Lyon, Auvergne-Rhône-Alpes, France – Passengers at Lyon Part-Dieu station will soon experience a new era of high-speed rail travel with the official launch of SNCF’s TGV M trains, set to commence service on July 1, 2026. This highly anticipated deployment will first benefit the busy Paris-Lyon-Marseille line, promising a more modern and efficient journey for commuters and travelers alike.
A New Era of High-Speed Rail: TGV M Trains Set for 2026 Debut
After a period of anticipation and minor delays, the official in-service date for the new TGV M (Modulable) trains, manufactured by Alstom, has been confirmed. The first four trains are scheduled to begin operations in the summer of 2026, with the number of active trains increasing to eight by September and a total of thirteen by the end of 2026. This phased rollout will progressively introduce the advanced fleet to the French rail network, starting with a crucial intercity route.
Enhanced Design and Efficiency
The TGV M trains represent a significant leap forward in high-speed rail technology and design. Engineers at Alstom, in collaboration with SNCF, approached the project with a “blank slate,” resulting in a design that is not merely an update but a complete reimagining of the existing TGV fleet. These new trains boast a more aerodynamic profile, contributing to a 20% improvement in energy efficiency compared to their predecessors. This focus on sustainability aligns with broader efforts to reduce the environmental impact of transportation.
The modularity of the TGV M trains is a key feature, allowing for greater flexibility in configuration. Each train will consist of nine passenger cars, an increase from the current eight, boosting passenger capacity by 20% to a maximum of 740 seats. This adaptability extends to the ability to quickly convert first-class sections into second-class, catering to varying passenger demands. These trains will be utilized for both TGV Inoui and Ouigo services, offering a versatile solution for different travel preferences.
Significant Investment and Future Expansion
SNCF’s commitment to modernizing its fleet is evident in the substantial investment made in the TGV M program. An initial order of 115 trains (100 for France and 15 for Italy) was placed with Alstom in 2018, totaling 3.5 billion euros. Furthermore, on January 19, 2026, SNCF Voyageurs confirmed an additional purchase of 15 TGV M trains. This expansion aims to bolster services on international routes, particularly connections between France and Belgium, signifying a broader vision for enhanced cross-border travel.
The introduction of the TGV M trains is expected to address the growing demand for high-speed rail travel while improving the overall passenger experience. The increased capacity and modern amenities are designed to offer greater comfort and convenience, making rail travel an even more attractive option for millions of passengers annually.
Impact on Passengers and the Region
For residents and visitors of Lyon, the arrival of the TGV M trains at Part-Dieu station marks a significant upgrade to their travel options. The Paris-Lyon-Marseille axis is one of France’s busiest, and the enhanced capacity and efficiency of the new trains will be crucial in managing passenger flow and reducing travel times. This development reinforces Lyon’s position as a key transportation hub in France, connecting it more effectively with other major cities.
The TGV M project is a testament to ongoing innovation in the rail industry, with a focus on meeting contemporary demands for speed, comfort, and environmental responsibility. As the trains roll out in 2026, they are poised to transform the high-speed rail landscape in France and beyond.
