Map with all coordinates: The Kehre tunnel is one of a total of twelve tunnels on the Mannheim – Saarbrücken railway that emerged from the Palatinate Ludwig Railway . Originally laid out as a single track, the line was expanded to double tracks a few years later.
location
The tunnel crosses under the eponymous Kehrfelsen and is located in the area of the local community Frankenstein (Palatinate) . Not far from its north portal, Bundesstraße 37 runs parallel to the railway line. Immediately after the south portal, the street is crossed by means of a viaduct.
history
The construction approval for the main line in east-west direction from the Rheinschanze to Bexbach took place on December 21, 1837. Between Neustadt and Frankenstein numerous hills and foothills of mountains had to be overcome for the ascent. Among them was the sweeping rock. This required the construction of the 302 meter long tunnel in this area. Traffic from Ludwigshafen to Neustadt had already been opened in 1847, and the Frankenstein – Homburg section followed in two stages in 1848. On August 25, 1849, the gap between Frankenstein and Neustadt including the Kehre tunnel was closed. Carriages had previously taken over the traffic between the two sections of the route. In July 1856, the Ludwig Railway was then consistently double-tracked.
Since the main line from Mannheim to Saarbrücken has always been of great importance for long-distance traffic, it was gradually electrified from 1960. The Kehre tunnel had to be widened for electrification. This delayed the completion of the electrical operation, which could finally be started on March 12, 1964 on the entire length.
