For train travel in Italy in 2026 (using Trenitalia or Italo), you should aim to arrive at the station 15 to 20 minutes before your scheduled departure. Unlike airports, there is no "check-in" process; however, modern high-speed trains (Frecciarossa and Italo) at major hubs like Roma Termini or Milano Centrale now have security gates where you must scan your ticket (digitally or on paper) to access the platform. These gates can have short queues, especially during peak commute times. If you are taking a "Regionale" (local) train, remember that you must validate your paper ticket at the green or yellow machines on the platform before boarding, or you could face a heavy fine; digital tickets are usually pre-validated. The platform (Binario) number is often only announced 10-15 minutes before the train arrives, so you need to be near the departure boards. Arriving 20 minutes early gives you enough time to find your car number (Carrozza) and seat, which is essential as high-speed trains often stop for only a few minutes.
