^ is practicallylevel. Between Exeter and Lemon Cove the land is transmit eight miles in each direction to the sub-stations on the Lemon Cove and Visalia divisions.Transformers in these stations reduce the 15 cycle, 11,-000 volt, single phase supply to the trolley pressure,3300 volts. The frequency changer sub-station contains six150 k. w. oil insulated, water cooled, 35,000 to 2200volts, 60 cycle Westinghouse transformers, and twotwo-bearing motor generator sets, each composed of a540 h. p. Westinghouse synchronous motor wound for2200 volts, 60 cycles, with induction motor for starting;

Westinghouse Fifteen-Cycle Single-Phase Electric Locomotive on Visalia Electric Railwaj. of a rolling nature, but the maximum gradient on theroad has been kept down to 0.9 per cent, and the curvesare of long radius. The worst conditions are met ona combined ten degree curve on a 0.9 per cent grade. For this electrification, three-phase, 60 cycle poweris purchased at 35.000 volts, from the Mt. WhitneyPower Company, which operates a hydroelectric gener-ating plant on the Kaweah River. At the Exeter sub-station, nearly at the center of the present railway line,the 60 cycle power is stepped down to 2200 volts, andthen converted to 15 cycle, 11,000 volt, single-phasecurrent by a Westinghouse sjnchronous motor gen-erator set. From the main frequency changing sub-station at Exeter, the 15 cycle, 11,000 volt feeder lines,inade up of a pair of No. 4 bare copper conductors. direct connected to a 375 k. w. rotating field, singlephase Westinghouse alternator, delivering 11,000 volts,60 cycle curr
