Here are a few words and expressions to help you out when travelling by train - in treno - in Italy.
La stazione - Station
Il binario - Platform
L’orario - Timetable
La carrozza - Carriage
Il biglietto - Ticket
La biglietteria - Ticket office
Il viaggio - Trip / Journey
If a train is arriving, it is in arrivo or if it is leaving, it is in partenza. If it is late, it is in ritardo or if it is early, it is in anticipo. Once on the train, you may want to ask if a seat is free - È libero questo posto?
And an expression you hopefully won’t need when travelling by train in Italy is lo sciopero dei treni - train trike ... Buon viaggio!
