A system for exhausting hazardous stored energy from a pneumatic subsystem of a railcar, comprises: an air supply for delivering air to the pneumatic subsystem of the railcar; and an isolation valve interposed between the air supply and the pneumatic subsystem of the railcar. When the isolation valve is in a normal operating position, a supply port and a delivery port of the isolation valve are in fluid communication with one another, but when the sliding shoe is in the second position, the sliding shoe effectively closes access to the supply port, and the delivery port is in fluid communication with an exhaust port of the isolation valve. The isolation valve further includes a means for locking the sliding shoe in the second position.
