SBB, SNCF Voyageurs and Eurostar have signed a memorandum of understanding to explore launching direct train services between Switzerland and London in the 2030s. The agreement marks a new step in long-term plans to connect Swiss cities with the UK through direct international rail services.
The companies said studies indicate strong demand for direct rail links between Switzerland and London. Proposed journey times include around 6 hours between Zurich and London, 5 hours between Basel and London, and 5.5 hours between Geneva and London.
The memorandum follows a Cooperation Agreement signed in March between SBB and SNCF Voyageurs to strengthen cross-border rail partnerships and develop potential new international routes. The latest agreement also includes Eurostar, which has operated Channel Tunnel rail services between continental Europe and the UK for more than 30 years.
The three companies said they will now study possible timetables and operational concepts for the proposed services. The findings will help define the next steps and milestones required before a direct Switzerland to London connection can begin operating.
The companies said demand for international rail travel continues to grow, while London remains the top flight destination from Switzerland. They also said travellers increasingly want alternatives to short-haul flights.
A direct rail service between Switzerland and London would need to pass through France, making cooperation between the rail operators essential. SNCF Voyageurs already works closely with SBB on international services.
Several hurdles remain before direct trains can begin operating. The companies said work is still needed on border and entry procedures, infrastructure preparation, train path allocation, intergovernmental agreements and the availability of suitable rolling stock.
The partners said implementation would be feasible at the earliest sometime during the 2030s.
The latest development builds on previous studies and an earlier memorandum signed in London on 8 May 2025 by Swiss Federal Councillor Albert Rösti and UK Secretary of State for Transport Heidi Alexander. Under that agreement, SBB has continued studies on behalf of the Swiss Federal Office of Transport, while Eurostar and SNCF Voyageurs continue exploring new international rail connections.
