Map with all coordinates: The Niedernhausen tunnel is a 2,765 m long railway tunnel on the high-speed line Cologne – Rhine / Main . It runs in the area of the Hessian community of Niedernhausen and therefore bears his name.
course
In the tunnel, the route passes under Daisbach , the country road L 3273, the A 3 and the Taunus comb under the Ziegler head.
A trough is located in front of the north portal at km 138.0 . The gradient initially slopes down towards the south portal and rises again later. The route runs to the south in a straight line that turns into a left curve and finally into a straight line again. The south portal is at 140.8 km. The 484 m long Theiss valley bridge follows to the south .
At 50 ° 10 '17.5 " N , 8 ° 17' 6.1" O and 50 ° 10 '37.1 " N , 8 ° 16' 37.7" O lead exits from the tunnel to the surface.
In the northern section of the tunnel are the pre-signals for the Idstein transfer point , which connects to the north of the tunnel.
history
planning
In the regional planning procedure opened in February 1992 for the Hessian section, the then Deutsche Bundesbahn introduced a route proposal as a variant for Idstein Ost , which provided for a 2,700 m long tunnel in the Niedernhausen area. The alternative concept of the Idstein West variant , on the other hand, provided for a 1,930 m long Niedernhausen tunnel, the south portal of which, as in the eastern variant, would be located in the Königshofen area west of the motorway.
At the end of 1995 the planned length of the structure was 2765 m.
In the planning and construction phase, the tunnel was part of section C of the middle section of the new line. The tunnel is located in the plan approval section 32.4 of the new line (community of Niedernhausen and others), for which the plan approval decision was issued on October 9, 1996.
construction
At the beginning of 1997 a concrete mixing plant was built for the construction of the tunnel.
The tunnel was on 14 May 1998 as the penultimate tunnel of the new line in Hesse struck . The planned length was 2,765 m. The tunnel sponsorship was taken over by Anke Koch, the wife of the then CDU opposition leader in the Hessian state parliament, Roland Koch .
From a length of 2,765 m, 2,101 m were excavated by mining. In some cases, an elm tunnel with leading pipe umbrellas was used. The driving tunnel was created with an excavated cross-section of 140 to 160 m², a vertical smoke extraction shaft with a diameter of 5 m and a height of 53 m, an emergency exit shaft with a depth of 24.5 m and a diameter of 9.0 m and an inclined shaft with a cross-section of 24 m² a length of 126 m. Originally, the tunnel was to be driven completely underground using shotcrete , with an elm tunnel being planned in the northern section.
The tube was punctured on August 20, 1999. It was the sixth tunnel on the line in Hesse, at least the shell of which was completed.
More than 1000 people attended the Open Tunnel Day in April 2001. Visitors were guided through the tunnel on various routes. An exhibition at the south portal provided information about the construction of the structure. At this point in time, the rails for the future track systems had just been delivered.
business
On April 1, 2013 at around 8.45 p.m. ICE 528 on the way from Munich to Dortmund came to a halt due to damage to the pantograph and contact line at the level of the north portal. After a check by the train team showed that it was not possible to continue the journey, two diesel locomotives and a vehicle were requested to repair the catenary around 9 p.m. and arrived at around 10:40 p.m. A replacement train (multiple units 4610 and 353) arrived at around midnight, and around 400 passengers were transferred via footbridges. At about 1:15 a.m. this train left for Cologne. The train concerned was formed from the ICE 3 multiple units 318 and 327.
The rails in the tunnel should be changed in the second half of 2014.
A rescue exercise took place in the tunnel on the night of October 27, 2019. An ICE fire with around 500 participants was simulated.
technology
The detection system for non-round wheels ( DAfuR ), which is located in front of the north portal, is remarkable .
