The S2IP consortium has been awarded a contract to the deliver civil project management works for the new rail tunnel link between Lyon and Turin.
The consortium includes French engineering and consulting group Systra, Setec, Italferr and Pini Swiss Engineers. Systra Sotecni, the Italian subsidiary of Systra, will also be part of the project team.
The contract has been awarded by Tunnel Euralpin Lyon-Turin (TELT), the Franco-Italian firm delivering the new railway line. TELT is owned by France up to 50% (Ministry of Economy and Finances) and Italy up to 50% (Ferrovie dello Stato italiane).
Under the contract, the consortium will be responsible for project managing two single-track parallel tunnels of 22.1km in length between Saint-Martin-La-Porte and La Praz in the French Alps.
The base tunnel includes two 57.5km tubes, of 45km is on the French side and 12km is on the Italian side with about 170 communication bypasses located each 333m.
The project will also include four intermediate accesses, five central ventilation systems and three underground security areas.
The cost of the cross-border section is estimated to be at around €8.6bn. Europe will finance up to 40%, Italy up to 35% and France up to 25% to deliver the international section of the Lyon – Turin link.
When opened in 2030, the tunnel will connect the international stations of Saint-Jean-de-Maurienne and Suse. The project is expected to enhance the connectivity between the two countries, as well as across Europe.
Upon operational, the project will minimise the travel time between Lyon and Turin from about four hours (3 hours and 43 minutes) to just under two hours (1 hour and 47 minutes). The new route is expected to be used by 4.5 million passengers every year.
Systra and Systra Sotecni have also involved in various studies and preparatory assignments, including project management of the Maddalena exploratory tunnel.
