Siemens Mobility has started manufacturing hydrogen-powered trains for the Sudostbayernbahn network in Bavaria, Germany, with operations scheduled to commence in late 2026. The Bavarian state ordered three two-car Mireo Plus H trains to replace existing diesel trains in service from the network’s Mühldorf hub. These hydrogen trains will operate along a 32.3km non-electrified route connecting Muhldorf, Tubling, and Burghausen, serving eight stations. Siemens Mobility has also secured a service contract for the hydrogen supply system, with Deutsche Bahn planning to build an electrolysis plant in Muhldorf powered by green electricity. The new trains aim to reduce carbon dioxide emissions and noise in the region. The Mireo Plus H boasts a drive power of 1.7MW, a range of up to 1,200km on a single hydrogen tank, and can operate on non-electrified tracks using onboard fuel cells. Siemens Mobility CEO expressed pride in delivering emission-free mobility and emphasized the technology's efficiency, power, range, and noise levels. This initiative aligns with DB's goal of achieving climate neutrality and driving the transition to climate-friendly rail transport.
