The Dietershan tunnel in the Fulda-Haune-Tafelland is a railway tunnel on the high-speed line Hanover – Würzburg in the Fulda district . With a length of 7,375 m, it is one of the longest railway tunnels in Germany .

course

The route of the Dietershan tunnel north-east of Fulda describes a gentle right-hand curve in a southerly direction. In its course, the tube , which leads through the eastern flank of the Mühlberg ( 435  m ) near Dietershan , crosses twice the federal motorway 7 and at the north portal of the tunnel, the state road  3378 ( Michelsrombach - Lehnerz ).

The gradient drops continuously to the south. In the tunnel, the route reaches the area of ​​the city of Fulda. The overburden, the thickness of the rock overlying a tunnel, is between 15 and 85 m.

The southern section of the tunnel lies in an arc of 2,500 m radius, which can be driven through at 160 km / h. To the south, after a roughly 280 m long earthwork section, there is a 620 m long underpass in which the new line will be threaded between the two tracks of the existing Fulda – Bebra line .

The tunnel runs through red sandstone interspersed with clay interlayers.

A transfer point with four points was set up in the tunnel .

history

planning

In the course of the options I and II considered as part of the regional planning procedure in 1974 and 1975, today's Dietershan tunnel was not planned. The route was to run further west at this height and without a tunnel and cross the Fulda northwest of Lüdermünd .

The tunnel was part of variant III of the four variants of the spacious lines of the new line in the Fulda area. In this variant presented in 1976, the tunnel was planned with a length of 6,970 m. In June 1977 the planned length was 6.5 km.

Preparatory explorations began in 1980 to determine the mountain conditions to be expected. In 1982, a 320 m long exploratory tunnel was built as part of a test drive. A cross-section of 18 m² was excavated over a length of 220 m, which was expanded to 65 m² in two 50 m long sections. The bench was opened in one of the widenings over a length of 35 m.

At the end of 1983 a tunnel length of 7,340 m was planned, in 1984 7,345 m or 7,330 m.

The construction was calculated in 1984 with a cost of 190.0 million DM. The construction period should run until April 1987.

The structure marked the southern part of planning section 16 of the central section of the new line.

construction

Construction work began in May 1983.

The tunnel was driven from both sides. After the north portal was posted on November 24, 1982, the south portal followed on July 26, 1983. According to their sponsors , the northern section was referred to as the Liselotte Tunnel during the construction phase and the southern section as the Gerda Tunnel .

The lengths of the tee-offs were between one and two meters for the dome tunneling and between one and four meters for the bench tunneling.

Construction work ended in May 1987.

A working group of Holzmann and Ed was commissioned. Branch. (Graz).

business

The first major rescue exercise on the new line took place in the Dietershan tunnel on June 12, 1989. A train came to a halt 500 meters from the tunnel portal. Out of 50 "travelers", 20 were assumed to be capable of self-rescue. A tunnel rescue train was also used .

At the end of 2011, wild trap fences were erected at both tunnel portals .
