On 29 September 2025, Siemens Mobility celebrated the groundbreaking ceremony for a new production facility for rail vehicle battery systems in Luhe-Wildenau (est of Nürnberg). On a state-of-the-art facility covering around 20,000 m2, up to 200 employees will manufacture battery systems for Siemens regional trains, locomotives, and external customers.
The project involves a total investment of around 35 million EUR, of which approximately 22 million EUR will be provided by Siemens Mobility. 2.7 million EUR comes as a subsidy from Bavarian funding programs. With this project, Siemens Mobility underscores its commitment to Germany as a production and innovation hub, makes an important contribution to the transport transition, and at the same time delivers on a promise of its “Made for Germany” initiative to drive growth and competitiveness in Germany.
Completion of the buildings is scheduled for spring 2027, with series production set to start in October 2027. A particular highlight of the event was the official handover of the funding notice by Bavarian Minister of Economic Affairs Hubert Aiwanger.
In Luhe-Wildenau, Siemens Mobility will in the future produce complete battery systems, including an innovative Battery Management System (BMS), developed together with Munich-based company Stercom. The BMS monitors and controls the battery, ensures safe operation, and maximizes efficiency and service life. The battery cells are sourced from external suppliers such as Toshiba, while system integration is carried out by Siemens Mobility.
