The first Alstom Avelia Horizon trainsets — now branded TGV Nouvelle Génération by national operator SNCF Voyageurs — began carrying passengers on November 6. Jérémie Anne reports from onboard the first service from Paris to Marseille. The passenger launch of the 320 km/h trainsets took place in the presence of Minister for Transport Philippe Tabarot, SNCF Group Chairman & CEO Jean Castex and Alstom Chairman & CEO Martin Sion. An initial six trainsets have entered revenue service, operating between Paris Lyon and Marseille St-Charles. A Paris – Nice return service will be added at the end of November, and services to the Alps are to follow in 2027. TGV of the future Alstom said the Avelia Horizon represents the most significant evolution in its very high speed train architecture since the TGV Duplex which entered service in 1996. The TGV of the future project to design a fifth generation of French high speed train was launched in 2016, when Alstom entered into an innovation partnership with SNCF Voyageurs. Alstom’s focus was offering higher capacity within existing train length and width, along with lower energy consumption, optimised maintenance costs and the flexibility to tailor the technical configuration, capacity, interior layout and passenger facilities to the operational, regulatory and market requirements of different customers. The project was developed by SNCF as TGV M, with the operator saying the M stood for the French words for modernity, mobility, modularity, management, better and partnership. It subsequently became TGV Inoui, and now TGV Nouvelle Génération. Speaking at the launch, David Goérès, TGV M project manager at SNCF Voyageurs, said 2 000 staff from Alstom and SNCF Voyageurs are working on the project, with 11 Alstom industrial sites in France involved in manufacturing, including Belfort and La Rochelle. Nearly 400 innovations in a 10-year project Avelia Horizon features nearly 400 innovations for which patent applications have been filed. The reduced weight, improved aerodynamics and more efficient traction systems have contributed to an overall 20% reduction in energy consumption, and a 32% reduction in energy consumption per passenger-km at maximum capacity. Energy storage units behind the power cars can keep safety and passenger comfort systems running if the power supply is lost in an emergency, and provide enough traction power to reach a station to avoid leaving passengers stranded in the countryside. SNCF Voyageurs is spending €300m to adapt its maintenance facilities for the new fleet, in particular the Technicentre Sud-Est Européen where the first trainsets are maintained. The trainsets for French domestic services have nine articulated aluminium double-deck coaches and two power cars equipped for 1.5 kV DC and 25 kV 50 Hz electrification systems. The power cars are shorter than those of the Euroduplex, creating room for an additional passenger coach within the same train length, and the cab has been completely redesigned, with a European driver’s desk and a single combined traction/brake controller. The trainsets are fitted with Hitachi dual ERTMS/TVM signalling systems as well as KVB. The trainsets are 202 m long with 573 seats in first and standard classes. A high-density configuration proposed for Ouigo services could carry 740 passengers. Every seat has USB and mains power sockets, an individual reading light and wi-fi. There are passenger information screens on the doors and in each saloon. Luggage areas and toilets have been redesigned, and there are cycle spaces. Coach 3 has a mobile platform to enable wheelchair users to reach the lower deck independently. Predictive maintenance systems, a reduction in the number of components and improved access aim to increase fleet availability and reduce maintenance costs by more than 30% compared with the previous generation of high speed train, with a scalable digital architecture designed to allow new technologies to be integrated throughout its operating life. SNCF Voyageurs orders In 2018 SNCF Voyageurs placed a €2.7bn order for an initial 100 trainsets for use on French domestic services from Paris Lyon. Entry into services had originally been envisaged for 2023-24, ahead of the 2024 Olympic Games. In 2022 a €590m order was placed for a further 15 sets for the Paris – Milano route to Italy and planned Italian domestic services on the Torino – Napoli and Torino – Venezia routes, with entry into service expected in 2028. A €1.4bn order for a further 30 trainsets for use by Eurostar was placed in October 2025, and these sets, branded Celestia, are due to enter service in May 2031. A further 15 quad-voltage trainsets were ordered by SNCF Voyageurs in January 2026 for France – Brussels services, with entry into service expected in 2029. All 160 trainsets are being financed from SNCF Voyageurs’ own funds, representing an investment of €4bn. Similar trainsets have been ordered by Morocco’s national railway ONCF, and 12 have been ordered by French open access start-up Velvet. By relying on a train design already selected by SNCF, Proxima hopes to avoid the testing and certification complexity of bespoke rolling stock programmes. ‘The entry into service of the new-generation TGV is a new demonstration of Alstom’s global leadership in high speed rail’, Alstom CEO Martin Sion said . ‘As the first train to enter service based on our Avelia Horizon platform, it builds on 45 years of experience and operational knowledge gained around the world. It is also the result of many years of close co-operation with SNCF and of the contribution of thousands of people across Alstom, our partners and our wider industrial ecosystem.’ See also SNCF confirms TGV of the Future order Rolling stock: Olympic deadline governs TGV M rollout SNCF unveils TGV-M livery Brakes and HVAC ordered for next-generation TGV First TGV M unveiled by Alstom and SNCF
