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.

A manifold protective valve enclosure can have a bottom portion and a valve mounting subbase portion disposed on the bottom portion. A portion of the perimeter of the bottom portion can be surrounded by side walls which surround a valve which can be mounted on the subbase portion. A cover can be provided over the side walls to completely enclose and protect both the subbase and the valve. A portion of at least one side wall can form a side of the subbase, or integral conduit members can provide fluid communication between the side of the subbase and the side wall. The subbase can have the requisite ports configured to mate with the ports in the valve and can also have an override port configured to connect to an external device. The subbase can further include a receptacle for an electrical connector on the valve. The subbase can also include accessory devices such as mufflers, shut-off valves and flow controls. Passageways through the side walls can provide fluid communication between external connections and the subbase. Additionally, access holes through the side walls can provide access between an external electrical source and the receptacle on the valve subbase. The bottom portion can also have integral mounting portions configured to attach the manifold protective valve enclosure to a wall or other support surface.
