Dortmund-Scharnhorst station is located between the Dortmund suburbs of Alt-Scharnhorst and Brackel in the German state of North Rhine-Westphalia on the Dortmund–Hamm line on Flughafenstraße.

During the construction of Dortmund Hauptbahnhof a freight rail bypass was built between Scharnhorst and Nette in 1903 along with the Scharnhorst marshalling yard, where a passenger station was initially established for railway staff.

At the western end of the station another and more modern pedestrian and cycle bridge also connects the two platforms together.

Dortmund-Scharnhorst station is served by the NRW-Express (RE 1, every second hour) and the Rhein-Emscher-Express (RE 3).

[5][6] The station is also served by bus route 420 (Scharnhorst – Derne + Brackel – Aplerbeck), operated by Dortmunder Stadtwerke (DSW21) at 20-minute intervals.
