Weser-Leine-Express
The Weser-Leine-Express (RE 70) is the name used in North Rhine-Westphalia (NRW) for a Regional-Express service that connects the east Westphalian regional centre of Bielefeld and Minden and the Lower Saxony regional centres of Hanover and Braunschweig. The NRW government found that there was sufficient state interest for it to support operations on the section in that state. The service alternates with the Ems-Leine-Express, which connects Rheine with Minden and Braunschweig. The border between North Rhine-Westphalia and Lower Saxony Between is crossed between Minden and Bückeburg.
