The 6600-volt current is collected from the trolley wire by apneumatically-operated pantagraph trolley on each half of thelocomotive, and is carried through a suitable oil switch andcircuit breaker to an auto-transformer in each cab. Thesetransformers reduce the voltage to 325 for use at the trolleys may be raised or lowered from the cab by a suit-able air valve. The three motors on each half of the locomotive are con-nected permanently in parallel, and are controlled by means ofan induction regulator, which, under the direction of the oper-ator, varies the voltage at the motors from about 140 to PLAN OF LOCOMOTIVE, SHOWING ARRANGEMENT OF APPARATUS To liolli y
