How do we get from Rome airport to Tiburtina train station? Airport, Tiburtina, and Trenitalia give confusing info about three different trains. Does someone know the train we need and how to find it at the airport?
There are regional trains connecting Fiumicino airport with Roma Tiburtina, roughly one every 15 minutes. The station is clearly signed "Treni/Trains", though it is a bit of a walk on a covered walkway to get there, depending on which terminal you are at.
There are only very few train lines running from the airport. For Rome only two of significance, the Leonardo Express, which only goes to Termini, and the regional FM1. While a slower train, the FM1 is probably the best choice, it goes to a number of stops including Tiburtina, so no changing of trains needed.
You could also take the Leonardo Express to Termini; then, go downstairs at Termini to buy a Metro ticket. Take Line B to the third stop, Tiburtina.
Follow Paul's suggestion. Going through Termini you paying more than double the price plus the hassle of finding the subway. By the way, Paul means few as in two lines serving the airport as opposed to few trains. Trains run about every 30 minutes.
I've taken the train from FCO to Tiburtina a few times, and it's faster and less expensive than going via Termini. Ask the ticket seller for Tiburtina rather than Rome, and you'll get an 8 euro regional ticket that's good for the trip. You can also buy tickets at the kiosks. The FM1 trains use the left and right tracks at the FCO station while the Leonardo Express uses the center track. Check the signs to see which side departs next. Be sure to validate your ticket in the machines at the entrance to the platforms, as there are no validation machines along the platforms or on the train.
