Total length: 31.8 km (underground) - 40 stations

Large-profile line with ~100 m long platforms (6-car trains of F and H stock).

Line U7 operates every 4-5 minutes.

Running below ground for approximately one hour, line U7 is Berlin's longest metro line. Its oldest part is the stretch through Kreuzberg/Neukölln from Mehringdamm to Grenzallee, which opened in the 1920s as a branch of the former line C (now U6). In 1966, line U7 became a separate line and was subsequently extended at the both ends. The western extension runs through Schöneberg, Wilmersdorf and Charlottenburg and eventually reached Spandau in 1984, at a time when there was no S-Bahn service to this area. Line U7 turned out to be an important cross-city line in what was formerly West Berlin.
