Until December 2016, the service was branded as Regionalbahn line Der Weseler from Duisburg to Wesel and operated towards Emmerich, Düsseldorf or Cologne during the peak in the peak direction. It was launched in 1998 with the introduction of the NRW-Takt. The line was operated with 425/426 class sets and sometimes with locomotive-hauled Silberling carriages by DB Regio NRW. Except for a test service that ran from December 2005 to June 2006 as Der Arnheimer between Emmerich and Arnhem, there had been no cross-border regional services between Amsterdam and Cologne since the cessation of the Eilzug service on the Oberhausen–Arnhem railway in the 1980s. Cross-border journeys have since then only been possible by bus or ICE International services. In order to again offer an attractive cross-border regional service, the Rhein-IJssel-Express was extended from Emmerich via Zevenaar to Arnhem on 6 April 2017, where it connects to the InterCity, regional sprinter services of the Nederlandse Spoorwegen, as well as to local trains operated by Breng and Arriva. Between Zevenaar and Arnhem, the, RE 19 complements the Dutch Arnhem–Doetinchem–Winterswijk and Arnhem–Doetinchem stopping trains. Another component of the tender of December 2016 was the operation of the non-electrified Wesel–Bocholt line. The Der Bocholter regional service was introduced on this line from Wesel to Bocholt. Assuming that the electrification of the railway line would be completed in December 2019, allowing portion working of the RE 19 line from Wesel, the line number RB 32 was re-assigned to the Rhein-Emscher-Bahn in advance of the 2019 timetable change. This meant that the Der Bocholter had to be assigned a new line number. Since then, the line has been designated as RE 19a, which was originally intended to be used for the portion-worked service, but as electrification of the line has not proceeded so far, the RE 19 cannot run on the line.
Rolling stock
Abellio procured nine Stadler Flirt 3 trainsets for use on the Rhein-IJssel-Express. These are three-system capable:
Diesel-powered Alstom Coradia LINT sets will be used for the RE 19a service until the line is electrified. A new workshop was built in Duisburg by Abellio to maintain the trainsets.
Route
The Regional-Express runs on the following railways:
Oberhausen–Arnhem railway from Oberhausen to Emmerich, over the whole length from 2017
Bocholt–Wesel railway, over the whole length from 2018.
''Hellweg-Express''
In the early days of the NRW clock-face timetable, there was another Regional-Express service that was designated as the RE 19. This service, called the Hellweg-Express, was operated by DB Regio NRW on the route from Dortmund via Unna to Warburg from 1998 to 2002. It was replaced at the timetable change on 15 December 2002 by the RB 59 and the RB 89.
