TELT Lyon Turin

What TELT Lyon Turin does

TELT (Tunnel Euralpin Lyon Turin) is a binational public infrastructure promoter established in 2015 by the French and Italian states, each holding 50% of the shareholding, to deliver and ultimately commission the cross-border section of the Lyon-Turin high-capacity rail line. The entity is headquartered in Chambéry, France (registered office) with operational headquarters in Turin, Italy, and coordinates a workforce of approximately 240 TELT professionals alongside 1,886 construction personnel as of 2025. TELT's core product is the Mont-Cenis Base Tunnel, a 57.5 km twin-tube railway tunnel connecting Saint-Jean-de-Maurienne in France to Susa/Bussoleno in Italy — positioned as the world's longest railway tunnel — part of the 270 km Lyon-Turin line within the EU TEN-T Mediterranean Corridor. Construction employs 7 tunnel boring machines across 6 active sites and 17 excavation fronts, with overall project completion at approximately 30.2% as of September 2026 and commissioning scheduled for the end of 2033.

TELT's business model is that of a public-sector construction manager rather than a commercial enterprise. The €11.1 billion certified project cost is funded approximately 40% by the European Union (Connecting Europe Facility), 35% by Italy, and 25% by France, with €700 million in EU grants allocated in 2024 across 134 supporting projects. TELT awards and supervises large construction contracts — including a €1 billion 2023 award to the UXT consortium (Itinera, Spie Batignolles, Ghella) — through a white-listed supplier base of approximately 600 qualified entities subject to anti-mafia regulation and oversight by three independent bodies. The organization holds ISO certifications across quality, environment, safety, anti-bribery, and road safety (9001, 14001, 45001, 37001, 39001), participates in the UN Global Compact, and has received the ITA Tunnelling Award.

TELT generates no commercial revenue and operates as a regulated monopoly concession holder under a binational intergovernmental framework. Its customer base is structurally limited to the two sovereign shareholders and the European Union as funders, with future rail freight and passenger operators positioned as downstream beneficiaries of the completed infrastructure rather than customers of TELT directly. Go-to-market is therefore governmental rather than commercial, and pricing/revenue mechanics are replaced by sovereign capital contributions tied to construction milestones.

Direct peers

• TP Ferro: Concessionaire operating the Perthus Tunnel on the Figueres–Perpignan high-speed line linking Spain and France — directly comparable as a cross-border rail tunnel operator in the Mediterranean Corridor ecosystem.
• AlpTransit Gotthard AG: Swiss public promoter that delivered the 57 km Gotthard Base Tunnel (world's longest railway tunnel until TELT's completion) — directly comparable as an Alpine rail base tunnel promoter with similar construction, geological and operational profile.
• Brenner Basistunnel BBT SE: Public promoter building the 55 km Brenner Base Tunnel between Austria and Italy under the Alps — structurally identical mission to TELT (Alpine cross-border rail base tunnel with EU co-financing and multi-sovereign governance).
• Femern A/S: Danish state-owned promoter building the 18 km Fehmarn Belt Fixed Link immersed rail/road tunnel between Denmark and Germany — comparable as a large cross-border European rail infrastructure project under EU TEN-T with sovereign-backed financing.
• Getlink: Operates the Channel Tunnel between France and the UK under a long-duration cross-border rail concession — directly comparable to TELT's planned role as a binational rail tunnel infrastructure operator with line‑haul freight and passenger services.

Broad incumbents

• Adif: Spanish national rail infrastructure manager and administrator of the Iberian side of the TEN-T Mediterranean Corridor — a broad incumbent rail infrastructure manager within TELT's broader corridor ecosystem.
• RFI - Rete Ferroviaria Italiana: Italian national rail infrastructure manager that will integrate TELT's cross-border section with the Italian network — directly comparable as the institutional counterpart in Italy and a broader national rail infrastructure operator.
• SNCF Réseau: French national rail infrastructure manager that will integrate TELT's cross-border section with the French network — a broad incumbent rail infrastructure manager serving as TELT's institutional counterpart on the French side.

Others

• Herrenknecht: German manufacturer of the custom dual-mode tunnel boring machines used on the Lyon-Turin project — a key technology supplier and ecosystem partner (not a direct peer), but central to TELT's excavation capability.
• Webuild: Italian major infrastructure contractor historically involved in Alpine rail tunnelling and adjacent works on the Lyon-Turin corridor — an overlapping contractor/ecosystem participant rather than a direct competitor to TELT's public-promoter role.
