Map with all coordinates: The Roßberg tunnel (in the planning phase also the Pfaffenstein tunnel ) is a 2,164 m long railway tunnel on the high-speed line Hanover – Würzburg in Würzburg .
It crosses under the Roßberg near Würzburg with an overburden of up to 80 m and therefore bears his name. In addition, the Pfaffenberg is crossed south of the Roßberg. The tube accommodates two tracks on a ballasted superstructure, which are planned to be driven on at speeds of up to 160 km / h.
course
The north-west portal of the tunnel is at 322.6 kilometers , the south-east portal at 324.8 kilometers.
The route lies in the area of the north portal in a right-hand curve of 11,000 m radius and then turns into a straight line. The gradient increases from the adjacent Maintal Bridge coming first with 12.5 per thousand and is shortly thereafter in a gradient of 12.5 per thousand.
The Veitshöchheim Main Valley Bridge connects to the northwest, and the Steinberg Tunnel follows a short bridge to the southeast .
history
planning
In the planning and construction phase, the tube was located in construction kilometers 306 to 308 of the route.
At the end of 1977 the planned length of the tube was 2142 m. The route should go south from a right curve of 10,000 m radius into a straight line. A gradient of 12.5 per mille should be followed by a gradient of 9 per mille.
construction
For the construction of the tunnel, a window gallery was first driven, from the end of which it was driven in both directions. The overburden was transported over the window tunnel by a conveyor belt, loaded onto a truck and transported to a landfill via construction roads .
At the end of October 1984, construction work began on the window gallery on Wilhelm-Wien-Strasse. In March 1985, driving began from the end of the window tunnel in a south and north direction. The attack was celebrated on June 12, 1985. The tunnel was also known as the Franziska Tunnel during the construction phase .
At the beginning of June 1985, 270 m to the north and 230 m to the south had been driven. The breakthrough in the south was expected for the end of August 1985, and the breakthrough in the north in mid-1986. By the end of August 1985, 700 meters of tunnel had been driven from the end of the window gallery towards the Main and 659 towards the Dürrbachtal.
The construction of the tunnel, which was continuously above the water table, was considered to be comparatively easy. Mainly Middle Muschelkalk was passed through . Most of the overburden was removed with excavators, only in a few cases explosives were used. The rock masses were transported to the surface via a conveyor belt in the window tunnel and then loaded onto trucks that carried the material away via non-public roads. The outbreak was deposited on the landfill at Ziegelhüttengraben near the Neumann barracks in Veitshöchheim .
The tunnel was ceremonially broken through on March 12, 1986.
The Roßberg Tunnel / Steinberg Tunnel consortium of six companies under the technical guidance of the Austrian company Monierbau was commissioned with the construction .
business
The tunnel was opened to traffic in May 1988 with the southern section of the line.
In June 1999, two young people were injured while trying to lower an iron chain onto the overhead contact line at the tunnel.
On December 23, 2014, part of an ICE train on the way from Hamburg to Munich stopped for two and a half hours in the tunnel due to personal injury.
technology
The south portal takes retract - distant signals for the central station Würzburg on. In the northern area of the tunnel are the advance signals for the Neuberg transfer point. In addition, the structure takes on four block identifiers .
