The Osterberg Tunnel (also: Tunnel Osterberg ) is a railway tunnel on the new Erfurt – Leipzig / Halle line . The two single-track tubes of the structure are each 2082 m long.

The planned investments were 120 million euros .

Location and course

The tunnel lies between the route kilometers 248.928 and 251.010. The east portal is near Kalzendorf , the west portal near Karsdorf . The gradient rises with a maximum of 12 per thousand in an easterly direction. The Unstruttal Bridge connects to the two single-track tubes in the southwest .

The two tubes are connected to each other with four cross passages. There are rescue stations at both tunnel portals.

geology

Upper Buntsandstein , made up of marl , limestone , dolomite and silt , is passed through on the western 750 m . In the rest of the course, lower Muschelkalk was excavated. The groundwater is at the west portal at the level of the tunnel floor , the rest of the way below the tunnel.

history

planning

In mid-1994, the building was calculated at 155 million D-Marks net. It was to be awarded in one package together with the neighboring Unstruttal bridge. According to the planning status from mid-1995, the building should be between building kilometers 57.83 and 59.90 with a length of 2072 m.

As part of a plan change procedure, the number of crosscuts was increased from one to four in 2009 and the tunnel portals were supplemented by sonic boom structures to prevent the tunnel bang .

The tunnel is located in the planning approval section 2.3 of the new line.

construction

Construction work on the west portal and the Unstruttal bridge (2010)

In the second half of 2008, construction work began with the construction of an approximately 500 m long pre-cut at the east portal, in which the starting pit was created. Tunneling began with the ceremonial construction of the tunnel on February 18, 2009. The sponsorships were taken over by the Saxony-Anhalt Minister of Agriculture Petra Wernicke and Christine Bannert, the wife of the district administrator of the Saalekreis district, Frank Bannert .

Both tubes were driven simultaneously from the east portal in a downward direction towards the west. Mining production was carried out using shotcrete construction over a length of 2027 m . 40 m each at the west portal were created using the open construction method (vaulted cover construction).

Up to the beginning of August 2009, 1.3 km had been driven in both tubes. Both tubes broke through in mid-November 2009.

A total of around 600,000 m³ was excavated. This material was used to fill parts of an open-cast mine at a nearby cement works . The shell of the tunnel was completed in 2012.

A consortium made up of four Austrian companies was commissioned to build the two tubes . Up to around 120 people worked on the construction site. The executing companies were PORR , G. Hinteregger, Östu-Stettin and Jäger.

DB Netz was the client .

The tunnel was equipped with digital BOS radio . The Saalekreis receives three vehicles for the tunnel from Deutsche Bahn to support rescue operations.

A large-scale exercise with 600 participants was planned for September 19, 2015.

Information center

Front of the information center

The information center on the new line, which was previously set up at the west portal of the Finnetunnel near Herrengosserstedt, moved to the construction base at the east portal of the Osterberg tunnel near Kalzendorf in spring 2012 . It opened there on June 19, 2012 with expanded content. a. a virtual route trip from the perspective of a future train driver, archaeological finds and a section of the slab track and the overhead line to be installed.
