Siemens Mobility has begun production on hydrogen-powered trains set to operate on the Südostbayernbahn network in Germany by late 2026. The state of Bavaria has ordered three two-car Mireo Plus H trains, which will replace the current diesel trains running from the Mühldorf hub. This transition will significantly cut CO2 emissions and reduce both noise and exhaust gases in the region.
The new hydrogen trains will feature the European Train Control System (ETCS), ensuring high operational safety and efficiency. In addition to the train production, Siemens Mobility has secured a service contract for the hydrogen supply system. Deutsche Bahn, the parent company of the Südostbayernbahn, will also establish an electrolysis plant in Mühldorf, powered entirely by green electricity.
Andre Rodenbeck, CEO of Siemens Mobility’s Rolling Stock division, expressed pride in the project, stating, “We are proud to deliver Mireo Plus H hydrogen trains to Deutsche Bahn, helping enable emission-free travel in our home region. Our hydrogen trains use advanced technology, offering high energy efficiency, powerful performance, a long range, and quiet operation.”
The Mireo Plus H trains are built on Siemens’ established regional train platform, which offers electric, battery, and hydrogen-powered versions. The hydrogen-powered trains feature a roof-mounted fuel cell and lithium-ion batteries beneath the car floor, ensuring zero CO2 emissions during operation.
The trains have a combined drive power of 1.7 MW, allowing them to accelerate to 1.1 m/sec², reach a top speed of 140 km/h, and cover distances up to 1,200 km on a single hydrogen tank. Factors like route elevation and driving style will affect the range. The Mireo design incorporates a lightweight aluminum structure, which is not only energy-efficient but also environmentally friendly and aerodynamically optimized.
