Regio Nord with class 628 diesel railcars with coupled sets (trains numbers up to 14141). The other service running on the line is operated by DB from Monday to Friday (train numbers from 14183). There were important connections in Minden to the RE 6 service to the Cologne/Bonn Airport and in Rotenburg to the RE 4 service to Hamburg, operated by Metronom. Operations There are no long-distance passenger services on this line. Local services The line has been served every two hours every day by the Porta-Express (RE 78: Nienburg–Bielefeld) since the 2017/18 timetable change. Previously, this only ran on this line on weekdays, while on the weekend, it ran on the Minden–Nienburg–Verden–Rotenburg (Wümme) route. It is operated with four-part Stadler FLIRT (class 429) diesel multiple units that are owned by eurobahn. The rolling stock that has been used since mid-January originally belonged to Westfalenbahn and still ran in its livery in March 2018. The first train runs to Bielefeld at 7:09 from Nienburg and in the opposite direction at 05:24 from Bielefeld. Both do not run on Sundays. The last trains depart at 21:09 from Nienburg and at 19:24 from Bielefeld; both timings are new since Eurobahn took over. The train from Minden at 8:01 starts, except on Sundays, in Rheda-Wiedenbrück at 7:04. In Nienburg, there is a direct connection to the Regional-Express service RE8 from/to Bremerhaven-Lehe via Bremen. There are some additional RE 78 services, that run only between Minden and Bielefeld. The average speed on the Minden–Nienburg section is 66 km/h and the maximum speed is 80 km/h. Freight Freight traffic runs on the line, including to the Heyden Power Station in Petershagen. Train can only cross on the otherwise single track only in Leese-Stolzenau and to the south of Nienburg. Operational features The line was still notable (as of 2013) in operational and railway technical terms because it is consistently equipped with mechanical safety technology, including semaphore signals. A number of abandoned stations are still recognisable on the basis of abandoned platform edges, characteristic entrance buildings with historical addresses and old freight loading facilities. The unrestricted level crossings are still only protected by the sounding of warning sirens.
