October, ig LOCOMOTIVE ENGINEERING. 475 Coupling for Train Pipe and SignalPipe. Editors: On passenger trains of the present dayif the train pipe were to become disabledfrom any cause, so that the air brakecould not be used on that particular car;naturally the first thing thought of wouldbe to switch that car behind, so that theair brake could be used to get to theterminal station. The writer has often thought, howmany engineers and trainmen wouldthink of any other plan to get in, usingthe brake, and not switching the car be-hind. The majority of railroads in the UnitedStates are now using the train signal ap-paratus. Now if each passenger crew, orpassenger locomotive, were supplied witha p
