The Siemens-Düwag U2 is a type of light-rail vehicle (LRV). The cars were built by consortium of Siemens, Wegmann & Co. and Düwag. The U2 design was built on the Siemens U1 prototype tram built in 1965 (now stored at a Frankfurt tram museum). Originally designed for and used by the Frankfurt U-Bahn, the model of car was adopted for light-rail use by transit systems in Edmonton, Calgary, and San Diego, during a period in which few purpose-built trams were being manufactured. All U2 cars were built between 1968 and 1990. ==Technical details== The U2's dimensions are by by . In the US, usually up to three U2 cars are coupled to run as a train. Each articulated car has a total passenger capacity of 264 passengers. It may be equipped with two DC motors for a total power output of and a maximum speed of , or with four AC motors for an output of and speed of . As the length of a tram or light-rail train running on shared track is restricted to a maximum of 105 meters in Germany, up to four U2 cars may be used in a single consist on such track. Frankfurt U2 cars use Scheren (diamond) or single-arm (z-shaped) pantographs, while Calgary, Edmonton and San Diego vehicles use a single-arm (z-shaped) pantograph. * Manufacturer: Düwag Düsseldorf, West Germany * Type: Double-ended articulated car, 6 axle, multiple-unit operation * Height: * Width: * Length: , or * Weight (empty): , or * Car Body: Lightweight welded steel * Wheels: Steel-tired with acoustic dampening * Dynamic Braking * Speed: * Overhead Traction Power: 600 V DC 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「Siemens–Duewag U2」の詳細全文を読む スポンサード リンク
