The U2 is a line of the Hamburg U-Bahn which has a length of 24.543 kilometres (15.25 mi).

[1] The first part of the line was opened on 21 October 1913 from Schlump to Emilienstraße.

[1] In 2009 eastern parts of U2 and U3 lines were swapped behind Berliner Tor.

Since then, it ends in Mümmelmannsberg, and the U3 became a ring line again with a branch to Wandsbek-Gartenstadt.
