The locomotive is divided into two partswith a separate transformer for each motor. Its electricalequipment weighs 43 metric tons and the mechanical parts38 tons. The two motors and gearing alone weigh 56,760lb., the transformers and preventive coils 21,230 lb., the The control connections of this locomotive and the orderof closing the contactors are shown in two accompanyingdiagrams. In the wiring diagram the motor switches aremarked A, the transformers switches B, the field windingC, the motors M-i and M-2 and the transformers T-i andT-2. The maximum pressure supplied to the motor ter-minals is 420 volts. Originally this
