List of the longest tunnels in Germany

from Wikipedia, the free encyclopedia

This list shows the longest road and rail tunnels in Germany.

Road tunnel

  • over 1.0 kilometers in length
  • If there are several tubes, the longest tube is decisive for the specified tunnel length
  • If an opening date (commissioning) is documented by sources, the year of completion is not mentioned here, but the year of opening
  • Column R indicates whether it is a two-tube tunnel or a single-tube (with two-way traffic)

Planned rail tunnels

The realization of the following tunnel projects is very likely. If these tunnels are built, they would move up this list:

There are project studies or requests from citizens' initiatives for the following tunnel projects, the realization of which is still uncertain:

S-Bahn tunnels and other rail tunnels

  • Underground and light rail tunnels are not taken into account, as different building regulations apply to them
  • Duplicate entries in comparison to the railway tunnel section are possible if the S-Bahn tunnel is also used by regional or long-distance trains
  • For branches in the tunnel (side branches), the total length of the tunnel (total coverage including the side branches) is given in the separate column
  • For later extensions and extensions of a tunnel, the length specification refers to the time after the extension
  • If an opening date (commissioning) is documented by sources, the year of completion is not mentioned here, but the year of opening

Planned S-Bahn tunnels

The following S-Bahn tunnel projects are to be implemented in the coming years:

  • Existing tunnel at Stuttgart Airport : It is planned to extend the Stuttgart-Rohr – Filderstadt railway line by 3.9 km to Neuhausen auf den Fildern . This would also extend the existing tunnel by around 500 meters to the east, i.e. to a length of around 4.62 km. Construction is scheduled to start in 2022.
  • Tunnel Erding , length: 2.295 km (main line) or 3.017 km (total coverage including side branch "Tunnel Wasserturm" = connection to Walpertskirchner Spange), part of the Erdinger Ringschluss project . The start of construction is planned for 2022, the completion for 2028 (main line) and 2030 (side branch).
  • Tunnel for the Nordmainische S-Bahn , side branch with a length of 1.77 km, which unthreads from the existing line ( City-Tunnel Frankfurt ) east of the Frankfurt (Main) Konstablerwache station, construction will start around 2022.
  • Tunnel for the S21 line (Berlin) , total extension length after all three planned construction phases have been completed: 2.8 km, starting (north portal) around 600 meters north of Berlin Central Station , south portal at the level of Mendelssohn-Bartholdy-Park underground station; Route: Nordring - Perleberger Brücke - Hauptbahnhof - Potsdamer Platz - Gleisdreieck underground station - Berlin Yorckstraße station , completion of the first construction phase from Nordring to the main station (three tunnels with a length of 609, 410 and 190 meters): 2021, completion of the entire route: approx 2035.
  • (So ​​far only in the preliminary planning stage :) Englschalking Tunnel: Length approx. 3 km between Munich-Daglfing and Munich-Johanneskirchen, part of the four-track expansion of the S-Bahn line to Munich Airport .
  • (So ​​far only in the preliminary planning stage :) Second Leipzig City Tunnel (east-west tube): length approx. 7 km.
  • (So ​​far only in the preliminary planning stage :) S-Bahn tunnel from Hamburg Hauptbahnhof to Hamburg-Altona .

  1. ↑ The tunnel on the main S-Bahn line in Stuttgart is divided into the following sections: The section from the main train station to the Neckar Bridge or to the Stuttgart North station is an extension of the existing tunnel of the connecting line (8,788 meters) as part of the Stuttgart 21 project and is currently under construction. On the section currently under construction, the tunnel coming from the main train station merges into a trough at the Stuttgart Mittnachtstraße train station . To the northeast of the station is the Rosenstein S-Bahn tunnel with a length of 1,170 meters. Due to the fact that the tunnel is interrupted by the trough at the Mittnachtstraße station, only the section Österfeld - Mittnachtstraße (= 9,818 meters) is considered as an independent tunnel in this list. This length of the main line results from the addition of 5625 m + 3163 m + 1149 m, minus 119 m = 9818 m. Because the end of the previous tunnel of the connecting line (the existing tunnel ending shortly after the main train station before the Stuttgart 21 project was implemented ) is at a distance of −0.498 kilometers. The connection of the new tunnel in the direction of the new Mittnachtstraße station takes place at route kilometers −0.379, so that the difference between 498 and 379 has to be deducted for the calculation of the main line length. Together with the Rosenstein S-Bahn tunnel, this results in a total tunnel distance of 9,818 + 1,170 = 10,988 meters. For the length information, the construction progress information from Deutsche Bahn and the planning approval documents for Stuttgart 21 (Section 1.5) were used.
