French high-speed rail project TGV M set for commercial launch in 2026

The TGV M represents the first train to enter service on Alstom’s Avelia Horizon high-speed platform. This confirmation follows the project’s authorization for placement on the market, granted by the European Railway Agency in May 2026. SNCF Voyageurs had previously indicated that pre-commercial trials would precede the welcome of passengers.

The announcement comes after a postponement in September, when SNCF Voyageurs and Alstom delayed the launch to the autumn to continue adjustments related to passenger comfort and onboard services. The November 6th announcement signifies a transition from a circulation target to a confirmed operational entry.

While this marks a first deployment, not all INOUI trains will immediately feature the new TGV M. The renewal of the train fleet depends on deliveries, allocation of trains, and their gradual integration into service.

Alstom highlights the TGV M’s high capacity and reduced energy consumption, key objectives of the Avelia Horizon program. However, performance metrics such as punctuality, reliability, and passenger satisfaction remain to be assessed during real-world operation. Passengers seeking information about the specific train models for a journey should consult SNCF Voyageurs’ information during booking and prior to departure, as the TGV INOUI brand encompasses multiple generations of trains.

This launch initiates a new phase for SNCF and Alstom, focusing on service regularity, scaling up train operations, and delivering a positive passenger experience.
