Siemens Mobility has started the construction of the hydrogen trains that will operate on the German Südostbayernbahn network starting 2026
Siemens Mobility is revolutionizing rail transport in Bavaria with the introduction of hydrogen-powered trains on the Südostbayernbahn network. This fleet of three 2-car Mireo Plus H trains, commissioned by the state, will replace diesel locomotives, significantly cutting CO₂ emissions and noise pollution. Company annouced today that it has started production of the hydrogen-powered trains that will begin operating in late 2026.
Set to begin operations in late 2026, the trains are designed for passenger convenience, featuring low-floor access, improved mobile phone reception, and dedicated space for bicycles. Equipped with the latest European Train Control System (ETCS), the Mireo Plus H ensures optimal safety and efficiency.
These hydrogen-powered trains will service the 32.3-kilometer, non-electrified rail route between Mühldorf, Tüßling, and Burghausen. A new electrolysis plant, powered by green electricity, will be constructed in Mühldorf to produce hydrogen fuel.
Andre Rodenbeck, CEO of Rolling Stock at Siemens Mobility, emphasized the train’s advanced technology, high energy efficiency, and quiet operation. Cornelia Würtz, Managing Director of DB RegioNetz Verkehrs GmbH, reaffirmed that hydrogen technology plays a key role in Deutsche Bahn’s climate neutrality goals.
The Mireo Plus H, based on Siemens Mobility’s proven regional train platform, features a roof-mounted fuel cell and lithium-ion batteries beneath the car floor. This system enables emission-free operation while delivering 1.7 MW of power, acceleration of up to 1.1 m/s², and speeds of up to 140 km/h. With a range of up to 1,200 kilometers per tank and a quick refueling process of approximately 15 minutes, the trains provide both efficiency and sustainability.
Hydrogen technology offers significant environmental benefits, producing only water vapor, reducing reliance on electrification infrastructure, and lowering noise levels compared to diesel trains. Siemens Mobility continues to innovate with digital solutions, ensuring sustainable, intelligent, and reliable transport systems for the future.
