Map with all coordinates: The Schönberg-Langeck Tunnel is one of a total of twelve tunnels on the Mannheim – Saarbrücken railway line that emerged from the Palatinate Ludwigsbahn and is the second longest after the Heiligenberg Tunnel .
location
The tunnel is located in the district of Weidenthal in the southeastern area between the Weidenthal and Neidenfels train stations . It is used to shorten a loop of the Hochspeyerbach . In front of the north portal this is crossed by a bridge. The south portal is adjoined by another bridge structure, which crosses the railway line twice over the said river and between the federal highway 39 .
history
On December 21, 1837, the Bavarian King Ludwig I gave the approval for the construction of a main line in an east-west direction from the Rheinschanze to Bexbach . Between Neustadt and Frankenstein numerous hills and foothills had to be conquered for the ascent. Among them was the Langeck ridge south of Weidenthal, the northeastern foothills of which opposed the planned route like a wedge. This required the construction of a 366-meter-long tunnel in this area, which was also the longest within this section. Traffic from Ludwigshafen to Neustadt had already been opened in 1847, and in 1848 the Homburg – Frankenstein section followed in two stages . On August 25, 1849, the gap between Frankenstein and Neustadt including the Schönberg-Langeck-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 Schönberg-Langeck 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.
