context_page_description: The Siemens–Duewag U2 is a type of light-rail vehicle. The cars were built by consortium of Siemens, Wegmann & Co. and Duewag. The U2 design was built on the Siemens U1 prototype tram built in 1965.
  The name is derived from the class identifier given to the cars in the Frankfurt system.
  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.
context_section_description: San Diego MTS retired their last U2 vehicles in January 2015, coinciding with low floor S70 cars being deployed on its Blue Line, six examples are preserved by various museums and nonprofits. 
  San Diego Electric Railway Association (SDERA) - Car 1002, now on display in National City
  Southern California Railway Museum - Cars 1003 and 1008, operate regularly on the Museum system, independently and as a two-car train.
  Western Railway Museum - Cars 1017 and 1018, operate on museum excursions
  Rockhill Trolley Museum - Car 1019 operates regularly on the Museum system.
  MTS has retained Car 1001 as part of its heritage fleet of light rail vehicles.  The car was unveiled as part of a celebration at 12th & Imperial on July 11th, 2019, and re-entered service two days later. The car operates on the Silver Line, alongside San Diego PCC cars 529 and 530.
  The City of Edmonton has stated that at least one U2 will be preserved and operational for their historical fleet. The City of Calgary is currently looking into putting one on static display.
  Cars 303-305 of the Frankfurt system have also been preserved following retirement in 2016.
