The Uceta GP16 was a series of rebuilt diesel-electric locomotives, a result of a remanufacturing program initiated by the Seaboard Coast Line Railroad in an effort to spare the cost of purchasing new motive power in the late 1970s. This involved the rebuilding of their aging fleet of 155 EMD GP7, GP9, and GP18 road switchers (many of which were over twenty years old). ==The program== The required modifications took nine weeks per unit on average to complete. The program resulted in a cost savings of almost 50% over buying new locomotives. Included in the program: * Rebuilding the underframe assembly; * Remanufacturing the Blomberg B two-axle trucks, generators, and traction motors (all GP16s were configured with a B-B wheel arrangement); * Replacing the existing 567 prime mover with a new EMD 645 series diesel engine, which boosted the horsepower rating to 1,600 in the case of the former GP7 locomotives. This gave rise to the ''16'' designation. * Removal of the dynamic brakes, and installation of a new type 26L air brake system. * Installation of a new high-voltage cabinet. * Lowering the front nose of the carbody to improve visibility, and retrofitting with a new cab and standard AAR control stand. Ancillary benefits included a lowered engine idling speed and increased fuel efficiency. SCL committed over 100 of its personnel to the conversion program. The first GP16 emerged from SCL's Uceta (Tampa) shop in June 1979 while the last was placed into service during November 1982. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「GP16」の詳細全文を読む スポンサード リンク
