Mireo BEMUs for Remscheid - Düsseldorf services

A milestone for mobility transition in North Rhine-Westphalia (NRW): the new Mireo Smart Plus B trains for Regiobahn were officially presented on 17 July 2025 at Siemens Mobility's test center in Wegberg-Wildenrath. With the upcoming deployment of the three two-car battery Mireos on the RE 47 line between Remscheid-Lennep and Düsseldorf Hbf from summer 2026, Regiobahn is setting a strong example for climate-neutral mobility. 

The trains, ordered in December 2024, with a battery range of up to 120 km and a top speed of 140 km/h will replace the Integral DMUs on this important, 42 km long commuter route. With a total of 122 seats, spacious multi-purpose areas, and a separate first class with eight seats, additional passenger comfort is provided by WiFi, barrier-free access, and the particularly quiet operation of the trains. The trains have space for 12 bicycles. Another highlight is Siemens Mobility's high-frequency window solution, which significantly improves mobile phone reception on the train. Through collaboration with Smart Train Lease (STL) the procurement could be realized quickly and efficiently.

Alexandra Westerkamp, Chairwoman of the Supervisory Board at Regiobahn and Head of Department at VRR, said: “Since January, VRR has been the majority shareholder in Regiobahn. Thanks to this participation, we have succeeded in procuring new, locally emission-free vehicles for operating the RE 47 line from Remscheid via Solingen to Düsseldorf. For passengers, the transport between Bergisches Land and the state capital with the RE 47 is a great benefit. Travelers can travel directly to Düsseldorf without changing trains."

The Mireo Smart Plus B trains will use the existing infrastructure efficiently: the batteries can be charged both while running and while stationary - without additional charging facilities. For deployment on the Düssel-Wupper-Express (RE 47) from summer 2026, this means no structural adjustments, and no additional investments. Thanks to silicon carbide technology (SiC), the train impresses with particularly low energy consumption.

The trains will be maintained by Siemens Mobility as part of a full service contract, which guarantees almost 100 % availability in daily operations. In future, preventive and corrective maintenance will be carried out at Siemens Mobility's Dortmund Rail Service Centre. The manufacturer uses digital services from the Railigent X platform to continuously monitor the trains and examine them for possible faults so that they can be ordered to the workshop in Dortmund in good time for maintenance work. Thus, Siemens Mobility and Smart Train Lease provide their full range of services to Regiobahn.
