It is fireproof and has steel rooftrusses and asbestos-covered corrugated iron roofing. December 2, 1916J ELECTRIC RAILWAY JOURNAL 1143. UTAH SUBSTATION BRINGHURST SUBSTATION OF SALT LAKE & UTAH RAILROAD, SHOWING INCOMING HIGH-TENSION LINES; ALSO THREE-PHASE AIR-BREAK SWITCHES AT POINT WHERE TAP LINE TO SUBSTATION CONNECTS WITH TRANSMISSION LINE The energy is received from the Utah Power & LightCompanys lines at 44,000 volts and delivered to thetrolley line at 1500 volts through two 750-volt, 250-kw. rotaries connected in series. At present there arethree rotaries installed with wiring so arranged thatany two can be operated together. The station andswitchboard will care for two additional rotary con-verters and the accompanying transformers, which willgive the station an ultimate rated capacity of 1000 kw. Conduits have been laid to care for the equalizingcables which will be necessary when the two sets ofrotaries are operated in parallel. In the future instal-lation, a three-pole breaker will be mounted on the nega-tive panel to care for the three equalizer leads, andthis breaker will be
