Hydrogen multiple unit, 950 mm gauge for FDC
In June 2023, following a public tender, FdC (Ferrovie della Calabria) awarded Stadler a Framework Agreement for the supply of up to 15 hydrogen vehicles and signed the first contract for the supply of 6 HMUs. A five-year Full Service option is also foreseen.

Each HMU consists of two passenger cars and a central ‘Power Pack’ unit containing the fuel cells and hydrogen tanks. Each car is equipped with a motor bogie and a carrier bogie, both with reduced axle load. To enable completely safe operation, the HMUs are equipped with the SCMT automatic train protection system. Static converters and high-performance traction batteries are positioned above the motor bogies to ensure excellent adhesion and optimum tractive effort in all weather conditions. All major components are easily accessible for routine maintenance. Two doors per car and low-floor vestibules allow an easy access on board of all passengers including those with reduced mobility. Dedicated sliding steps allow as well a comfortable boarding from 250mm height platforms. One end-car is equipped with a universal PRM toilet. The air conditioning system features a set of air purifiers, aimed to increase the air quality, by effectively removing harmful particles and bacteria. The train also features areas for passengers with bikes and wheelchairs. Comfortable seats, wide panoramic windows, efficient energy-saving LED lighting, 220V and USB plugs at each seat, a modern Wi-Fi and an integrated passenger information system, complete the feature set-up to make the passenger travel pleasant and enjoyable.
