Science: Engineering: Invention The Westinghouse Electro-Pneumatic System for Con-trolling; Railway and Other Motors It is a well known fact that under certain conditions in electrictrain operation, important advantages arise in the ability to simul-taneously control, from either end of a train, all the motors of theseveral cars of a train. This problem has been undertaken by Geo. the controlling apparatus, the admission of the air to the severalparts being effected electrically by means of magnets attachedto the air valves. The reliability of pneumatically operatedapparatus has been demonstrated by years of service in railwaywork. In fact, the air-transmitting and applying apparatus,and the electro-magnetic devices employed in this system ofcontrol are standard parts manufactured respectively by theWestinghouse Air Brake Company and the Union Switch & Sig-. FIG. I.—CAR EQUIPPED WITH ELECTRO-PNEUMATIC SYSTEM OF CONTROL Westinghouse, who has invented and personally developed, at theworks of the Westinghouse Air Brake Company, at Wilmer-ding, near Pittsburgh, Pa., an electro-pneumatic system of nal Company. In this respect the Westinghouse method will pos-sess in advance the confidence of railway managers who have hadexperience with the use of these appliances.
