Rome-Naples: upgrades toward completion

GCF is awarded the upgrade of the Formia - Villa Literno.

GCF's contract for Formia - Villa Literno as well

The technological upgrade of the Rome-Naples "direct line" via Formia continues. While work continues on the Latina-Formia GCF, winner of the recent tender under temporary grouping of companies, of about 19 million euros, is preparing the executive project to modernize and make more efficient the Formia - Villa Literno section as well.

Along the lines of the previous tender - awarded to GCF in association with Alstom - of which the new award is the natural continuation, the Formia - Villa Literno section will also be equipped with an evolved Central Computerized Multistation Apparatus (ACCM) capable of making circulation more efficient also on the additional 52-kilometre double-track section.

Particularly complex are the project works involving the construction of the IS facilities and yard works that are functional for the ACCM system that will control the stations and intermediate stops up to the Villa Literno station.

IS facilities

In particular, as far as IS facilities are concerned, the new ACCM and related BAcf-type spacing subsystem with RSC emulation will consist of a Multistation Central Post (PCM) to be installed in the premises of Roma Termini, 3 new PP/ACCs (n replacement of the current ACEIs) in the stations of Minturno-Scauri, Sessa Aurunca - Roccamonfina, Falciano - Mondragone - Carinola (the transformation of the ACEI in Formia into PP/ACC is included in the previous contract) and the construction of 21 Peripheral Track Posts (PPT) located on the line and 2 shelters located at the junctions of the Massico tunnel (5,380 mt).

In coherence with the intervention underway along the Latina-Formia section, also for the continuation segment towards Villa Literno, it is planned to replace the current electromechanical automatic block and equip it with the innovative RSC Emulated Static Automatic Block with 3 aspects (red, yellow, green) on the left track and with two aspects on the right track; powered by a single 1000 V backbone, it will be of the "distributed" type, i.e. with implementation located near the joints/signals.

An upgrade of particular impact as it will allow for constant monitoring and governing of convoy traffic and, if necessary, the automatic stopping of trains with the help of the Train Running Control System (SCMT).

Related works

Also of importance are the interventions of various kinds concomitant to and necessary for the realization of the new ACCM: these are alterations to the PRG (particularly for the Sessa Aurunca Station), railway and TE equipment, renovation of technological buildings, auxiliary civil works for station yard and line works (tunnels, piping, metal equipment, foundation blocks, basements, cabinets, walls, etc. ); IS-BA-SCMT technological systems, Light and Drive Power (LFM) facilities, telecommunication facilities with fibre optic cable backbones for connecting PBAs, RTB sentry boxes and shelters with PP/ACCs, industrial plant engineering, Safety, Security and mechanical facilities for managing the line's circulation.

Expected results

The duration of the works is estimated to be 1350 days, including the executive design phase and its approval. With this new intervention, the technological upgrade of the entire Rome-Naples "direct" railway (via Formia) will be completed, resulting in the renewal of all station and line equipment, as well as all power systems and new state-of-the-art transmission systems.

The intervention, once completed, will make the line once again at the forefront of technology in the same way as when it was built in the first decades of the last century, when the speed of 200Km/h was exceeded for the first time by a railway rolling stock on it.
