On 6 November 2026, first TGV M operated by SNCF entered into commercial service in France. It is the first train to enter service based on Alstom’s Avelia Horizon very high-speed platform. On 22 May 2026, TGV M has obtained type authorisation from ERA as TGV 22000.
Avelia Horizon has been developed to meet the changing priorities of high-speed operators worldwide: increasing capacity, reducing energy consumption, optimising lifecycle costs and enhancing the passenger experience. Its architecture has been completely redesigned. From the power cars and passenger coaches to aerodynamics, traction, digital systems and maintenance, the train has been conceived as an integrated system. It incorporates more than 400 innovations for which patent applications have been filed.
Shorter power cars make room for an additional passenger coach within the same train length, allowing the new-generation TGV to offer up to 20 % more seating capacity than the previous generation with high level of comfort and accommodate up to 740 passengers. The train also consumes 20 % less energy than the previous generation, supported by improved aerodynamics, reduced weight and more efficient traction systems. At maximum capacity, this represents a 32 % reduction in energy consumption per passenger-kilometre.
Predictive maintenance systems, fewer components and improved accessibility have been designed to increase fleet availability and reduce maintenance costs by more than 30 % compared with the previous generation. Its scalable digital architecture also allows new technologies and passenger services to be integrated throughout its operating life.
