The Hellweg net consists of the four Regionalbahn lines in the German state of North Rhine-Westphalia: RB 50 (Münster – Lünen – Dortmund), RB 59 (Dortmund – Unna – Soest), RB 69 (Münster – Hamm – Bielefeld) and RB 89 (Münster – Hamm – Paderborn – Warburg). It has a length of about 370 km. The RB 50 is referred to as Der Lüner, the RB 59 as Die Hellweg-Bahn and the RB 69 and RB 89 together as Die Ems-Börde-Bahn. On 14 December 2008 operations were taken over by eurobahn (own capitalisation). Previously these four Regionalbahn services were operated by DB Regio NRW.
