The mileage of the suburban lines ismade up of ISO route-miles, or 289 track-miles of running road, and 34 miles ofsidings. The track will be electrified withl,S0O volts direct current, with overheadwires. Power will be supplied in the formof three phase alternating current at 25cycles per second and will be transmittedat 20,000 volts to twelve substations atvarious points on the system, where itwill be converted into the operating directcurrent of volts. The high tensiontransmission is by underground cablesfrom the power house to the importantsubstations in the central area, and by. \ .sul NIi •trie current is supplied by the generatorto the motors thr<jugh special arrangement is provided so that thefields of the generator are varied and thusa varying voltage from zero to maximumis obtained, so that the resultant speedchanges of the motors produces a smoothand rapid acceleration without loss inresistance or gear changes. It is interesting to note that these carswhich were built by General Electric the long trip across the continentunder their own power, averaging 220miles a day; daylight running, with amaximum days running of 31S miles. More Gas-Electric Great Northern Ry. Co., St. Paul,Minn., recently ordered from the GeneralElectric Co., two gas-electric motor will be of the large 70-foot type,as d»6cribcd aboTe, and will be placed inservice on the branch lino of the.
