line between Duisburg and Düsseldorf. In this four to six track section the Rhein-Weser-Express uses the S-Bahn tracks or the so-called local tracks where they exist, along with the Rhein-Haard-Express (RE 2) and the Rhein-Emscher-Express (RE 3), the Rhein-Hellweg-Express (RE 11) and the Rhein-IJssel-Express (RE 19). Only the NRW-Express (RE 1) and the Rhein-Express (RE 5) use the long-distance tracks. the Mönchengladbach–Düsseldorf railway between Düsseldorf and Neuss (together with other regional services), the Lower Left Rhine Railway between Neuss and Cologne (together with other regional and S-Bahn services and freight trains). the Hohenzollern Bridge between Cologne Hbf and Köln Messe/Deutz (together with all regional and long-distance trains), the Sieg Railway between Köln Messe/Deutz and the Cologne Airport Northwest junction (together with all regional and long-distance trains), the Cologne Airport loop to Cologne/Bonn Airport (together with all S-Bahn, regional and long-distance trains). Like the Rhein-Emscher-Express, the Rhein-Weser-Express runs for a large part of its route of the trunk line of the Cologne-Minden Railway Company (, CME). Between Dortmund and Duisburg, however, it uses the more developed and more centrally located route through the Ruhr built by the Bergisch-Märkische Railway Company (Bergisch-Märkische Eisenbahn-Gesellschaft, BME). Rail services Since the timetable change in December 2010, the Rhein-Weser-Express has run during the day at hourly intervals from Minden to Düsseldorf (extending to Cologne/Bonn Airport since December 2016), over the whole route between 0700 and 2200. Until the timetable change in December 2010 some services in the off-peak lengths turned around in Dortmund, Bielefeld or Hamm. Frequencies are increased by other services: the NRW-Express also runs between Hamm and Cologne and the Rhein-Hellweg-Express (RE 11) runs between Hamm and Düsseldorf, the Ems-Börde-Bahn (RB 69) runs between Bielefeld and Hamm, the Weser-Leine-Express (RE 70) and the Porta-Express (RE 78) run between Bielefeld and Minden. Large sections of the RE 6 proceeds parallel with S-Bahn lines and it has some of the character of a fast S-Bahn service and is perceived by passengers accordingly. Until 2016, the service was operated by DB Regio NRW, using push–pull trains of five double-deck carriages, mostly hauled by class 146.0 locomotives. Class 111 electric locomotives were regularly substituted on the route. The maximum speed of 160 km/h can be reached on long sections. The average speed is 84.5 km/h.
