The street railway review . occupies one side of the building the cor-responding space in the other portion being in three stories, therotary converters and switchboards being on the lower floor andthe boiler room with six joo-h. p. Cahall water-tube boilers abovewith ash room between. The boilers are equipped with Roncystokers. Above the boilers are coal bunkers of 400 tons capacity.sered by a mechanical conveyor; the ashes are also handled bya conveyor. In the up-takes to the stack arc two 14-ft. fans asthe induced draft equipment. City water is used in the boilers, and for condensing purposeswater is taken from the Sound. Two 24-in. pipe lines 500 ft. longprovide for suction and discharge for the condensers which areof the Wheeler admiralty type. The circulation is effected by twoNo. 12 Wheeler centrifugal pumps. 550-volt three-phase rotaries for the railway road. There is also adifferential field booster for regulating the voltage of a 500-kw. h.railway JKittery Installed by the Electric Storage Battery Co.. WmiXO IN BASEMENT—SEATTI.R EI.ECTRTC CO. Jan. 20. igc+l STREET RAILWAY K1-TEV. All the rotary CL>nverlcrs are Westinghousc ma-chines and are eiiuipped with Westinghousc TypeC starting motors. The railway hallery mentioneH is located abovethe engine room. Beside? this there is a i.ooo-kw.h. battery with voltige from 230 to 306, located inthe basement, which was pnt in last fall. This isalso Electric Storage Battery Gos, installation, andcomprises i, coo-kw. plates in 1.500-kw. cells to giveopportunity for increased capacity. There are two switchboards, that lor the genera-tors and rotaries being at the floor level, and thefeeder board in a gallery. Both boards haveglass gangways behind them for the use of attend-ants. The station was designed to generate 3, 200 kw.and to transform some 2, 400 kw. of power(3.250 h. p.) from the Snoqualmie Falls plants, which is transmitted at 30.000 volts three-phaseto this sub-station where it is transformedto 2, 3CO vol
