A study was carried out in September 1960[6] into the possible doubling of the line and the building of a branch from Porto station running directly to the airport.

[7] Direct Rome–Airport services were established (currently known as the Leonardo Express), initially operating from Roma Ostiense station.

[7] With the establishment of these services, the freight trains on the Livorno–Rome railway were diverted to run on the Roma Trastevere–Roma San Pietro–Maccarese route.

[4] After a few years of neglect, the railway infrastructure was removed and dismantled from 2007 as part of a redevelopment plan aimed at building a new district, including the new headquarters of the municipality of Fiumicino.

Turning left, the line passes under the A91; Fiera di Roma station is located a few metres past the flyover.
