Yes, the United Kingdom is still a full member of the Interrail and Eurail community, and Brexit has not changed this. Interrail is governed by Eurail B.V., an organization made up of participating European railway companies, not the European Union. Therefore, you can use a Global Interrail Pass to travel on trains throughout England, Scotland, and Wales, including the high-speed Eurostar service connecting London to Paris, Brussels, and Amsterdam (though Eurostar requires a separate seat reservation fee of around €30). If you are a UK resident, you can buy an Interrail Pass to travel outside the UK, though your pass only allows for one "outbound" and one "inbound" journey within your home country. For non-European residents, the equivalent Eurail Pass also covers the UK. In 2026, the rail network in the UK remains a core part of the pass, providing access to scenic routes like the West Highland Line in Scotland and the coastal tracks of Cornwall.
