At these sub-stations the arrange-ment of the high-tension switches permitted the line being cutthrough from the Tacoma station to the Seattle station. At Georgetown sub-station. There is also a 300,000-c. m. feeder extend-ing from the Georgetown sub-station to the Milton sub I passenger service between Tacoma and Seattle includes 34. PASSENGER AND FREIGHT STATION AT KENT. present current is received at the Tacoma receiving station of theTacoma Railway & Power Co. at 50,000 volts and delivered to thethree sub-stations at 27,000 volts. Two 500-kw., 2,300 to 27,000-volttransformers at Seattle furnish a relay in case of failure of thetransformers in Tacoma. When the 27,000-volt line is changed tocarry 55,000 volts pressure, there will be two independent transmis-sion lines from the power house at Electron to Bluffs, and fromBluffs to Tacoma and Seattle. Sub-Stations. As previously stated there are three sub-stations located respectivelyat Milton, Kent and Georgetown. Each sub-station consists of a brickgenerator and transformer building 25x40 ft. in size, and a woodenbattery room 5ix5_>T j ft. in size. A brick fireproof wall separatesthe transformer and generator rooms. The original equipment ofeach consists of two 180-kw., oil-cooled transformers which step downthe three-phase current
