting emergency brake application, the rate sensing valve automatically resets to terminate venting of the actuating valve control chamber. The actuating valve is then conditioned to be reset on the lead unit by movement of the brake valve handle to emergency position. On a trail unit, a unique arrangement of double check valves sense the proper operating condition of a trail unit brake valve device to automatically reset the actuating valve.
