Siemens secures long-term service contract for 61 battery-powered trains in Westphalia

• Siemens is supplying 61 climate-friendly Mireo Plus B trains, supplemented by a full-service contract for up to 30 years
• Long-term service contract ensures high availability and cost-effective operation in the Network North Westphalia

Rock Rail is relying on Siemens Mobility’s comprehensive Railigent X operations and maintenance concept in its work with the Westfalen-Lippe Local Transport Authority (NWL) to further develop regional rail transport in the Network North Westphalia (NNW). At the heart of the project is a full-service contract for 61 battery-electric Mireo Plus B trains, with a term of up to 30 years. As part of this long-term service package, Siemens Mobility will take full responsibility for the maintenance of the fleet, thereby ensuring almost 100 per cent availability. The aim is to achieve particularly reliable, efficient and sustainable operations on the Network North Westphalia, where the state-of-the-art battery-powered trains will enter service from December 2029.

Elmar Zeiler, CEO of Customer Service at Siemens Mobility:

“Long-term service contracts are a key factor in ensuring reliable and sustainable rail transport. This contract underscores precisely this importance: with our full-service approach, we are taking on complete maintenance of the Mireo Plus B fleet on the Network North Westphalia, thereby ensuring virtually uninterrupted availability over many years. In doing so, we are laying the foundations for efficient, cost-effective operations whilst also making an important contribution to the decarbonization of rail transport in Westphalia.”

Mike Kean, Chief Operating Officer:

“Reaching financial close on NWL marks another important milestone for Rock Rail and reflects the continued momentum of our business in Germany. The project demonstrates how innovative financing structures, specialist rolling stock expertise and long-term private capital can help deliver cleaner, more efficient transport solutions. We are proud to be working with Siemens Mobility, John Laing and NWL to bring this important fleet into service for passengers across the region.”

Christiane Auffermann, Managing Director of NWL:

“An attractive rail service needs more than just modern trains. For us, it is crucial that passengers on the Northern Westphalia network continue to benefit from a reliable and efficient service in the future. We are setting the course for this with our long-term service concept. At the same time, the planned investments in regional service and maintenance infrastructure send an important signal for the sustainable development of Westphalia-Lippe as a railway hub.”

Customer Services: the key to availability and cost-effectiveness

Under the long-term service contract, Siemens Mobility plays a central role throughout the entire lifecycle of the trains. The Customer Services division ensures that the trains can be operated continuously, reliably and cost-effectively. To this end, the company combines preventive, corrective and predictive maintenance, as well as digital analysis with solutions such as Railigent X, to enable condition-based maintenance even before the trains enter the workshop. This reduces downtime, optimises maintenance processes and sustainably lowers operating costs.

Sustainable technology for the mobility transition

The new Mireo Plus B trains are battery-powered multiple units (BEMUs) that draw their power from overhead lines and cover non-electrified sections of track with zero emissions. Intelligent energy management systems and energy recovery during braking ensure high efficiency and low operating costs. In addition to sustainable propulsion technology, the trains offer a high level of passenger comfort – including Wi-Fi, numerous charging points, accessible boarding and spacious multi-purpose areas.
