For travel on ItaliaRail (Trenitalia or Italo) in 2026, you should aim to arrive at the station 20 to 30 minutes before your scheduled departure. Unlike airports, there is no formal security "check-in" or "baggage drop" process for Italian trains, though major stations like Roma Termini or Milano Centrale now have security gates where you must show your ticket to access the platforms. Arriving 30 minutes early allows you to locate the "Partenze" (Departures) board to find your "Binario" (Platform) number, which is often not announced until 10–15 minutes before departure. If you have a paper ticket that needs validating (rare in 2026, as most are digital/e-tickets) or if you need to activate a Eurail Pass, you should add an extra 15 minutes to visit a self-service kiosk or ticket window. Note that doors on high-speed Frecciarossa trains typically close 2 minutes before departure, so being on the platform early is essential to avoid being left behind.
