DB Regio has ordered 29 Coradia Stream high-capacity electric double-deck multiple units from Alstom for use on the Frankfurt–Fulda–Bebra (RE50) and Frankfurt–Wächtersbach (RB51) lines.
These will increase transport capacity and reduce travel times in the Hesse region of Germany once they go into service in December 2025.

Thanks to the Coradia Stream HC’s fast acceleration, trains will be able to run at tighter interval. This will reduce the travel time between Frankfurt and Fulda by approximately eight minutes and will enable the RE50 to run to Bebra hourly during rush hour.
Following a call for tenders by Rhein-Main-Verkehrsverbund and Nordhessischer Verkehrsverbund, DB Regio will continue to operate the RE50 and RB51 lines beyond the planned timetable change on 14 December 2025.
Professor Knut Ringat, Managing Director of Rhein-Main-Verkehrsverbund, said:These new trains will enable us to offer over 1,080 seats between Frankfurt and Eastern Hesse at peak times, and 840 seats during normal hours compared to the previous 720.
In addition, the trains offer more comfort with power sockets at the seat and tables, as well as free wifi. With the combination of more space, more comfort and faster journeys, our passengers benefit quite considerably from the new Alstom vehicles.
The trains are expected to enter service in Kinzigtal from December 2025 and between Frankfurt, Central Hesse and Kassel even a year earlier.
Alstom will produce the trains for the Kinzig Valley Railway at its Salzgitter site. The project office with project and contract management, validation and commissioning, documentation and training will also be based in Germany.
This order follows similar contracts awarded to Alstom by LNVG and DB Regio last year for the Bremen/Lower Saxony express interchange and the Main-Weser subnetwork.
