The building is located east of the Mittelkalbach district . It takes up two tracks that can be driven on at 250 km / h.

The gradient rises in the tunnel in a southerly direction with 12.5 per thousand.

To the north, after a short open section, the Kalbach tunnel follows . The Kalbach valley bridge connects to the south. This is followed by the Landrückentunnel , the longest railway tunnel in Germany.

history

The contract for the tunnel was awarded at the end of 1982.

When the tunnel was attacked on May 31, 1983, a total of twelve tunnels on the first two new German lines were under construction.

The structure was driven using the New Austrian Tunneling Method . Completion was (status: 1983) planned for June 1985. The planned construction costs were around 35 million D-Marks .

The tunnel was commissioned as part of the southern section of the line in 1988.

outlook

The preferred variant of the upgraded and new line Hanau – Würzburg / Fulda – Erfurt is to be linked to the existing high-speed line near Mittelkalbach.
