In the field of alternative propulsion systems, Stadler is presenting the world’s first hydrogen-powered train designed for narrow-gauge lines at InnoTrans 2026, in collaboration with three transport companies from southern Italy.
Built in Bussnang, the new trains will soon provide zero-emission rail services under the Italian sun. Stadler is currently producing a batch of 21 new HMUs for Sardinia’s Azienda Regionale Sarda Trasporti (ARST), Ferrovie della Calabria (FdC), and Ferrovia Circumetnea (FCE) in Sicily. The first train was built for ARST under a framework contract covering the design and development of a total of ten vehicles. Nine units for FdC and two for FCE are also in production. In the future, these trains will be used on regional and local services.
Each train has been specifically designed to meet the needs of different lines and operators, from the coastal routes of Sardinia and the mountain tunnels of Calabria to the steep gradients that characterise the Etna Nature Park in Sicily.
Maurizio Oberti, Stadler’s Sales & Marketing Director for the Italian market, says: “Thanks to close collaboration with the Ministry of Transport and the operators ARST, FdC, and FCE, Stadler has developed a modular solution capable of adapting to the diverse requirements of Italy’s narrow-gauge railway networks. All the trains are based on the same technological platform and combine a compact profile, lightweight mechanical structures, and an innovative hydrogen propulsion system. This integration ensures high standards of performance, innovation, reliability, and sustainability.”
Hydrogen produced using solar energy
The distinctive feature of the new trains is their environmentally sustainable propulsion system, based on fuel cells and hydrogen tanks installed in the central car (Power Pack), which operate in conjunction with traction batteries. These batteries are recharged using energy generated from hydrogen. Thanks to this technology, the trains can run efficiently, sustainably, and without interruption on non-electrified lines. Compared with diesel vehicles, ten hydrogen-powered trains will save up to 2,100 tonnes of CO₂ per year, equivalent to approximately 450 trips around the world by car.
The trains will be fuelled by green hydrogen produced entirely by using solar energy. ARST, FdC, and FCE are strongly committed to developing their power stations, which are currently under construction. Compared with diesel trains, hydrogen-powered trains are significantly quieter, providing a further tangible benefit for both local residents and passengers. Travellers will also enjoy bright interiors and large panoramic windows. Low-floor access ensures that passengers with reduced mobility can board the train with ease.
