184. Q. What will be the effect if the release pipe breaks?
A. The holding feature of the brake will be lost; that is, the brake will release when the automatic brake valve is returned to release or holding position.
185. Q. If the brake cylinder pipe breaks, can the locomotive brake be applied with the automatic brake valve? With the independent brake valve?
A. This depends on where the pipe breaks; if between the cut-out cock and any one of the brake cylinders, close the cut-out cock to that cylinder, and the other cylinders may be used. But if the pipe breaks between the control valve and the double-throw check valve, the automatic brake is lost; if the break be between the independent brake valve and double-throw check valve, the independent brake is lost.
186. Q. If the brake cylinder pipe breaks and is not plugged, what must be done?
A. Close the cut-out cock in the main reservoir supply pipe, this to avoid the waste of air when a brake application is made on the train.
187. Q. If the brake pipe connection to the control valve breaks, what should be done?
A. Plug the end leading from the brake pipe; the automatic brake cannot be applied on the locomotive, but the independent brake will not be affected.
188. Q. If the control cylinder pipe breaks, what effect will it have and what must be done?
A. The locomotive brake cannot be applied with the automatic brake valve; by plugging the pipe, this feature of the brake will be restored, but the independent release feature will be lost.
