On 22 May 2026, TGV M has obtained type authorisation from ERA as Type TGV 22000. SNCF Voyageurs and Alstom are delighted that the approval testing programme, which has been underway since 2023, achieving nearly 1 million km of runs, has enabled them, thanks to the intense efforts of their teams, to submit a complete application in December 2025. Over 1,000 documents made up the type-certification dossier (test reports, expert opinions, drawings, etc.).
The production schedule drawn up jointly by SNCF Voyageurs and Alstom provides for the delivery of first Class 22000 (Avelia Horizon) trains intended for service from the start of summer, with a gradual ramp-up in the second half of 2026: delivery of the first two 1.5 kV DC/25 kV 50 Hz units from June, rising to six TGV Ms by the end of August, and 13 trains by the end of 2026.
SNCF Voyageurs and Alstom have decided to strengthen the commissioning process by scheduling several weeks of pre-commercial running of the first trains on the French network. This phase will involve hundreds of team members from both companies to verify every detail of the on-board experience, support the operational teams in familiarising themselves with the train, and finalise all last adjustments before welcoming the first passengers.
The passenger service of this new TGV INOUI units will start in early September. The pre-commercial trial phase prior to commercial service will enable the first six TGV INOUI trainsets to be integrated into the timeline during a suitable operational window. In total 130 trains were ordered by SNCF Voyageurs. In July 2018, SNCF placed an order for 100 dual-voltage TGV M units. In August 2022, SNCF ordered 15 quadruple-voltage Class 42000 TGV Ms for international services. In January 2026, SNCF exercised a further option for 15 quadruple-voltage units. Another 30 trains (plus 20 optional ones) were ordered by SNCF subsidiary Eurostar.
Alstom states that the TGV Ms will have 30 % lower maintenance costs compared to TGV Duplexes, as well as 20 % energy savings thanks to its more aerodynamic shape. 90 drivers were involved in the design of the new driver’s cab. Seats were tested by 125 customers of different body types. Passenger seats are 90 % recyclable thanks to their materials.
