The Pulverdinger Tunnel is a 1,878 m long railway tunnel on the high-speed line Mannheim – Stuttgart . It is partly in the area of the hamlet of Pulverdingen in the town of Vaihingen an der Enz and therefore bears his name.

course

The tube lying between the route kilometers 84.17 and 86.04 has a maximum overburden of 33 m. It passes through layers of the Lettenkeuper and the Upper Muschelkalk . During the construction phase, which ran from 1986 to 1988, around 210,000 m³ of excavated material were produced. The construction costs were around 41 million Deutschmarks .

In the area of the north-west portal, the route initially lies in a left-hand curve that turns into a straight line. The gradient rises from this portal (upper edge of the rail at around 260 m) initially with 12.434 per thousand, later (from 84.906 kilometers of route) this gradient flattens to 10.590 per thousand, before the southeast portal on Markgröninger markings is reached with a height of around 280 m.

The cross-section has a clear width of 12.80 to 13.40 m. The clear height (above the upper edge of the rail) is between 7.75 and 8.42 m.

The structure lies largely in layers of the Upper Muschelkalk , in places also in Trigonodus dolomite and Lettenkeuper .

history

planning

According to the planning status of 1973, an approximately 2.2 km long tunnel was to be built under a ridge between the Enz and Glemstal bridges.

According to the planning status from the end of 1977, the structure was planned with a length of 1700 m. A tunnel portal should be 150 meters away from the house of an Aussiedlerhof .

In the course of the 135 million DM package agreed in November 1978 between Federal Transport Minister Kurt Gscheidle and Baden-Württemberg's Prime Minister Lothar Späth , the tunnel was extended by 200 m and the pre-cut shortened accordingly. The planned additional costs of this measure were around 5.5 million DM.

The structure with its length of 1,878 m, which was realized later, was planned as early as the beginning of 1983.

construction

With an excavated cross-section of 105 to 118 m², a useful cross-section of 82 to 94 m² was created.

The ARGE Pulverdinger Tunnel , which was formed from the companies Alfred Kunz (Munich) and C. Baresel (Stuttgart), was commissioned with the construction . The tunnel sponsorship had taken Christa Schulte.

The estimated shell construction costs were given around 1984 at 40.7 million DM.

business

On August 22, 2010, an ICE stopped in the Pulverdinger tunnel due to an engine failure. Four passengers had to receive medical attention due to circulatory problems.
