From Wikipedia, the free encyclopedia
The Heiligenberg Tunnel is the longest of a total of twelve tunnels on the Mannheim-Saarbrücken railway and the longest in the Palatinate. The tunnel crosses the Palatine Watershed in the German state of Rhineland-Palatinate. It was originally built for a single track, but a second track was built a few years later.
