After an occurrence of this kind and atthe first opportunity a full service reduc-tion of brake pipe pressure should bemade and the brake valve cut-out-cockclosed, a movement to release position plugged and the brake valve used as athree-way cock to the end of the trip. If the blow started while going alongthe road with the valve handle in runningposition and tlie brake could not be keptfrom applying by a movement to releaseposition it would mean a broken equaliz-ing reservoir or gauge pipe and both thebroken pi
