The Street railway journal . power and streetrailway purposes will be dis-tributed from a central step-down sub-station, in which thehigh-tension current at 23,-000 volts will be reduced to2300 volts, and where willalso be located motor-gener-ators, for the conversion of the alternating current to a 500-volt direct current for streetrailway use. This station will consist of a fireproof build-ing, equipped with traveling crane. The electrical installa-tion will consist of three 500-kw induction motors, direct-connected to 575-volt direct-current railway generators,and a synchronous motor set

Themotor-generators have been used instead of rotary con-verters, as it is claimed that they will give better regulation on the periodicity adopted, 60 cycles per second. There isalso 600 arc lamp capacity of constant current transformers, ten 400-kw potential regulators for lighting circuits,twelve step-down transformers of total maximum capacityof 5600 kw, and switchboard equipments for operating the.
