American engineer and railroad journal . e controlled by meansof an induction regulator, which, under the direction of the;•, varies the voltage at the motors from about 140 toThe induction regulators are driven by small seriesmotors of the same general type as the main motors. Bothregulators are controlled by the multiple unit system from amaster switch at either end. They may be stopped at any de-sired point in their travel, and thus the locomotive may berim at any speed with the same facility and economy as asteam locomotive. Forced ventilation is used with the auto-transformers and induction regulators as well as with themotors, the necessary air being supplied by motor-driven blow-ers. Motor-driven air compressors are also used. The locomotive is designed for slow speed freight service,this type having been chosen because the design of seriesalternating current motors for very slow speed service presentsmany more problems and is much more difficult than the de-sign of equal capacities for the ordinary conditions. This. WESTINGHOUSE SINGLE PHASE Ic>cc>\ VE AND FITTY-CAR TKVIN. The weight of the locomotive complete is 135 tons. It isbuilt in two halves, each having one six-wheel truck withrigid wheel base. These are coupled together, and are intend-Lte normally as a single unit, but each half may beoperated separately if desired. The locomotive is approx-imately ft. long over all, and 9 ft. 8 ins. wide. The totalheight above the rail with trolleys lowered is 17 ft. Theare 60 ins. in diameter, and are mounted on 8-in. axles,with •; ft. 4 ins. between centers. The side frames of thetruck are of cast steel and are spring supported in the usualmanner, the weight on tint two inside axles of each truck be-big equalized. The cabs are built . : with angleiron supports, and the- entire cab as a whole is removablefrom the truck.
