Siemens Mobility has begun the production of three hydrogen-powered trains, the Mireo Plus H, which are scheduled to commence operations on the Südostbayernbahn network in late 2026. These modern trains, ordered by the state of Bavaria, aim to replace diesel trains currently operating from the Mühldorf hub, leading to a significant reduction in CO2 emissions, noise, and exhaust gas in the region. The new trains will offer various passenger-centric features, including spaces for bicycles, high-frequency-permeable windows, and easy access due to their low-floor design. Equipped with the European Train Control System (ETCS), the Mireo Plus H ensures operational safety and efficiency. Siemens Mobility also secured a service contract for the trains' hydrogen supply system. Furthermore, the hydrogen trains will serve eight stations on a non-electrified route, leveraging an electrolysis plant powered by green electricity. These trains are recognized for their mature technology, energy efficiency, strong drive power, and low noise levels, contributing to emission-free mobility. Hydrogen trains are seen as a key component in achieving climate neutrality, offering environmental friendliness, operational flexibility, and noise reduction compared to traditional diesel trains.
