The Massener Tunnel is a railway tunnel for freight traffic planned as part of the new and upgraded Karlsruhe – Basel line . The 1,956 m long tube is to be built west of the district of Mengen in the municipality of Schallstadt and therefore bears its name. It should accommodate two tracks and be able to travel at 160 km / h.

The plan approval procedure was initiated at the end of July 2019, and the plan approval decision is expected to be available in 2023 Template: future / in 3 years.

course

The tube is intended to cross under the Alemannenbuck , an elevation west of Mengen. It is part of the double-track freight train bypass of the Freiburg Bay (route 4280, km 209 and 210), which is bundled with the federal motorway 5 , which is being created in the course of the new and upgraded route . The route describes a left curve, parallel to the motorway to the east. The north portal is east of Tiengen , south of the Freiburg Süd motorway junction ; the south portal immediately south of the underpass of the district roads 4980/9862, west of Mengen.

The tunnel is necessary because the gradient of the railway line in this area cannot follow that of the motorway. It was chosen in such a way that the length of the tunnel is reduced to less than 2,000 meters and there is no need for an additional emergency exit.

The tunnel, which is flat below the site, is intended to cut through primarily loess . The planned overburden is between 2.5 and 13 meters and in large parts less than 5 meters.

Several emergency exits are planned to allow a maximum escape route of 500 m. Rescue stations are provided at both portals and at the emergency exits .

history

Around 1990, five variants with additional sub-variants were considered for the construction of the new and upgraded route in the Freiburg area. The tunnel is the result of the Freiburg bypass developed in the course of the preliminary planning in the Offenburg – Basel section for freight trains and special passenger trains that do not stop at Freiburg Hauptbahnhof. The regional planning procedure for two route variants between Kenzingen and Schliengen developed as part of the planning was applied for at the Freiburg Regional Council at the end of August 1993 . The tunnel was there part of the so-called proposal Street I .

The tunnel is located in the plan approval section 8.2 of the route and is to be built using the cut- and- cover method .
