Société du Grand Projet du Sud-Ouest

What Société du Grand Projet du Sud-Ouest does

Société du Grand Projet du Sud-Ouest (SGPSO) is a French public establishment (Établissement public), founded in 2022 and headquartered in Toulouse at 8 esplanade Compans Caffarelli, with a secondary office in Bordeaux. The organization was created to manage and deliver the Ligne Nouvelle du Sud-Ouest, a high-speed rail (LGV) project linking Toulouse, Bordeaux, and Dax in southwestern France, including the ancillary AFSB (Aménagements Ferroviaires au Sud de Bordeaux) and AFNT (Aménagements Ferroviaires au Nord de Toulouse) components. Construction began in February 2024 with a target service launch no later than 2032; once operational, the line will reduce travel time between Toulouse and Bordeaux from 2h10 to 1h05 and will create the first direct rail connection between Toulouse and Dax. Leadership comprises Guy Kauffmann as Directeur général and Alain Rousset, President of Région Nouvelle-Aquitaine, as President of SGPSO.

The core technology is civil and railway engineering at scale: new high-speed track, tunneling works, and integration with SNCF Réseau's national network. The project is designed to free capacity on existing lines for regional commuter services (trains du quotidien) and to support metropolitan RER development around Toulouse and Bordeaux. SGPSO does not operate commercial software products, APIs, or AI systems; its "product" is the physical infrastructure itself, handed to railway operators for service.

SGPSO's business model is public financing rather than commercial revenue. The project is funded by contributions from the French State, Régions Nouvelle-Aquitaine and Occitanie, and local collectivities across 13 departments. An additional 8 million euros has been mobilized via Préfectures for 2025-2026 to accompany local development projects linked to the line. End users are regional residents and travelers (commuter, leisure, business, healthcare, education, family), served indirectly once the line is operational via rail operators. Quantified outcomes include 10,000 construction jobs (4,000 direct, 4,000 indirect, 2,000 induced), 340,000 tonnes of CO2 avoided annually post-launch, and a target of carbon neutrality within 10 years of service commencement.

Partnerships

Three partnerships are on record, tiered core, major and minor.

• SNCF RéseaucoreStrategic or Co-development Partner · 1 February 2024SNCF Réseau is the national railway infrastructure manager responsible for implementing the works and maintaining the rail network. They estimate the additional costs of construction delays (€652-964 million for 12-18 months suspension).
• Bordeaux MétropolemajorStrategic or Co-development PartnerBordeaux Métropole, led by President Christine Bost, has evolved the AFSB project to optimize metropolitan RER functioning alongside the LGV. Actively supports the project for daily mobility decarbonization.
• Préfectures (Regional Administrative Offices)minorChannel Partner/ Reseller/ DistributorPrefectures of Haute-Garonne, Tarn-et-Garonne, Lot-et-Garonne, Gironde, and Landes serve as information points for development project financing related to the Ligne Nouvelle du Sud-Ouest (€8M available for 2025-2026).

Scale indicators7 records

Recent moves5 records

Expansion highlights5 records

Broad incumbents

• Eiffage Rail: Major French rail infrastructure constructor with deep involvement in LGV and conventional rail projects. Comparable as a delivery-side participant in French high-speed rail, though Eiffage is a contractor while SGPSO is the project owner.
• SNCF Réseau: French national rail infrastructure manager and SGPSO's core delivery partner for the LGV Sud-Ouest. Directly comparable as the operator of France's existing rail network and the entity that will integrate the new line; differs in being a national-scale incumbent versus SGPSO's project-specific scope.
• Bouygues Travaux Publics: French civil engineering contractor active in major rail and metro projects. Comparable as a delivery-side incumbent in French rail infrastructure construction, with similar exposure to public-project funding cycles and large-cap civil works.
• VINCI Construction / VINCI Highways: Global infrastructure group with significant French rail and motorway concessions (including LGV SEA via its subsidiaries). Comparable as a broad incumbent with rail infrastructure and concession capabilities, though VINCI operates at much larger scale and in multiple geographies.

Direct peers

• Lisea: Private concessionaire operating the LGV Sud Europe Atlantique (Paris–Bordeaux), the most directly comparable high-speed rail project to the Sud-Ouest line in terms of geography, technology, and passenger outcomes. Lisea is the operating concession while SGPSO is the public project owner — a closely aligned LGV use case.
• Société du Grand Paris: French public establishment managing the Grand Paris Express metro project. Closely comparable governance model: a dedicated public entity created to deliver a single, large-scale rail infrastructure program on a multi-year horizon, funded by national and regional authorities.
• Getlink (Eurotunnel): Operator of the Channel Tunnel rail concession, connecting France and the UK. Comparable as a cross-border rail infrastructure operator with a long-term concession model and exposure to European corridor economics relevant to SGPSO's Iberian/Mediterranean ambitions.

Regional players

• Rete Ferroviaria Italiana (RFI): Italian rail infrastructure manager owned by Ferrovie dello Stato. Comparable as a national rail infrastructure operator with responsibility for integrating Mediterranean corridor traffic that the Sud-Ouest line could feed; operates in Italy rather than France.
• Tisséo Collectivités: Public transport authority for the Toulouse metropolitan area. Comparable as a local public-entity counterpart coordinating commuter rail and metro services that will interface with the Sud-Ouest line's Toulouse terminus; operates in the same geography but at metropolitan rather than national scale.
• ADIF (Administrador de Infraestructuras Ferroviarias): Spanish national rail infrastructure manager, a direct counterpart to SNCF Réseau. Comparable as the upstream/downstream operator of cross-border corridors that the Sud-Ouest line will connect to; geographically adjacent and operationally linked but operating in Spain.
