From 06.01.20 to approximately 25.10.2020 the railway line Düren - Davensberg (RB 50) is closed due to construction work. Therefore all students with the NRW Semesterticket are allowed to use the direct IC/ICE connections between Münster - Dortmund (only direct connections, not allowed to use trains via e.g. Hamm or Recklinghausen).
The validity of this information was given by the local traffic enterprise NWL. In case of train personnel requesting the validity you can refer them to page 6 of this flyer ( https://www.nwl-info.de/fileadmin/NWL/Downloads/Informationen_fuer_Fahrgaeste/ERB_RB50_Dammsanierung_Broschuere.pdf?fbclid=IwAR0-cqSBeav7m208T4EFkFvTL_HKuU3oQ9Ox_-Bjni-f-Z_Kt-SLfoVTNSo ) by the NWL and Eurobahn.
