The Lower Ruhr Valley Railway (German: Untere Ruhrtalbahn) is a former railway in the German state of North Rhine-Westphalia. It was opened on 24 January 1876 by the Bergisch-Märkische Railway Company (Bergisch-Märkische Eisenbahn-Gesellschaft, BME) along the Ruhr to the southwest of the city of Mülheim an der Ruhr and connects Mülheim-Styrum on the Witten/Dortmund–Oberhausen/Duisburg railway and Essen-Kettwig on the Ruhr Valley Railway.
