SYSTEM FOR DISCONNECTING ANY DESIRED CAR IN A TRAIN

摘要

A system for disconnecting any desired car from a train of cars in which an actuating air supply line and an instruction air line are connected to a compressed air source in a locomotive to extend through the train. Air under low pressure is continuously supplied to the actuating air supply line extending through the cars, and the operator manipulates an on-off control valve in the locomotive by the number of times corresponding to the car number of the desired car to be disconnected. In response to the on-off manipulation, the instruction air conduits in the cars are successively charged with instruction air supplied from the instruction air line and are then exhausted until finally the instruction air conduit in the desired car is charged with air. Then, air under high pressure is supplied through the actuating air supply line to air conduits in the specific car to actuate a coupler unlocking means thereby releasing the coupler.
