Map with all coordinates: The Oberstaufen tunnel is the only railway tunnel on the Munich – Lindau railway line .
parameter
The tunnel is located a few dozen meters south of Oberstaufen station ( route kilometers 101.3). Today it is 144 meters long and the only tunnel along the route.
history
The tunnel and route were built as part of the Ludwig-Süd-Nord-Bahn . The plans initially envisaged the construction of the tracks around the Staufen mountain , but since there was no railway tunnel south of the Danube in the Kingdom of Bavaria , King Maximilian II ordered this tunnel to be built. The tunnel was originally 124 meters long. The section from Immenstadt to Oberstaufen, in which the tunnel is located, was opened on May 1, 1853. The tunnel profile was chosen to be appropriate for the operation at the time, but relatively narrow. It was also irregular: it fluctuated between 43 and 56 m² . From the end of the 20th century, the narrow cross-section meant that the line was subject to significant operational restrictions. So neither double-decker cars nor container trains could run. The latter is important because the Allgäu Railway is an alternative route if the partially single-track Arlberg Railway is disrupted .
Expansion in 2016
In 2016, the tunnel was fundamentally rebuilt and refurbished: First, the tunnel cross-section was increased considerably to 70 m². This now allows double-decker cars and loaded container cars to pass through . It received new interior cladding and porches that extend the original tunnel by 20 meters.
Due to difficult geological conditions both inside the tunnel and in front of the northern tunnel exit, the completion of the construction work was delayed by almost two months. The tunnel was opened to the first trains on December 7, 2016 and to all traffic on December 11, 2016. The cost of the measure, including a 9.5 km long route renovation with three bridges and the reinstallation of four points in the Oberstaufen station, amounted to € 25 million.
