TheFL2 (until 2012FR2) is aregional rail route forming part of theLazio regional railways network (Italian:ferrovie regionali del Lazio), which is operated byTrenitalia, and converges on the city ofRome, Italy.[1]
The route operates over the infrastructure of theRome–Sulmona–Pescara railway.[2] Within the territory of thecomune of Rome, it plays the role of acommuter railway. It is estimated that on average about 22,000 passengers travel on an FL2 train each day.
The electronicdestination boards at stations show only the designation "R" (Regional train).[2]
The FL2, aradial route, runs fromTivoli, via the Rome–Sulmona–Pescara railway, toRoma Tiburtina. The route heads initially in a northerly direction, loops around to the west and then the south, before finally turning again to the west, towards central Rome.[2]
The FL2, which was known as the FM2 until 2004 and as FR2 until 2012, was established in 1994, along with other suburban rail services, to encourage the use of rail transport in the Rome metropolitan area. Prior to 1994, regional trains along the Rome–Sulmona–Pescara railway linked Rome only with Abruzzo; following the FM2's introduction, FM2 services ran between Rome and Tivoli, stopping at all stations, with a frequency of one train every 60 minutes.
Since the establishment of the FR2, Tivoli–Rome passenger traffic has increased considerably, partly because this section serves the most populous part of the metropolitan area, and also partly because of vehicular congestion on theVia Tiburtina Valeria andA24. However, further actions by other entities were needed; the single track configuration of the line led to what were often long pauses for the crossing of trains, and this, combined with the proximity of the stations betweenLunghezza and Rome, made for a somewhat slow train ride.
Before work began on theRome–Naples high-speed railway, the urban sections of which would have flanked the tracks of the Rome–Sulmona–Pescara railway betweenRoma Prenestina andSalone, it was decided to convert this section fromdouble track toquadruple track as far as Lunghezza, and to build new stations, so as to establish a commuter service in all respects, and implement aclock-face schedule for it. Construction started on the high-speed railway in the late 1990s, and on the FR2 in the early 2000s. From 2002, due to work on the high-speed line, all trains on the FR2 were diverted toRoma Tiburtina until December 2005, when some trains from Pescara were again diverted, this time toRoma Termini. In the course of 2006, the quadruple track section between Roma Prenestina andLa Rustica Uir went into service, while in 2007 the quadrupling work was completed to Lunghezza.
The construction work on this section involved the renewal of the tracks, the creation of artificial tunnels close to built-up areas to avoid noise pollution, the radical restructuring of existing stations, and the inauguration of new stations (Serenissima,Palmiro Togliatti andLa Rustica Città).Tor Sapienza railway station was rebuilt and moved a few hundred metres (yards) closer to Rome than the original station, while at Roma Prenestina, FR2 trains were routed over the two secondary tracks, as the two main ones were reserved for high-speed services. Restructuring work at Lunghezza was completed in the course of 2008; FR2 trains now stop there a little further along with respect to the axis of thepassenger building, and the station entrance has been moved to face the new parking lot.
The stations on the FL2 are as follows:[3]
Therolling stock used on the FL2 route is a mixture ofTreno ad alta frequentazione electricmultiple units, andMDVE coaches hauled byE.464 classelectric locomotives.
The FL2 route is designated in Trenitalia official timetables as M75 Roma–Pescara FR2.
As of 2012[update], trains ran at hourly intervals between Tivoli and Lunghezza, and at half-hourly intervals between Lunghezza and Roma Tiburtina. Services are more frequent duringrush hour, with some trains to/from Roma Tiburtina being extended beyond Lunghezza and Tivoli, respectively, to link the capital with Bagni di Tivoli andMandela-Sambuci, respectively.[2]
