A new high-speed rail connection linking Belgium, France and Switzerland is set to be tested from summer 2027, as rail operators SNCB, SNCF Voyageurs and Swiss Federal Railways (SBB) join forces to extend the existing TGV INOUI service between Brussels and Strasbourg to Basel.
The trial service, scheduled to launch in July 2027, aims to strengthen rail connectivity between three of Europe's most important travel markets while offering passengers a more sustainable alternative to short-haul flights.
