Stazione Termini is Rome's main train terminal; the Tiburtina and Ostiense stations serve some long-distance trains, many commuter trains, and the FM1 line to Fiumicino Airport. Some trains for Pisa and Genoa leave Rome from, or pass through, the Trastevere Station. You can find English-speaking staff at the information office at Stazione Termini, or ask for information at travel agencies. Purchase tickets up to two months in advance at the main stations or at most travel agencies. Lines at station ticket windows may be very long: you can save time by using the electronic ticket machines, which have instructions in English, or by buying your ticket at a travel agency. You can reserve a seat up to one day in advance at a travel agency or up to an hour in advance at a train station. Tickets for train rides within a radius of 100 km (62 mi) of Rome can be purchased at tobacco shops and at some newsstands, as well as at ticket machines on the main concourse. All train tickets must be date-stamped before you board, at the machine near the track, or you may be fined.
