. Electric railway journal . ELECTRICAL DEPARTMENT OF THE METROPOLITANSTREET RAILWAY, NEW YORK—II The first portion of this article as printed in the May 21issue of the Electric Railway Journal described the steamgenerating improvements at the Ninety-sixth Street power sta-tion, high-tension betterments and substation changes. Thefollowing paragraphs complete the account of the electrical de-partment. THE NINETY-SIXTH STREET POWER STATION SWITCHBOARD RECON-STRUCTION Equally important changes are under way in the switchboardand wiring at the Ninety-sixth Street power station. Thesituation there before this work was begun was not greatly dif-ferent from that which might be expected in a station built 10years or so ago, and not subsequently brought up to date. Allof the switchboard galleries were congested to their utmostcapacity. The control wires for the oil switches, current trans-formers, potential transformers, etc., were crowded into a cablewell so that there was liability of injury to all incase of a single. Metropolitan Electrical Department—High-TensionFeeders at Ninety-Sixth Street Power Station burn-out. There was also considerable crowding of the controlwires where they terminated under the two control boards. Thehigh-tension wiring ran directly from the a.c. buses to the oilswitches. The management at first thought that it might be possible toinstall porcelain insulators on the individual wires, and sepa-rating the wires as far as possible, thus reducing the liabilityof one wire being affected by the breaking down of another.But further investigation showed conclusively that the recon-struction and complete overhauling of all the switchboard appa-ratus and appurtenances were necessary. Plans were drawn upfor this work, in conjunction with one of the large electriccompanies, and the latter was then requested to submit a bidon the plans which had been decided upon. Its proposalamounted to approximately $100, 000. As this price was toohigh, the general man
