Nuremberg U-Bahn

The Nuremberg U-Bahn is a rapid transit system in Nuremberg and Fürth, Bavaria. It is operated by Verkehrs-Aktiengesellschaft Nürnberg (VAG; Nuremberg Transport Corporation), which itself is a member of the Verkehrsverbund Großraum Nürnberg (VGN; Greater Nuremberg Transport Network). 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.

In 2008, driverless and fully automated trains were introduced on the new U3 line, making it Germany's first automatic U-Bahn line. U2 was converted to driverless operation by 2010, the first such conversion anywhere in the world.
