Il devait, à l’instar du CDG Express, débuter son exploitation pour les JO de Paris. Finalement, les usagers français auront attendu deux années supplémentaires.

En effet, le TGV M vient de franchir sa dernière étape avant sa mise en circulation à grande échelle. La livraison des rames à la SNCF débutera dès le début de l’été.



Il a obtenu l’autorisation de mise sur le marché délivrée par l’ERA, l’Agence de l’Union européenne pour les chemins de fer.

Cette étape cruciale permet de vérifier que le matériel répond aux “exigences de sécurité et d’interopérabilité”.

“La qualité du travail préparatoire et la coopération des parties prenantes ont contribué à la bonne progression de l’évaluation, marquant un des derniers jalons vers l’entrée en service du train
“, selon le communiqué de l’opérateur.

Désormais, la SNCF et Alstom, le constructeur, vont pouvoir accélérer la mise en place de ce train de nouvelle génération.


TGV M: Commercial operations slated to begin in September 2026

Thus, the delivery of the first two sets destined for operation is planned for June 2026. Four more will follow by the end of August and, in total, the carrier will have 13 sets by the end of 2026.



For train enthusiasts, you will still have to wait a few more weeks before hoping to boards this new rolling stock.

A phase of testing and adjustments in real-world conditions is essential before welcoming the first passengers.

SNCF Voyageurs and Alstom have chosen to strengthen the commissioning arrangements by planning a several-week pre-commercial run of the first sets on the national network.

This exceptional step will mobilize hundreds of teams from the two companies in order to check every detail of the onboard experience, support the adoption of the train by the operational teams and finalize the last adjustments before welcoming the first TGV INOUI travelers
