The VAG Class DT2 is an electric multiple unit (EMU) train type operated by the Verkehrs-Aktiengesellschaft Nürnberg on the Nuremberg U-Bahn system. It is a derivative of the MVG Class B, in service on the Munich U-Bahn since 1981.

The Nuremberg U-Bahn is a rapid transit system run by Verkehrs-Aktiengesellschaft Nürnberg, which itself is a member of the Verkehrsverbund Großraum Nürnberg. The Nuremberg U-Bahn is Germany's newest metro system, having begun operation in 1972, although the Nuremberg-Fürth route (U1) uses part of the right of way of the Bavarian Ludwig Railway, Germany's first passenger railway opened in 1835. The current network of the U-Bahn is composed of three lines, serving 49 stations, and comprising 38.2 kilometres (23.7 mi) of operational route, making it the shortest of the four metro systems in Germany, behind Berlin, Hamburg and Munich.
