If your arrival doesn’t match the bus schedule, or if you miss the bus, you can get a train to Fratta Todina-Monte Castello from Termini Station in Rome. The trip will take longer - anywhere from three to four hours, but if you think of it as an opportunity to see the countryside, it’s not a bad trip.
First you must get to the Termini Station in Rome from the Airport.
There is a train station at Aeroporto Fiumicino, and you can take your airport luggage cart up the elevator to the second floor of the airport and go to the train station. The Leonardo Express costs €14 and is a direct train to Termini Station and leaves every 30 minutes.
Alternately, you take the Terravision bus to Termini Station for €4, with departures every 30 minutes. Get your boarding pass at Terravision Desk inside Terminal.
When you reach Termini, pay attention to your belongings! Termini station, unfortunately, is a notorious spot for pickpockets. The best thing is to remember is not to talk to beggars or strangers and to keep your personal space to a comfortable level. If you do feel harassed or are uncomfortable with someone, you can shout -Aiuto! (Ah-YOO-toh), which means HELP! You will find that Romans don't like thieves or scammers any more than anyone else and work hard to keep their city free of them. Most likely, you will be surprised how many civilians and police may run to help you and the individual bothering you will most likely run away.
You can buy a ticket for the next phase of your journey at the ticket office at Termini, or at one of the kiosks in the main area. You will want to get a one-way ticket to Fratta Todina-Monte Castello. Check the times and get the first available train. Since there is no phone at Montecastello station you should call us before you leave Termini with your expected arrival time.
En route to Monte Castello, you will change at Terni for a local (smaller, slower) train to Montecastello. Ask at the ticket window what time the train leaves. Walk through the underpass and up the stairs to Platform 5. If there's a wait for the train, you can go into the cafe and have a coffee or a drink. The ride from Terni to Todi, a beautiful trip through the country, takes 40 minutes. They don't announce the stops on the train; if you can't see the station signs from your window, ask the nice people around you to tell you when you reach Todi.
