View of the Rudersdorf Tunnel

story
Due to the difficult topography and the limited technical possibilities, a direct connection between the train stations Siegen, Haiger and Dillenburg was not yet possible at the time of the construction of the Deutz-Gießener Bahn from today's Cologne-Deutz to Gießen in the 1850s. The direct connection between Siegen and Haiger was not completed until 1915. Work on the tunnel also ended on July 2, 1915. [2] This was especially important for the coal traffic leading south from the Ruhr area. This shortened the route by around 30 km. The most elaborate engineering structure to create this connection was the Rudersdorf Tunnel. The originally planned four-track expansion of the line between Siegen and Dillenburg, which would have required a second tunnel, did not come about due to the First World War.Source Wikipedia
