For most domestic and intra-European train travel in 2026, arriving 15 to 20 minutes before your scheduled departure is usually sufficient. Unlike airports, European train stations generally do not have security checkpoints or check-in counters; you simply walk to your platform and board. However, there are significant exceptions: if you are taking the Eurostar (connecting the UK to mainland Europe), you should arrive 60 to 90 minutes early because of mandatory passport control and security screenings. For high-speed trains in Spain (AVE) or France (TGV), arriving 30 minutes early is wise, as there is often a quick baggage X-ray or a platform boarding cut-off. If you are unfamiliar with a massive station like Paris Nord or Berlin Hauptbahnhof, adding an extra 10 minutes to find your platform is a good idea. In 2026, many stations have shifted to "digital-first" signage, but the platforms are often not announced until 15 minutes before the train leaves. If you already have your digital ticket on your phone, you can head straight to the platform and be in your seat within minutes of arriving at the station.
