. Electric railway journal . amper. The oil supply to theburners of the furnaces and the steam for atomizing the oilare thus controlled automatically with the load. Space has The main operating switchboard is located on a gallery at theside of the turbine room and 15 ft. above the floor of the latter,to give the operator a clear view of the machinery. For thesame reason a chief engineers office has been located on thegallery. Above this is the high-tension switch room containingthe high-potential oil switches and selectors connected with the33,000-volt busbars. Either turbine can be run on either 2300-volt bus. There are three exciters in the Webster station, twobeing steam-driven and one motor-driven. The main switch-board on the operating gallery contains 10 panels; three arefor exciter service, two for alternators, two for outgoing lines,one for transformer and one each for station lighting andpower and substation feeder service. The transformers arelocated beneath the main switchboard in a bay off the turbine. Galveston-Houston Railway—Floor Plan and Grade Level s of Webster Power Station been provided for two future coal conveyors in case oil issuperseded by coal. In this connection an ash-handling system,with gravity delivery from hoppers into cars on a narrow-gagetrack, can readily be provided. The turbine room is served bya 25-ton Case electrically operated crane of 48 ft. $y2 in. span. ELECTRICAL FEATURES The output of the turbo-alternators passes through 2300-voltoil switches to one of two sets of busbars via selector knifeswitches which permit the units to be operated on the same orseparate buses as desired. Three 500-kw, 2300/33,ooo-volt,water-cooled, oil-insulated transformers are installed in thestation, and connected with each set of 2300-volt busbarsthrough oil and selector switches. The high-tension side ofthe transformers is connected directly to the 33,000-volt busthrough connecting switches. There is a single 33,000-volt bus,with provision for
