In 2026, the United Kingdom remains a core member of the Interrail network, as the program is managed by Eurail B.V. and the International Union of Railways (UIC), which are separate from the European Union. Despite Brexit, the UK’s primary rail operator, National Rail, continues to participate fully. This means that if you are a resident of a European country (including the UK itself), you can use an Interrail Pass to travel across Great Britain. Conversely, if you are a non-European resident, you would use a Eurail Pass to visit the UK. For Interrail Global Pass holders, the UK is one of the 33 covered countries, and the pass also provides access to the Eurostar high-speed service connecting London to Paris, Brussels, and Amsterdam (though a seat reservation fee is required). The UK’s status as a "European country" for rail travel remains unchanged, ensuring seamless rail connectivity for travelers moving between the British Isles and mainland Europe.
