South-west Germany is counting on Siemens: from 2020 onward, DB Regio AG will be operating its Rhine Valley rail network exclusively with new trains from Siemens. The German Railways order covers 15 Desiro HC and 24 Mireo trains in total, and goes hand in hand with a restructuring of the rail transport services in the Rhine Valley. There is a clear separation between a rapid train system for fast cross-regional services and a regional suburban rail system (S-Bahn) with stops at all stations. The Mireo will be deployed as a regional train (RB) service along the line section from Offenburg via Freiburg to Basel/Neuenburg (Switzerland) as well as in the Kaiserstuhl area on Sundays between Freiburg and Endingen/Breisach. The line section from Karlsruhe via Offenburg and Freiburg to Basel (Switzerland) will be operated with the Desiro HC as a regional express service.
