Calabria, Sardinia and Sicily are home to the world’s first narrow-gauge hydrogen-powered trains
The 21 trainsets manufactured by the Swiss group Stadler are destined for three operators: the Sardinian Regional Transport Authority (10 trains), the Calabrian Railways (9) and the Ferrovia Circumetnea (two) in Sicily
It is the world’s first narrow-gauge hydrogen train and will run on Italian tracks in three regions of southern Italy: Calabria, Sardinia and Sicily. These are lines currently served by old, polluting diesel trains. The Swiss manufacturer Stadler unveiled them at the Innotrans trade fair in Berlin, the world’s most important railway industry exhibition.
Manufactured at Stadler’s headquarters in Bussnang, in eastern Switzerland, the new trains will soon enable zero-emission rail operations. Stadler is currently building a series of 21 new trains for the Sardinian Regional Transport Company (Arst), the Calabrian Railways (FdC) and the Circumetnea Railway (Fce) in Sicily. The first train has been built for ARST in Sardinia, under a framework contract covering the design and development of a total of ten vehicles. Nine trains are also under production for FdC and two for FCE. In future, the trains will be deployed on regional and local services.
Over 2,100 tonnes less CO₂
The distinctive feature of the new trains is their environmentally sustainable propulsion system, based on fuel cells and hydrogen tanks installed in the central carriage, which operates in conjunction with the traction batteries. These batteries are recharged using the energy generated by the hydrogen. Thanks to this technology, the trains can run efficiently, environmentally friendly and without interruption on non-electrified lines. For example, compared with the use of diesel vehicles, ten hydrogen-powered trains will save up to 2,100 tonnes of CO₂ per year.
Compared with diesel trains, hydrogen-powered trains are considerably quieter, offering a further tangible benefit for local residents and passengers. Passengers will also be able to enjoy bright interiors and large panoramic windows. The low-floor access allows for easy boarding, even for people with reduced mobility.
