FL7 (Lazio regional railways)

The FL7 (until 2012 FR7) 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–Formia–Naples railway. Within the territory of the comune of Rome, it plays the role of a commuter railway. It is estimated that on average about 40,000 passengers travel on an FR7 train each day.

The designation FL7 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 FL7 route show only the designation "R" and the relevant train number.
