Of the twelve cars six are being equippedwith the 240-C motor and PC-2 control of the GeneralElectric Company and six with the 302-F-2 motor and214-A control of the Westinghouse Electric & Manufac-turing Company. The GE 240-C motor is a recent design of thebox type with nose for motor support cast integralwith the frame. Its weight complete, with gear, gearcase, pinion and axle linings is 4000 lb. A high con-tinuous capacity is obtained by the use of the GeneralElectric Companys system of double or multiple ventil-ation. A fan that has two sets of blades and that hasa greater diameter than the armature, is made integralwith the pinion-end armature head. Hooded openingsare provided in the commutator end-frame head for. BELMONT TUNNEL EQUIPMENT—MOTOR ASSEMBLEDCOMPLETE the entrance of cooling air. As the air enters itdivides into two parallel streams, one passing aroundthe field coils to the fan, the other being drawn throughthe commutator shell and the armature core. Thestreams unite after passing through the fan and areexhausted to the atmosphere through openings providedin the frame. Air at atmospheric temperature is thusintroduced almost directly into the armature core, ef-fectively cooling it and largely increasing the servicecapacity of the motor. The control furnished with the motors is theSprague, G. E. Type-PC-2 multiple-unit electro-pneu-matic type, the apparatus consisting in general of twoparts, a main or motor controller located below the car,and a master controller which regulates the operationof the motor controller. The motor controller is a series-paralleling group often switches or contactor units, a reverser, two linebreakers, overload, potential, and curr
