Rhine-Rhone high-speed link is a proposed and partially implemented high-speed rail corridor connecting the Rhine and Rhône corridors in central Europe via routes through Alsace, Baden-Württemberg, and the Swiss Plateau. The project interlinks major rail hubs such as Strasbourg, Mulhouse, Basel, and connects to wider networks including the Paris–Lyon high-speed line, LGV Est européenne, and the Mannheim–Stuttgart high-speed railway. It aims to enhance international passenger and freight mobility between Île-de-France, Grand Est, Baden-Württemberg, and Switzerland while interfacing with European Union transport initiatives.

Overview

The corridor is designed to provide high-speed services compatible with rolling stock from SNCF, Deutsche Bahn, SBB CFF FFS, and interoperable trainsets such as TGV, ICE 3, and Alstom AGV. Alignment options include dedicated high-speed tracks, upgraded mixed-traffic lines similar to the LGV Rhin-Rhône project, and cross-border links requiring coordination among Agence de l'Union européenne pour les chemins de fer, Établissement public, and national infrastructure managers like SNCF Réseau and DB Netz AG. Strategic objectives reference policy frameworks including the Trans-European Transport Network and bilateral agreements between France–Germany relations and Switzerland–European Union relations.

History and planning

Early proposals trace to studies by regional authorities in Alsace, Franche-Comté, and Baden-Württemberg during the late 20th century, influenced by precedent schemes such as the LGV Est européenne and the expansion of ICE network. Feasibility studies involved stakeholders including European Commission consultants, Réseau Ferré de France planners, and municipal governments of Strasbourg, Mulhouse, and Colmar. Political milestones involved debates in the French National Assembly, deliberations in the Bundestag, and cantonal consultations in Basel-Stadt. Funding models examined public-private partnerships with firms like Vinci and Siemens Mobility and grant mechanisms linked to Cohesion Fund allocations.

Route and infrastructure

Proposed alignments traverse the Upper Rhine Plain, linking junctions at Strasbourg-Ville station, Haguenau, Sélestat, and cross the Rhine near Kehl or via upgraded crossings at Breisach. Southbound options follow the historic Rhine Valley through Freiburg im Breisgau to Offenburg before angling to Mulhouse and Basel SBB railway station. Key infrastructure elements include new tunnels under the Vosges Mountains or expansions of the Haut-Rhin corridor, flyovers at Mülheim-style junctions, and gauge-compatible electrification interfaces for 25 kV and 15 kV systems. Intermodal nodes proposed at Strasbourg-Entzheim Airport, EuroAirport Basel-Mulhouse-Freiburg, and freight terminals like Mulhouse-Dornach enable connections to TGV inOui, DB Intercity-Express, and regional services such as TER Grand Est and S-Bahn Rhein-Ruhr-type operations.

Services and operations

Projected timetables envisage sub-two-hour links from Paris to Zurich via the corridor and enhanced regional frequencies between Colmar and Freiburg im Breisgau. Rolling stock interoperability requires compliance with European Train Control System and national safety certifications under agencies such as the Autorité de régulation des transports and Eisenbahn-Bundesamt. Operators under consideration include SNCF Voyageurs, DB Fernverkehr, and cross-border joint ventures modeled on Eurostar International Limited and Thalys International. Freight paths would mirror container flows between Port of Rotterdam hinterlands and Swiss logistics hubs, coordinated with terminals operated by SBB Cargo International.

Economic and regional impact

Analyses forecast shifts in modal share from air services like those using EuroAirport Basel-Mulhouse-Freiburg to rail, with economic spillovers for metropolitan areas such as Strasbourg Eurométropole, Freiburg Region, and the Metropolitan Basel. Regional development studies cite increased catchment areas benefiting universities like University of Strasbourg and research institutes such as Max Planck Society facilities in Baden-Württemberg. Investment discussions referenced instruments used in projects like the LGV Sud-Est and cited impacts on labor markets, tourism flows to Route des Vins d'Alsace, and logistics for firms including Siemens and Alstom.

Environmental and social considerations

Environmental appraisal processes invoked directives such as the European Union environmental impact assessment directive and required consultations with stakeholders including Natura 2000 site managers and cantonal authorities in Jura-adjacent areas. Conservation concerns highlighted habitats near the Rhine Forests and crossings affecting bird migration monitored by organizations like BirdLife International affiliates. Social assessments focused on community impacts in municipalities like Huningue and mitigation measures for noise and land take modeled after measures in the Gotthard Base Tunnel project.

Construction and timeline

Phased construction proposals mirror approaches used on the LGV Rhin-Rhône with initial upgrading of existing corridors, followed by new-build sections and interoperable electrification upgrades. Key milestones referenced include route selection procedures, tendering under procurement rules of the European Single Procurement Document, and staged commissioning akin to LGV Méditerranée openings. Timelines range from near-term upgrades deliverable within a decade to full-build scenarios extending over multiple decades, contingent on financing approvals from entities such as the European Investment Bank and national parliaments.
