RB 69 and the RB 89, connecting Bielefeld and Paderborn hourly with Hamm and Munster. Its name refers to the Ems river and the Hellweg Börde (a fertile plain). Services start in Munster and run over the Münster–Hamm railway to Hamm. From there the RB 69 runs over the Hamm–Minden railway to Bielefeld and the RB 89 runs over the Hamm–Warburg railway to Warburg. Development The predecessors of the services were the DB Regio NRW-operated Westfalenbahn from Bielefeld/Paderborn via Hamm and Münster to Rheine. Because of the similarity of the name with the WestfalenBahn GmbH company, which was established in 2005, it was renamed the Ems-Börde-Bahn, referring to the Ems river and the county of Börde. Service The RB 89 service runs between Münster and Paderborn every half hour from Monday to Friday and every hour on weekends. The RB 69 runs between Münster and Bielefeld hourly each day, this service route connects with the RB 89 in Hamm, where trains on the two routes are coupled (or uncoupled if running in the opposite direction). The section of the train running as RB 89 continues from Hamm via Soest and Lippstadt to Paderborn, continuing every two hours to Warburg. Individual services in the morning and evening hours since December 2010 have operated to/from Kassel-Wilhelmshöhe. Especially on weekends there are additional services to/from Warburg, providing an hourly service during parts of the day on this section. Some trains running to/from Warburg do not stop on weekends at the stations of Borgeln, Dedinghausen, Ehringhausen and Scharmede. In Hamm there are also connections with Intercity-Express (ICE), Intercity (IC) and Regional-Express (RE) services on line RE 1 (NRW-Express, Aachen–Düsseldorf–Hamm). In Warburg it connects with the RE 17 (Sauerland-Express) to Kassel-Wilhelmshöhe. Once a day, in both directions, the RB 89 runs directly to Kassel-Wilhelmshöhe. The section of the train running as RB 69 continues from Hamm via Ahlen and Gutersloh to Bielefeld. This service together with the Rhein-Weser-Express (RE 6, Düsseldorf–Minden) produce a service every half hour. This service is complemented by the RB 67 (Der Warendorfer) service, which also runs between Münster and Bielefeld (operated until December 2013 by NordWestBahn, but now operated by Eurobahn), but uses the Warendorf Railway. Although the Warendorf line between Rheda-Wiedenbrück and Münster is shorter, Ems-Börde-Bahn services running via Hamm are about 10 minutes faster because of their higher average speed. The Ems-Börde-Bahn and Warendorfer operate to the same
