Map with all coordinates: The Höhnberg tunnel is an 824 meter long railway tunnel on the new Ebensfeld – Erfurt line in the Upper Franconian community of Grub am Forst between the route kilometers 100.301 and 101.125.
The structure takes up two tracks on a slab track that can be driven on at 300 km / h.
course
The structure crosses under the Höhnberg, south of Grub am Forst . It has a maximum coverage of 25 meters. The tunnel crosses the Füllbach tunnel on the Niederfüllbach connecting curve . The distance between the two tunnels is 16 m.
Immediately to the north is the Füllbach valley bridge . To the south, after the Niederfüllbach junction, the Weißenbrunn am Forst valley bridge follows . The cut in the terrain in front of the southern tunnel portal was fenced off.
The design speed is 300 km / h, the gradient has longitudinal inclinations of up to 9.7 per thousand.
construction
The Höhnberg tunnel, together with the Füllbach tunnel and the Füllbach valley bridge, is part of the nearly two kilometer long construction section of the Füllbach valley bridge / Coburg Süd connection.
The tunnel was ceremoniously opened on September 27, 2011 as the last of a total of 25 tunnels on the new lines. The tunnel sponsor is Katja Hessel , State Secretary in the Bavarian State Ministry for Economic Affairs, Infrastructure, Transport and Technology . The investment costs were given at the beginning of 2011 at 23 million euros. In November 2011, 100 m had been driven.
After 309 days of tunneling and using 59 t of explosives, the breakthrough at the north portal was on July 2, 2012.
The official breakthrough celebration followed on August 3, 2012. It was the 25th and last tunnel breakthrough of the German Unity Transport Project No. 8 . On this occasion, an “open construction site day” was celebrated at the neighboring Füllbach tunnel.
The double-track tube was built using mining techniques from south to north. A total of around 199,000 m³ of excavated material was produced. This was stored at the Pfarr landfill , which is located above the northern end of the tunnel ( 50 ° 13 ′ 6 ″ N , 11 ° 0 ′ 21 ″ E ). The inner tunnel shell was manufactured from the south portal towards the north portal.
On May 6, 2013, 211 cubic meters of concrete were placed in the last vault segment. Federal Transport Minister Peter Ramsauer and Railway Director Rüdiger Grube were among the guests at the celebrations . At the same time, the last segment for all 25 tunnels of the new lines of the Nuremberg – Berlin project was completed. The shell should be completed by the end of 2013 (as of August 2012). The tunnel was released in 2017 when the new line was opened.
