For most domestic and regional train travel in Europe, arriving 15 to 20 minutes before departure is generally sufficient. Unlike airports, there is no lengthy security or check-in process for standard trains. However, for high-speed international services like the Eurostar (connecting London to Paris or Brussels), you must arrive much earlier—typically 60 to 90 minutes—due to mandatory passport control and security screenings. Similarly, for major hubs like Paris Gare du Nord or Berlin Hauptbahnhof, giving yourself 30 minutes is wise to navigate the large platforms and find your specific carriage. In 2026, with the implementation of new biometric entry systems in the EU (EES), travelers are advised to check for specific updates on arrival times for cross-border routes. While the beauty of rail travel is its "hop-on" nature, arriving early ensures you have time to store your luggage, find your reserved seat, and avoid the stress of a last-minute dash through a crowded station.
