# Sleek Emissions-Free Trains This Hydrogen Train Was Developed for Narrow-Gauge Italian Tracks By Michael Hemsworth | Published 2026-06-30 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/hydrogen-train References: [newatlas](https://newatlas.com/transport/world-first-narrow-gauge-hydrogen-train-stadler-arst/) & [stadlerrail](https://www.stadlerrail.com/en/media/media-releases/world-s-first-narrow-gauge-hydrogen-train-unveiled)  This hydrogen train has been developed through a partnership between Stadler and ARST as a way to help contribute towards the decarbonization of the railway lines in areas with infrastructure constraints. The train takes aim at the narrow-gauge tracks found in Sardinia, Calabria and Sicily in Italy where existing [hydrogen-powered locomotives](https://www.trendhunter.com/trends/tacoma-h2overlander-concept) don't work due to space constraints. The train is equipped with a propulsion system that relies entirely on [hydrogen fuel cells](https://www.trendhunter.com/trends/hydrogen-cartridges) and keeps them concentrated in the Power Pack car as a way to maximize accessibility and comfort as well as efficiency. The hydrogen train comes as part of a broader effort supported by the [Italian government](https://www.trendhunter.com/trends/beverage-can-recycling) to decarbonize narrow-gauge rail networks throughout Southern Italy. The entire fleet will need to undergo certification by Italy's national rail safety agency before passenger service begins.
