Motors and Control The motor equipments for the new cars will consisteach of four GE-203-P, ventilated, commutating-polemotors, having a normal one-hour rating of 50 hp. at600 volts. The gear ratio used is to be 62:22, equivalentto The control will be of the standard PC-5 type,cam-operated, by means of which the individual con-tactors are actuated by a camshaft and, therefore,open and close in a definite sequence.

BUFFALO-NIAGARA FALLS HIGH-SPEED LINE-USE ON BRIDGES -INSULATOR FOR relay, which is located in the control box, can be so ad-justed that the control circuits are completed at properintervals to maintain the necessary motor current tosecure uniform acceleration of the car. Maximum speeds are to be obtained by tapping themotor fields in the full multiple connection. The appa-ratus to be used for tapping the fields is entirely distinctfrom the main control and consists of a field-tappingunit, including an air-operated cylinder and a current- limit relay mounted in a metal containing box. Thisunit is shown in two accompanying reproductions fromphotographs. The cylinder is held in the off or full-field position by a substantial coil spring. The admis-sion of air to the operating cylinder is effected by asmall magnet valve energized from the control the admission of air, the spring is compressed andthe cylinder moved to the on or tapped-field the failure of either
