The British Rail Class 92 is a dual-voltage electric locomotive which can run on 25 kV AC from overhead wires or 750 V DC from a third rail. It was designed specifically to operate services through the Channel Tunnel between Britain and France. Eurotunnel indicates the Class 92 locomotive as the reference for other locomotives which railway undertakings might want to get certified for usage in the Channel tunnel. Locomotives of this type are operated by GB Railfreight/Europorte 2 and DB Schenker. In France, a number were also owned and operated by SNCF; these were classified as CC 92000 on French railways. The class 92 was intended as a mixed traffic locomotive for hauling both international freight trains and the ill-fated and never introduced ''Nightstar'' passenger sleeper trains though the Channel Tunnel. Since introduction the fleet was exclusively allocated to freight, however, in March 2015 six locomotives owned by GB Railfreight have begun passenger operations hauling the Caledonian Sleeper on behalf of Serco between London and Scotland, marking the very first use of the class in commercial passenger service. ==Design== The fleet of 46 locomotives was built by a consortium of Brush Traction and ABB Traction. Parts construction was sub-contracted, with final construction and commissioning being undertaken at Brush's erecting shops at Loughborough between 1993 and 1996 (First unit was produced from 1992, and was finished in April 1993). The bodyshells, shared with the Class 60 diesel locomotives but with a modified front end, were fabricated by Procor (UK) of Horbury and delivered pre-painted in the then-standard triple grey livery.〔(rolling stock : class 60 )〕 Propulsion is provided by two ABB traction converters using GTO devices, with control via an ABB MICAS-S2. Maximum power is on 25 kV or on 750 V; with a tractive effort of . The locomotive is fitted with both rheostatic and regenerative braking, in addition to standard westinghouse air brake equipment. An electrical train bus is fitted to enable two locomotives to work in multiple formation, either double-heading or push-pull train with a Driving Van Trailer or DBSO. To reduce the possibility of locomotive failure in the Channel Tunnel, most of the electrical systems are duplicated. 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「British Rail Class 92」の詳細全文を読む スポンサード リンク
