The FL1 is a regional rail route forming part of the Lazio regional railways network, operated by Trenitalia, converges on the city of Rome, Italy. The route operates over the infrastructure of the Florence–Rome railway, the Pisa–Livorno–Rome railway and the Rome–Fiumicino railway. Within the territory of the comune of Rome, it plays the role of a commuter railway, it is estimated. The designation FR1 appears only in publicity material, in the official timetables, on signs at some stations; the electronic destination boards at stations show only the designation "R1". Orte ↔ Fiumicino AeroportoThe FL1, a cross-city route, runs from Orte, in the province of Viterbo, in a southerly direction over the Florence–Rome railway as far as Roma Tiburtina, it continues, via the Pisa–Livorno–Rome railway east and south of Rome's city centre, to Roma Trastevere. It takes the Rome–Fiumicino railway to Fiumicino Aeroporto, in the comune of Fiumicino southwest of the city centre; the first FL1 services between Monterotondo-Mentana and Fiumicino Aeroporto went into operation during 1994, bringing about an increased frequency of services on the lines through Rome.

The route included hourly trains between Orte and Monterotondo-Mentana. Until 2000, the FL1 route divided into two sections near Fiumicino: one train in every four branched off to Fiumicino Città, while the remaining services headed towards Fiumicino Aeroporto. Upon the introduction of the new timetable in 2000, the Fiumicino Città station was closed. On 7 December 2006, the new Fiera di Roma railway station was opened to the public, included in the FL1 route; the stations on the FL1 are as follows: Orte Gallese in Teverina Civita Castellana-Magliano Collevecchio-Poggio Sommavilla Stimigliano Gavignano Sabino Poggio Mirteto Fara Sabina-Montelibretti Piana Bella di Montelibretti Monterotondo-Mentana Settebagni Fidene Nuovo Salario Val D'Ala Roma Nomentana Roma Tiburtina Roma Tuscolana Roma Ostiense Roma Trastevere Villa Bonelli Magliana Muratella Ponte Galeria Fiera di Roma Parco Leonardo Fiumicino Aeroporto LE The FL1 route is designated in Trenitalia official timetables as M70 Orte–Fara Sabina–Fiumicino FR1.

As of 2012, FL1 services operated between Fara Fiumicino every 15 minutes. As some FL1 services originated or terminated in Fara Sabina or Poggio Mirteto, the FL1 trains ran between Fara Sabina and Poggio Mirteto every 30 minutes, linked Poggio Mirteto and Orte every 60 minutes.
