 The Duisburg–Mönchengladbach section was dropped in exchange for an extension from Duisburg to Düsseldorf in the timetable change in December 2002.Since then the "Rhein-Emscher-Express" has run entirely on the trunk line of the Cologne-Minden Railway Company, which was opened in 1846 and 1847.As of 15 December 2019, in connection with a change to the Rhein-Ruhr S-Bahn, a new Regionalbahn service line RB 32, the "Rhein-Emscher-Bahn", was added to the timetable, which runs parallel to the RE 3 between Dortmund and Duisburg, serving the stops between Gelsenkirchen and Oberhausen that were formally served by a branch of S-Bahn line S 2, including Essen Zollverein Nord.
