 in 1921 it was even proposed to demolish the already existing tunnel. However building continued, so on 30 January 1923 the first tunnel section was opened, between Hallesches Tor and Stettiner Bahnhof (since 13 December 2009 Naturkundemuseum, previously Zinnowitzer Straße). A further section was opened on 8 March 1923 between Stettiner Bahnhof and Seestraße. At the Seestraße station a maintenance workshop was built.

At the junction Mohrtunnel, Friedrichstraße it came to the first intersection of two subway lines (north-south railway and the so-called " Centrum line )". But 160 metres away the city of Berlin built its own station named Leipziger Straße (now Stadtmitte), also because the principle of the Turmstraße

Belle-Alliance Straße station was built with three tracks. From the western track (side platform), the trains ran to Tempelhof and Neukölln, held at the central platform for trains from Neukölln (middle track) and Tempelhof (eastern railway) towards downtown.

.

Due to disputes with Tempelhof the first route to be built was to Neukölln. Work on the other branch only began in 1924. Two years later, on 14 February 1926, the Belle-Alliance-Straße - Kreuzberg (now Platz de Luftbrücke) branch was opened. A year later it reached the airport (now Paradestraße). East of the track is the site of the Tempelhof Airport.

In 1929 the line reached the S-Bahnhof Tempelhof the Ringbahn, which has a large ticket hall for both S and U-Bahn. Since the subway station had to be very deep, this depth could be used for a spacious hall.

In the North

Similar to the construction of the current line U7 in the direction Rudow here was this river, the biggest problem on the track. They chose one of the few structures used in Berlin: The Metro leads in the bridge over the Teltowkanal. The bridge consists of two adjacent buildings to the street above it. Part of the eastern half of the bridge is built to fit that into this underground station Ullsteinstraße. Something had to be met but for the vessels, the vertical clearance of 4.6 meters, they built for the road ramps. The street level is through this structure 1.2 meters above the original level.
South of the Teltowkanal follows the U-Bahn Mariendorf to the terminus Alt-Mariendorf, which was built at the junction of the road with the Peace and Reißeckstraße Mariendorfer Damm. From this starting point, several bus routes in the sparsely developed area. With this expansion, which now U6 was completed. Further extensions are planned.

Apart from the station Alt-Tempelhof were all the stations designed by Rainer G. Rümmler. As with the southern U7 he used this large rectangular ceramic tiles.

After the Fall of the Berlin Wall, the rehabilitation and reconstruction of the platforms and tunnels have been carried out. All stations were closed on 1 July 1990 opened.

Were built before the small-profile stations equipped ornately, were the stations of the U6 only white plaster as a disguise. The only distinguishing feature was the characteristic colors of the columns and station signs. The length of the platforms has been reduced. Are common in the later buildings platforms 110-120 meters, at that time were only 80-meter platforms built. Back in the 1970s, there were first capacity problems because you could only use 4-car trains. Therefore, in the 1960s and 1970s transformed the West Berlin subway stations and increases the platforms, so there could hold longer trains. But since the three border stations, Friedrichstraße
