In 2026, your right to switch trains depends on your region and ticket type. In the European Union and UK, if your train is delayed by more than 60 minutes, you generally have the legal right to "re-routing" at the earliest opportunity, which allows you to board the next available train to your destination without extra charge (often referred to as "Ticket Irregularity" rules). You should speak to a gate agent or conductor to have your ticket validated for the new service. In the USA (Amtrak), if a train is significantly delayed or canceled, you can usually be re-accommodated on the next available service, though you may need to visit a ticket window to "exchange" your reservation. Always check the "Passenger Charter" for your specific rail operator, as many modern apps now automatically update your digital ticket if a delay occurs.
