Stammstrecke 1 (Munich U-Bahn)

The Lindwurmtunnel (section between Sendlinger Tor, including Goetheplatz station) was built as early as 1938-41 as part of a north–south rapid-transit railway line, which is essentially today's course of the U6.

The section through Partnachplatz and Westpark to Holzapfelkreuth was opened for the International Horticultural Exhibition (IGA) on 16 April 1983 as a flower line.

From 28 October 1989, it was possible to travel from the Implerstrasse underground station to the former end terminal of Forstenrieder Allee.

The previous tram line 16 (Harras - Ratzingerplatz - Fürstenried) had served its purpose and was constructed and extended in stages.

Further route extensions in the south to the Klinikum Großhadern (on 22 May 1993) and in the north to Fröttmaning (on 30 June 1994) and further to Garching-Hochbrück (on 28 October 1995) followed.

The current station is completely roofed in and now also has an access at the northern end, which connects directly to the esplanade of the Allianz Arena.

MVG is commissioned with the operation and lease track facilities, railway stations and two long-distance trains from Garching.

Via Bonner Platz, the Münchner Freiheit station is reached, where the route joins the common U3 / U6 main line.

The station at Forschungszentrum, which is located at a low elevation, connects the adjacent research center to it by rail for the first time, shortly thereafter the U6 comes to the surface for about 500 meters.

At the Marienplatz station, designed by Alexander von Branca, the S-Bahn lines S1-S8 are crossed, and due to the occupation and stadium traffic, it is often overloaded.

Therefore, and in view of the 2006 Football World Cup, the city council decided that "under its feet", directly under the town hall, two additional pedestrian tunnels should help equalize the crowd.

At the Implerstraße station, the U3 and U6 lines separate again, here there is also, in the opposite direction, a single-track branch to the plant Theresienwiese, over which the route of the U4 / U5 is reached.

The next station, Brudermühlstraße, was built together with the overlying Brudermühltunnel of the Middle Ring, which is why it lies relatively deep in the groundwater.

On the south side, a ramp leads from the underground station to the mezzanine level and continues towards the Isar and Zoo.

Obersendling was the first station in which the planners of the subway unit left the bored pile walls open as a design element, painted in reddish brown.

The following station, Aidenbachstraße, is characterized by twelve broken mirror surfaces, which are arranged according to the center pillars.

Similar to Obersendling, the bored pile walls were painted burgundy red at the now following Machtlfinger Straße station, and decorated with art objects from Rupprecht Geiger.

The next station, Forstenrieder Allee, is similar to the one on Aidenbachstraße, but shows pictures by the artist Helmut Pfeuffer.

On Basler Straße, the cartoonist Ernst Hürlimann has immortalized himself in the form of a red devil, alluding to figures of the Basel Fasnacht.

In the further course of the route, the end station at the Klinikum Großhadern is reached via Haderner Stern and Grosshadern, whose access to the surface is visible in the form of two glass pyramids.

It runs in a north–south-westerly direction from Garching-Forschungszentrum via Fröttmaning, Münchner Freiheit, Odeonsplatz, Marienplatz, Sendlinger Tor, Implerstraße and Harras to the Klinikum Großhadern.

The U6 operates as the only line weekdays outside rush hours, and on Saturdays during the day in a quicker tackt between Münchner Freiheit and Harras (every 3/7 minutes), in order to stay track with the U3, with a tackt[check spelling] timing of 3/3/4 minutes, in order to compensate the high number of passengers.

An extension of the U3 in the north, via Moosach and further to the, opened in 2005, S-Bahn station Untermenzing, was in the traffic development plan 2006 of the city of Munich as a "corridor for network supplementation".

Since the northern end of the U6, the Garching-Forschungszentrum station, is already located directly on the border to the district of Freising, an extension to the north, to the S-Bahn stops Neufahrn, Eching or even the airport was required (see Regional Plan Munich 2004).

While the study showed, as expected, that these plans did not replace a rapid transit or express train connection between Munich Hauptbahnhof and the airport, it concluded that the networking of the U6 and S1 would bring many benefits.
