Siegstrecke
Emil Langen, board member of the Rhenish Railway and director of Friedrich-Wilhelms Ironworks in Troisdorf (now the location of the suburb and station of Troisdorf-Friedrich-Wilhelms-Hütte), finally implemented a change in the planned route north of Beuel. The new route went northeast from Beuel, crossing the Sieg river at Menden (now part of Sankt Augustin). A station would be built at the Friedrich-Wilhelms works and the line would then turn southeast to parallel the Sieg Railway to Siegburg.
