course

The tunnel runs in the Upper Franconian district of Obersinn .

The route describes a continuous left curve with a radius of 6,000 m in a southerly direction . The gradient drops in a southerly direction at 12.0 per thousand.

It passes under layers of red sandstone with an overburden of up to 55 m .

The Dittenbrunn hillside bridge connects to the tunnel to the north, and the Obersinn valley bridge to the south .

The maximum overburden is 55 m.

history

planning

In the planning and construction phase, the tube was at construction kilometer 256.

At the end of 1977 the tunnel was planned to be 775 m long. The route and gradient already corresponded to the structure that was realized later. At the end of 1981 the planned length was 796 m.

construction

Construction work began in April 1981. A consortium of the Polensky u. Zöllner , Porr and Stuag .

The tunnel was posted on July 8, 1981. The tunnel sponsorship was taken over by Jutta Weigelt, the wife of Horst Weigelt , the then President of the Nuremberg Railway Directorate . It ran between construction kilometers 255.581 and 256.843.

It was knocked through on April 28, 1982 as the second tunnel on the new line during a ceremony. The tunnel godmother symbolically triggered the last blast at 4:57:43 p.m. Its length was still 796 m as at the end of 1983.

The structure was completed in December 1982. At the end of 1983, the tunnel was one of the first three tunnels in the southern section of the line, which had already been completed.

The 170,000 cubic meters of overburden from the construction were installed in the earthworks section to the adjacent Altengronauer forest. Another source speaks of 234,000 m³ excavated volume.

On August 17, 1981, a 45-year-old worker was run over by an excavator during construction. He later died in hospital.

The construction costs were given in 1982 with 24.5 million D-Marks (about 12.5 million euros ), the order value was given in the previous year at 19 million D-Marks (about 10 million euros).
