All ofour high-voltage transmis-sion lines carry alternatingcurrent, and it is necessaryonly to reduce the voltageto make it suitable to oper-ate electric lights, toasters,and washing motors which drivethe Key Route interurbantrains, however, are notdesigned to operate on alternating current,so it is necessary to change the power fromalternating to direct current before it canbe used by them. This is done at StationE, Piedmont, by means of two motor-generator sets, each of which is essentiallya large alternating current, synchronousmotor, which is coupled to and drives alarge generator which produces direct cur-rent. Thus, the current goes in as alternat-ing and comes out as direct current of avoltage suitable to drive the motors on the.
