Stammstrecke 2 (Munich U-Bahn)

The Stammstrecke 2 of the Munich U-Bahn is one of three main routes in the subway network of the Bavarian capital Munich. It runs from north to south, as well as east, and is currently operated by the underground U1 and U2 lines. Since 12 December 2011, the U7 line runs during high traffic times and since 15 December 2013 the U8 line assists on Saturdays. The U1 and U2 lines only run together on one route, in the central inner city area, before and after that, they are branched away from each other. The main line 2 has a total length of 33.8 kilometers and 38 underground stations. It runs exclusively in the city of Munich and completely in the tunnel.

The construction of the Stammstrecke 2 began in 1971. In October 1980 the first section was opened between Scheidplatz and Innsbrucker Ring. In the following years, eight route extensions were carried out. The current expansion state was achieved in 2004. Further construction is possible, but not planned at the moment.
