The FL4 (until 2012 FR4) is a regional rail route. It forms part of the network of the Lazio regional railways (Italian: ferrovie regionali del Lazio), which is operated by Trenitalia, and converges on the city of Rome, Italy.
The route operates over the infrastructure of the Rome–Cassino–Naples, Rome–Albano, Rome–Frascati and Rome–Velletri railways. Within the territory of the comune of Rome, it plays the role of a commuter railway. It is estimated that on average about 55,000 passengers travel on an FL4 train each day.
The designation FL4 appears only in publicity material (e.g. public transport maps), in the official timetables, and on signs at some stations. The electronic destination boards at stations on the FL4 route show only the designation "R" and the relevant train number.
The FL4, a radial route, runs from Roma Termini, on the southern perimeter of Rome's city centre, in a south easterly direction, via the Rome–Cassino–Naples railway, to Ciampino, and then fans out into three branches, to Frascati, Albano Laziale and Velletri, respectively.
The first of the three FL4 branches to see the light was the Rome–Frascati railway, opened on 7 July 1858, during the reign of Pius IX. At that time, the Roman terminus was located in Piazza di Porta Maggiore, and Frascati was more rural in nature.
Five years later, Roma Termini station was inaugurated, coinciding with the opening of the line to Velletri (continuing to Caserta and Naples). The line to Albano Laziale was opened in October 1889, on the formation of an earlier tramway from Tiburtina station.
