History

U3 before line swap in 2009

The ring line was built from 1906 to 1912 and had a length of 17.48 km (10.86 mi) and with 23 stations. The first part of the line which was first opened in February 1912, was the part between Rathaus via Hauptbahnhof and to Barmbek. On 2 January 1967 the first part of the line to Billstedt opened with the section leading to Horner Rennbahn. Since then, the U3 line was not a ring line anymore until the year of 2009.

In 2009 eastern parts of U2 and U3 lines were swapped behind Berliner Tor. Before that, the U2 line led to Wandsbek-Gartenstadt. Since then, it ends in Mümmelmannsberg, and the U3 became a ring line again with a branch to Wandsbek-Gartenstadt.
