The Dortmund–Soest railway is a line in the German state of North Rhine-Westphalia. It runs from Dortmund Hauptbahnhof through the southern Dortmund district of Holzwickede to Unna and from there through the Hellweg Börde parallel to the Haarstrang ridge on the southern edge of the Westphalian Lowland via Werl to Soest. As the line was opened in 1855, it is one of the oldest railways in Germany.

Dortmund Hauptbahnhof is the main railway station in Dortmund, North Rhine-Westphalia, Germany. The station's origins lie in a joint station of the Köln-Mindener Eisenbahn and Bergisch-Märkische Eisenbahn which was built north of the city centre in 1847. That station was replaced by a new station, erected in 1910 at the current site. It featured raised embankments to allow a better flow of traffic. At the time of its opening, it was one of the largest stations in Germany. It was, however, destroyed in an Allied air raid on 6 October 1944.
