Siemens Mobility has begun the production of hydrogen-powered trains for the Sudostbayernbahn network in Bavaria, Germany. The company received an order from the Bavarian state for three two-car Mireo Plus H trains to replace existing diesel trains in service from the network's Mühldorf hub. These trains will operate on 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 constructing an electrolysis plant in Muhldorf to produce hydrogen from green electricity. The hydrogen trains are expected to reduce carbon dioxide emissions and noise in the region, contributing to DB's climate neutrality goals. The Mireo Plus H trains feature advanced technology, including a roof-mounted fuel cell, lithium-ion batteries, and the ability to operate without CO2 emissions. With a drive power of 1.7MW, these trains can accelerate quickly and achieve a maximum speed of 140km/h. The trains can travel up to 1,200km on a single hydrogen tank and operate on non-electrified tracks, converting stored hydrogen into electrical energy. Siemens Mobility aims to deliver emission-free mobility through these hydrogen trains, highlighting their strong drive power, energy efficiency, operating range, and low noise levels. The company's commitment to sustainable transportation is further demonstrated by the construction of a new facility in the UK to enhance rail technology.
