The Siemens-Düwag U2 is a type of light-rail tram 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 {{convert|24.284|m|ftin|abbr=on}} by {{convert|2.650|m|ftin|abbr=on}} by {{convert|3.66|m|ftin|abbr=on}}. In the US and Canada, usually up to five U2 cars are coupled to run as a train. Calgary Transit regularly couples up six U2 cars to shuttle them from Anderson Garage to Haysboro storage. These unique shuttle trains can be commonly seen after the evening rush hour. 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 {{convert|300|kW|abbr=on|lk=on}} and a maximum speed of {{convert|80|km/h|abbr=on}}, or with four AC motors for an output of {{convert|544|kW|abbr=on|lk=on}} and speed of {{convert|88|km/h|abbr=on}}.

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.

Variants

Siemens–Düwag Type U3 is an upgraded version of the U2 with a slightly longer length and cosmetic changes. Introduced in 1977, they entered service in 1980 and were never exported outside of Germany's Frankfurt U-Bahn.

Siemens–Düwag Type U2A on Sacramento Regional Transit's light rail system is an upgraded version of the U2 that shares similar characteristics of the newer SD-100s and SD-160s, yet it still uses the mechanical equipment of the U2.
