TER hydrogène à quai

First hydrogen TERs arriving in stations in 2025

Four French regions have ordered 12 Régiolis H2 trains, and validation testing of a pre-series train is planned for 2024. We take a closer look at these innovative regional trains, set to enter commercial service in 2025.

12 Régiolis H2 trainsets on order

In March 2021, 4 French regions—Auvergne-Rhône-Alpes, Bourgogne-Franche-Comté, Grand Est and Occitanie—ordered dual-mode trainsets powered by electricity and hydrogen. Total cost for the project is €231 million.

    Régiolis H2 regional trains will replace diesel units

  • Diesel accounts for

Our commitment to the planet

The first hydrogen TERs are set to begin commercial operation from 2026, and the shift to hydrogen is just one part of our commitment to eco-friendly mobility. At SNCF, we’ve spent years working with manufacturers to develop cleaner TER trains.

Where to find the Régiolis H2

  • the Auvergne-Rhône-Alpes region will operate 3 trainsets on the Moulins–Clermont-Ferrand–Brioude line and the Lyon–Roanne–Clermont-Ferrand line.
  • the Burgundy-Franche-Comté will operate 3 trainsets on the Dijon–Laroche-Migennes–Auxerre–Avallon line and the Dijon–Laroche-Migennes–Auxerre–Corbigny line.
  • the Grand Est region will operate 3 trainsets on the Strasbourg–Haguenau–Niederbronn-les-Bains line.
  • the Occitanie region will operate 3 trainsets on the Toulouse–Montréjeau–Luchon line.
  • The H2 will have

    600 km

    of range in the hydrogen version

  • Voyageur à bord d'un TER

    It can carry

    220

    passengers

  • It can reach

    160 km/h

    running speed, the same speed as diesel TERs

How it works

In hydrogen trains, conventional diesel engines are replaced with fuel cells, batteries and hydrogen tanks. In the fuel cell on the H2 train’s roof, hydrogen from the tanks combines with oxygen in the air to produce electricity and power the train. And there’s only one waste product: water.
