Introduction
In December 2023, Siemens Mobility handed over the first of 43 Mireo Plus H multiple-unit trains to Nahverkehrsverbund Rheinland (NVR). These trains are designated for use on the Rhine-Ruhr-Express (RRX) network in Germany.
Train Delivery and Testing
The handover of the initial train took place at Siemens Mobility’s Krefeld plant. The new trains will undergo extensive testing before entering passenger service. These tests include static and dynamic trials, as well as approval runs. The first train is expected to begin passenger service in the second quarter of 2024.
RRX Fleet and Operation
The entire RRX fleet comprises 82 trains. Of these, 43 are Mireo Plus H trains, while the remaining 39 are Desiro HC trains. The Desiro HC trains were supplied by Siemens Mobility and were put into operation between 2018 and 2020. The RRX project is a collaborative effort involving various transport authorities in the Rhine-Ruhr region, including NVR, Zweckverband Nahverkehr Westfalen-Lippe (NWL), and Verkehrsverbund Rhein-Ruhr (VRR). The operational management is handled by DB Regio AG. The trains will run on five RRX lines, connecting cities such as Cologne, Düsseldorf, Dortmund, and the surrounding areas.

The trains have a maximum speed of 160 km/h and a range of up to 1,000 kilometers. The total order for the Mireo Plus H fleet has a value of approximately €500 million. This project is supported by the Federal Ministry for Digital Affairs and Transport with funding of around €17 million.
Maintenance and Infrastructure
The maintenance of the Mireo Plus H trains will be carried out at the Rhine-Ruhr-Express depot in Dortmund. This facility will also serve as a center for hydrogen infrastructure. In addition to the Mireo Plus H trains, the Dortmund depot will also service the existing Desiro HC trains. The depot is designed to accommodate the entire RRX fleet.
