[2] The steep slope between Essen-Werden and Essen Stadtwald has always placed a high demand on the vehicles operating on it.

The Essen-Hügel station was built on a steep slope at the instigation of the Krupp family next to the Villa Hügel.

The stations of Essen Süd, Essen-Stadtwald, Essen-Hügel and Essen-Werden were modernised and harmonised as part of this work and 96 centimetre-high platforms were installed.

[3] Due to the effect of mining subsidence on a retaining wall north of the railway embankment between Essen-Stadtwald and Essen-Hügel, the line has been closed since 18 October 2017 and the trains of the S 6 from Dusseldorf terminate in Kettwig station.

During this period, buses are being operated between Kettwig and Essen Hauptbahnhof as rail replacement services.
