Soon 175 years of the burgberg tunnel

In the regnitz valley, which runs from south to north, the erlanger burgberg forms a barrier due to its east-west orientation. The nurnberg-bamberg trunk road and the ludwig-danube-main canal could still be passed on the narrow valley floor between the regnitz and the western slope of the mountain. When the nurnberg – bamberg railroad line was built as part of the ludwig-sud-nord railroad, there was no more room for a railroad line.
Therefore, in 1842, it was decided to build a tunnel through the castle hill, which lasted until 1844. In addition, king ludwig I.

The tunnel through the burgberg was the first bavarian railroad tunnel (length: 306.65 meters) and is today the oldest still in operation in germany. After its completion, the ludwig-sud-nord-bahn connected lindau on lake constance with hof on the border to saxony and had a total length of 566 kilometers. The inauguration took place on 25. August 1844, the first tarmac train ran on august 1, 1844. September of the same year.
In 1936, the tunnel was extended to accommodate the electric overhead line.
As is known, in the course of the four-track extension of the railroad line nurnberg-ebensfeld, a second tube was built next to the tunnel of 1844. With a maximum cover of 38 meters, it is also 306 meters long , to preserve the historic portal situation. The existing tunnel was also rehabilitated in the course of the tree removal work.
