The Street railway journal . rosperous for several years, and it isprobable that any of the proposed lines would be a financial suc-cess, especially when the city is experiencing a steady and reason-ably rapid growth. Single-Phase Equipment for Washington, Baltimore &Annapolis Interurban Railway As announced in the last issue of this paper, the WestinghouseElectric & Manufacturing Company, of Pittsburgh, has con-tracted for the equipment, with alternating-current apparatusthroughout, of the Washington, Baltimore & Annapolis ElectricRailway, which is to operate an interurban system, including aline from Washington to Baltimore about 40 miles in length, anda branch to Annapolis 15 miles in length. Single-phase, alternating current will be generated in a mainpower house located at Hyattsville, by three 1500-kw single-phase Westinghouse generators, delivering current at 15,000 voltsand driven by Hamilton-Corliss cross-compound engines. Thisstation is of more than average size, and is, in no sense, experi-. MAP OF WASHINGTON, BALTIMORE & ANNAPOLIS INTERURBAN RAILWAY mental. The power house will be built of brick with stone andconcrete foundations, and will contain, in addition, two 125-vcitdirect-current generators to be used as exciters for the alternators,and a large switchboard with electrically-operated oil switches,circuit-breakers, lightning arresters, etc. Current will be dis-tributed from the power house at 15,000 volts to transformer sta-tions located at suitable intervals along the line. These trans-former stations wdl contain only stationary transformers with thenecessary switches and fuses, but no moving machinery, and willnot, therefore, require the presence of an attendant. From thesestations, current will be fed to the single trolley wire at 1000 pressure of 1000 volts, which has been adopted for the trolleywire, is not a necessary part of the system, as a much highervoltage could have been used if it had been deemed advisable bythe engineers o
