ABSTRACT:
A remote handle operating mechanism for a cut-out cock located on the back side of a pipe bracket on which the service and emergency portions of a railroad brake control valve device are mounted at the front side thereof. A push-pull rod extends from the cut-out cock actuating lever via an opening in a detent bracket to the front of the pipe bracket to facilitate operation of the cut-out cock. A locking rod affixed to the push-pull rod co-acts with the detent bracket to latch the push-pull rod in either one of two positions corresponding to the open and closed positions of the cut-out cock to prevent inadvertent operation of the cut-out cock.
