Introduction

Smart Train Lease GmbH has been contracted by Trans Regio Deutsche Regionalbahn GmbH to provide three Mireo Smart trains for the RB 32 line, with operations scheduled to commence on 14 December 2025. This eight-year maintenance contract and vehicle provision were signed on 19 August 2025, with the first train delivery planned for 1 October 2025.

Vehicle Provision and Contract Details

The vehicle provision contract was signed on 19 August 2025, with the first train delivery scheduled for 1 October 2025. Operations for the new RB 32 line are planned to start on 14 December 2025. The standardized vehicle concept allows for a rapid start of operations. The Mireo Smart trains will be provided by Smart Train Lease GmbH.

Operational and Service Expansion

The RB 32 line will operate electrically and non-stop from Ahrbrück via Remagen to Koblenz and further to Boppard. The new order marks the first expansion of an existing Mireo fleet via the Smart Train Lease model. Around 20 train drivers will be needed for the new services, with training provided by Trans Regio for the Remagen depot. The annual mileage of the existing service contract for Mireo and Desiro Mainline trains has also been increased.

Technical Specifications and Infrastructure

The Mireo Smart trains have a top speed of 160 km/h and 214 seats, including 12 in a separate first-class section. Generous multi-purpose areas provide space for up to 21 bicycles. Onboard internet (WLAN), numerous power outlets, and USB charging ports at the seats are available. The line runs on the Ahr Valley Railway, currently being rebuilt and set for electrification. The vehicles are fully connected to Railigent X, enabling condition-based maintenance, while the CORMAP solution supports planning and control of core maintenance processes. Siemens Mobility will ensure the timely supply of spare parts and provide expert manufacturer support through the eight-year service contract.

Strategic Partnerships and Regional Impact

This initiative highlights the strategic partnership between Siemens Mobility and Transdev. The new trains will be integrated into Trans Regio’s workshop in Koblenz. The RB 32 offers better connectivity to the Middle Rhine Valley. The expansion of services represents a key step in reconnecting and strengthening the Ahr Valley infrastructure after the 2021 flood disaster.
