Landrücken Tunnel

The Landrücken Tunnel is a railway tunnel on the Hanover-Würzburg high-speed rail line. With a length of 10,779 metres (35,364 ft) it is the longest tunnel in Germany.

Geography

The tunnel is in east Hessen between the stations of Fulda and Würzburg. Between the northern tunnel entrance of Kalbach (50° 24′ 22″N, 9° 39′3″E) and the southern end at Mottgers (50° 18′35″N, 9° 39′47″E) it crosses the Landrücken range which forms the Rhein-Weser drainage divide dividing the river basins of the Fulda and Main.

Description of tunnel

The double-track Landrücken Tunnel was built using the New Austrian Tunnelling method working from the north portal, known as "Baulos Nord" and two side accesses ("Baulos Mitte" and "Baulos Süd"). In addition, three shafts were established for ventilation during tunnel boring.

The tunnel opened in 1988 with a total tunnel cross section of 100 to 110 square metres (1,100 to 1,200 sq ft) and a maximum 1.25% gradient. It surpassed the Kaiser-Wilhelm-Tunnel near Cochem as the longest railway tunnel in Germany.

Outside the north portal of the tunnel, at 380m altitude is the summit of the Hanover-Würzburg high-speed rail line.

Accidents
The ICE power head 401 511 after the collision. The photo was taken three days later at the operational train station of Mottgers, after the powerhead had been recovered.

On April 26, 2008, ICE train 885 was on its way from Hamburg to Munich with 170 people on board. At 9:05pm, it collided with a herd of sheep that had strayed into the tunnel. The train derailed at 215 kilometres per hour (134 mph) inside the tunnel. 25 people were injured, 12 of the 14 cars were derailed.[1]

Distelrasen-Tunnel

A few kilometers west of the Landrücken Tunnel, the Distelrasen-Tunnel built in 1914, near Schlüchtern-Elm on the Kinzig Valley Railway, was the first railway to traverse the Landrücken drainage divide.

gollark: And seems fairly competitive, even.
gollark: … ADL has been here for several months?
gollark: The networking stuff is actually quite important. Apparently their silicon photonics stuff can save a lot of power in high speed switches.
gollark: Also fabrication. They're opening that to other companies.
gollark: Also FPGAs.
