or handling the Penn-sylvania Railroad trains into the New York station andthrough to the yards on Long Island has been delivered andis in operation on the electrified tracks of the Long IslandRailroad. This locomotive incorporates many novel feat-ures in electric locomotive design, and is the result of sev-eral years of co-operative development between the Penn-sylvania Railroad Company and the Westinghouse Electric& Manufacturing Company. The Pennsylvania Railroadwas represented in this work by a locomotive committeecomposed of the chairman, George Gibbs, chief engineer ofelectric traction; A. W. Gibbs, general superintendent ofmotive power; D. F. Crawford, general superintendent ofmotive power, Pennsylvania Lines West, and A. S. Vogt,mechanical engineer. The new locomotive is distinctively a high-powered ma-chine built for high-speed operation. In wheel arrange-ment, weight distribution, trucks and general character ofthe running gear it is the practical equivalent of two Amer-

Pennsylvania Electric Locomotive—Side View ican type locomotives coupled permanently back to back.The motors are mounted upon the frame and side-connectedthrough jack shafts to driving wheels by a system of cranksand parallel connecting rods, similar to steam practice. Theconnecting rods are all rotating links between rotating ele-ments, and are thus perfectly counterbalanced for allspeeds. The employment of this transmission permits themounting of the motors upon the frame, secures their springsupport, and, in common with the rest of the locomotive,the center of gravity at 79 in. above the rail, or approxi-mately the same height above the rails found desirable inhigh-speed steam locomotives. The same freedom of motion in the wheels and axles thatis characteristic of the present steam locomotive designs isalso secured. In these locomotives the variable pressureof the unbalanced piston of the steam locomotive is replacedby the constant torque and constant rotating effort of thedrivin
