The Siemens-Duewag Supertram is a fleet of 25 trams built by Siemens-Duewag of Düsseldorf, Germany, in 1992 for use on the Sheffield Supertram light rail network in England. They were the only trams in use on the network until the entry into service of British Rail Class 399 tram-trains in 2017. As of May 2020, all 25 remain operational.
