France’s new double-decker high-speed train made its inaugural run from Paris to Marseille on Friday, starting a gradual replacement of older trains on one of the country’s busiest rail corridors. The TGV M left Paris Gare de Lyon at 9:56 a.m. local time, [AFP](https://information.tv5monde.com/economie/plus-economique-et-ecologique-le-nouveau-tgv-dalstom-est-enfin-sur-les-rails-2844689?ref=theamericanquorum.com) reported. The train can run at up to 320 kilometers per hour, about 199 mph, matching France’s fastest existing TGVs. Its main gains are in capacity and onboard accessibility.

Friday’s departure marked the debut, while regular commercial runs are due to continue from Monday, Nov. 9, according to [SNCF Connect](https://www.sncf-connect.com/fr-ch/bons-plans/tgv-nouvelle-generation?ref=theamericanquorum.com). SNCF Voyageurs plans to deploy its first six trains on the Paris–Marseille corridor, starting with one round trip a day. Most travelers on the route will still ride older trains at first, even when booking under the same TGV INOUI brand.

## More seats without a faster trip

The TGV M that debuted Friday has 573 seats in its INOUI configuration, according to [L’Écho touristique](https://www.lechotouristique.com/transport/tgv-m-un-aller-retour-vers-nice-et-la-cote-d-azur-fin-novembre?ref=theamericanquorum.com), which covered the launch. The often cited figure of 740 seats applies to a higher density configuration for Ouigo, SNCF’s lower cost service. The higher figure therefore does not describe the service Marseille passengers are getting first.

SNCF and Alstom designed the train so that the number of coaches and the balance of first and second class seating can change. That gives SNCF a way to match the layout to different routes and seasons. The operator can also adjust space for luggage and bicycles. Shorter power cars free up room for an extra passenger coach within the same train length, according to [Alstom](https://www.alstom.com/press-releases-news/2026/11/alstom-reinforces-its-global-high-speed-rail-leadership-new-generation-tgv-enters-commercial-service?ref=theamericanquorum.com). The company puts the potential increase in seating at up to 20 percent over the previous generation. A capacity gain on a particular departure will depend on the layout of the new train and the one it replaces. These choices take place when a train is configured; they do not mean a particular departure will have extra seats or bike spaces available when demand spikes.

## What changes for passengers

In its [onboard guide](https://www.sncf-voyageurs.com/en/travel-with-us/new-generation-tgv/?ref=theamericanquorum.com), SNCF Voyageurs describes a wheelchair-accessible coach equipped with a lift and a device to bridge the gap between the platform and the train. The equipment is designed to let wheelchair users board independently. The carrier developed that part of the train with input from disability organizations, including APF France handicap. With just one initial round trip each day, access to that feature will depend on which departure a passenger takes.

The train also has eight bicycle spaces across three dedicated areas. Second class seats have adjustable headrests, individual power outlets and reading lights, while first class seats are five centimeters, or about two inches, wider. The bistro has a service area downstairs and a seating area above. Those features distinguish the new train from other INOUI services, even as they share the same route and booking system.

## A fleet renewal after years of delays

The line also has competition from Trenitalia’s Frecciarossa service, as AFP reported. For passengers comparing the two operators, the new equipment changes what SNCF offers on selected trips without shortening the route’s running time. The distinction is useful for travelers deciding whether to choose a particular departure for its onboard features or simply book the service that fits their schedule.

The debut came after repeated postponements from an early target of the 2024 Paris Olympics. SNCF announced in May that the European Union Agency for Railways had [authorized](https://www.sncf-voyageurs.com/fr/presse/le-tgvm-obtient-lautorisation-de-mise-sur-le-marche-delivree-par-lera-et-franchit-les-dernieres-etapes-avant-laccueil-des-premiers-voyageurs-tgv-inoui/?ref=theamericanquorum.com) the new train after reviewing safety and interoperability requirements. SNCF and Alstom then planned further running on the national network before carrying passengers. The May announcement had anticipated a September start, a milestone that also slipped.

SNCF reported nearly a million kilometers of testing in its May update. SNCF estimates the new design will use about 20 percent less energy and cost 30 percent less to maintain than earlier equipment. Those are projections from the operator and its manufacturing partner; regular trips will allow SNCF to measure performance in everyday service. The train also has a backup battery designed to let it reach the next station after an overhead power failure, AFP and L’Écho touristique reported. That feature addresses what happens when the power supply fails; it does not remove the risk of delays when a line is disrupted.

## Where the rollout goes next

SNCF Chief Executive Jean Castex said at the launch that the operator intends to extend the trains to the Côte d’Azur, followed by service toward the Alps. The first round trip to Nice is expected by the end of November, L’Écho touristique reported. The same outlet reported that Castex expects around 12 or 13 daily round trips on the southeastern network by January. That is a rollout target. Castex also told the outlet that the new train itself would not change fares. Travelers will still be comparing the prices offered on particular departures.

For now, travelers will see the greatest difference on the individual departures that use the new train. A wider effect on seat availability requires SNCF to put more of the fleet into regular use. The Paris–Marseille launch establishes a first route and a starting timetable; the pace of deliveries and the number of daily departures will determine how quickly the extra capacity reaches other passengers.
