Landrucken Tunnel

The Landrücken Tunnel is a railway tunnel on the Hanover-Würzburg high-speed rail line. With a length of 10779 m 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 m2 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.
