The Wuppertal-Vohwinkel-Essen Überruhr Railway is a 30 km (19 mi) long, continuous two-track electrified main line.

On 1 February 1872 the first part of the BME's Ruhr Valley Railway was opened from Düsseldorf-Oberbilk to Essen-Kupferdreh, and in 1874 another section of it from Essen-Überruhr to Hagen-Vorhalle (connecting with the Elberfeld–Dortmund line).

Both routes now no longer connect with the Prince William line, the sections from Essen-Kupferdreh to Essen-Werden and Essen-Überruhr via Altendorf (now Essen-Burgaltendorf) to Bochum-Dahlhausen are now closed and partially dismantled.

In the 1970s work began on developing the main lines in the central Ruhr area for the Rhine-Ruhr S-Bahn.

S-Bahn line S9 runs every 30 minutes from Wuppertal to Wuppertal-Vohwinkel, Velbert, Essen-Überruhr, Essen-Steele, Essen Hbf, Essen-Borbeck, Bottrop and Gladbeck.
