. The Street railway journal . FIG. 3—SINGLE REDUCTION MOTOR CASTINGS. ed: Light weight, ample capacity of the armature andfield windings, large bearing surface in the journals, pro-tection from external injury, very high efficiency, greatstarting torque. The controlling apparatus is second only in impor-tance to the motor.

The diverter is made completelyfireproof, and at the same time there is provided the verybest ventilation. One of these diverters is used on each car, its func-tion being to reduce the current while the motors arebeing started, thereby preventing the sudden jerking ofthe car and unnecessary strain on the motors.
