Map with all coordinates: The Schwarzenfelstunnel is a 2,120 m long railway tunnel on the high-speed line from Hanover to Würzburg . The tube is located around 25 kilometers south of Fulda , near the state border with Bavaria . It runs in the area of the Schwarzenfels district of the Hessian community Sinntal and therefore bears his name.
course
The route runs in north-south direction on the left side of the Sinntal. In the area of the north portal, it initially describes a right curve of 5450 m radius in a southerly direction, which merges into a straight line towards the south portal. The gradient falls in the tunnel with initially 12.5 per mille and after about the approach signal of the Mottgers train station with 2.0 per mille to the south.
The tube accommodates two tracks on a ballast superstructure, which can be driven on as planned at 250 km / h. The longest German tunnel, the Landrückentunnel , connects to the north, followed by the Mottgers depot to the south .
history
planning
The tube was attached to the south portal on September 20, 1982 . Among the guests were Federal Transport Minister Volker Hauff , Hesse’s Prime Minister Holger Börner and Federal Railroad Board Member Reiner Gohlke . The tunnel sponsorship had Vera Rüdiger adopted, the former Hessian Minister for Federal Affairs. The planned length was 2,120 m, the planned construction time was three years.
The planned cost of the 2,120 m long structure was 57 million DM. The breakthrough was expected for June 4, 1984, and completion (including rail technology) should take place in June 1985.
In the planning and construction phase, the structure was located in construction kilometers 246 and 248.
construction
At the north portal, around 70 m were built using the cut-and-cover method due to the low overburden and the rock conditions . The rest was built using the mining method ( shotcrete construction ). The coverage is only five to ten meters.
With a usable cross-section of around 86.5 m², an excavated cross-section of up to 145 m² was created. Around 440,000 m³ were excavated from the mountain and installed at the Schneefeld Heiners landfill .
At the end of 1983, more than half of the tunnel length had been driven. A length of 2,120 m was planned.
During the construction phase, the tunnel was between construction kilometers 246.162 (north portal) and 248.241 (south portal).
During the construction work, a previously unknown escape tunnel to Schwarzenfels Castle was discovered.
A working group of the construction companies Alfred Kunz and Kronibus Tunnelbau was commissioned . It was the third tunnel on the route built by the Alfred Kunz construction company .
An oil painting by Peter Tomschiczek shows the view from one of the two portal areas of the tunnel onto the adjoining open stretch of road.
