A multimodal hub serving the Lyon–Turin rail link
Commissioned in June 2022, the Saint-Jean-de-Maurienne multimodal interchange hub (PEM) ensures continuity of connections and access to the station during the rail interconnection works. It also prepares for the arrival of the Mont Cenis base tunnel and the creation of a future international station, facilitating links between trains, buses, cars and bicycles.
The works, carried out for TELT by SNCF Réseau with Eiffage Génie Civil and TSO, involve around 200 people and continue with the development of railway platforms, retaining structures, acoustic barriers and, ultimately, track laying and electrification.
Since February 2023, works have focused on railway platforms (1.5 million m³ of fill), 15 km of retaining walls, 10 km of noise barriers, the Arvan viaduct, the rehabilitation of surrounding roads and hydraulic structures. The next phase will include track installation and electrification, notably: 26 turnouts, 11 km of track, 19,000 sleepers and 52,000 tonnes of ballast.

Companies involved in the works
Rail interconnections are being delivered by SNCF Réseau on behalf of TELT, for a total value of approximately €800 million. Two civil engineering contracts have been awarded by SNCF Réseau: the first, worth €189.5 million over nine years, to Eiffage Génie Civil, and the second, worth €24 million over three years, to TSO SAS (starting in May 2025).

Temporary multimodal interchange hub
In July 2022, the new temporary hub replacing the former station was inaugurated to prepare the connection of the existing railway lines to the new base tunnel. To support passengers and keep stations operational during the works, TELT and SNCF Réseau built a temporary multimodal interchange hub, facilitating connections with other transport systems.
At the same time, a new road network was created to integrate the new station into its surroundings and improve links with neighbouring districts. Preparatory works were also carried out in the southern area of the Saint-Jean-de-Maurienne basin, in order to free up the space that will accommodate the new tracks near the base tunnel entrance.
