Rheydt Hauptbahnhof is a railway station in Mönchengladbach, Germany. Mönchengladbach is the only city in Germany that has two stations called Hauptbahnhof, due to the merger of the city of Rheydt into Mönchengladbach in the late 1970s.

The Aachen–Mönchengladbach railway is a main line in the German state of North Rhine-Westphalia. It is an important link between the Ruhr and Belgium for freight trains and is served by regional passenger trains. The line was built by the Aachen-Düsseldorf-Ruhrort Railway Company and is one of the oldest lines in Germany, which was opened between 1852 and 1854.
