Roma–Napoli high-speed line is a high-speed railway connecting Rome and Naples in Italy. The line integrates with the national Italian high-speed rail network and links major hubs such as Roma Termini and Napoli Centrale, forming a core axis in Rete Ferroviaria Italiana’s strategy. It supports services operated by Trenitalia and Nuovo Trasporto Viaggiatori (NTV) under the brand Italo, improving travel times across the Metropolitan City of Rome Capital and the Metropolitan City of Naples.

Introduction

The corridor traverses the historical regions of Lazio (region) and Campania while connecting to national lines toward Milano Centrale, Bologna Centrale, and Salerno. Designed to complement the Direttissima (Florence–Rome) and the High-speed rail in Italy network, the route enhances links among stations like Roma Tiburtina, Napoli Afragola, and the Fiumicino Aeroporto axis. The project involved stakeholders such as ANAS, Ministero delle Infrastrutture e dei Trasporti, and the European Investment Bank.

Route and Infrastructure

The line extends roughly along the A1 corridor, featuring complex civil works including tunnels, viaducts and interchanges. Major engineering works involved the Liri Valley tunnels, the Caserta approaches, and the new Napoli Afragola railway station, designed by Zaha Hadid. Signalling systems deploy European Train Control System (ETCS) levels interoperable with legacy Sistema di Controllo della Marcia del Treno equipment. Key nodes include Roma Tiburtina, Cassino, Aversa, and Caserta railway station. The corridor integrates with freight corridors overseen by TEN-T and connects to the Port of Naples and Port of Civitavecchia via conventional links.

History and Development

Planning began amid debates involving Ferrovie dello Stato Italiane executives and Italian governments from the Silvio Berlusconi era through the Matteo Renzi administration. Early studies referenced the success of the Direttissima (Florence–Rome) and the Paris–Lyon high-speed line as models. Construction phases were executed by consortia including Salini Impregilo and international contractors such as Balfour Beatty partners. Funding combined national budgets, contributions from the European Union, and loans from the European Investment Bank. Key milestones included the opening of the southern section in the mid-2000s and completion of the full Rome–Naples axis by the late 2000s, enabling integration with Trenitalia’s Frecciarossa services and NTV’s Italo.

Services and Operations

Operators run mixed high-speed and conventional services, including Frecciarossa, Frecciargento, InterCity and private Italo trains. Timetables coordinate with long-distance services to Milano Centrale, Torino Porta Nuova, Venezia Santa Lucia, and Reggio Calabria Centrale. Ticketing systems interoperable with Trenitalia and third-party distributors enable connections to Fiumicino Airport. Operations comply with safety oversight from Agenzia Nazionale per la Sicurezza delle Ferrovie and scheduling coordination with regional authorities of Lazio and Campania.

Rolling Stock and Technology

Rolling stock includes ETR 1000, Pendolino derivatives, Alstom and Siemens high-speed trainsets, and legacy FS Class ETR 500 units adapted for the corridor. Trains use 25 kV AC on new stretches and 3 kV DC on legacy links, requiring multisystem capability similar to TGV and AVE units used in France and Spain. Onboard systems include ETCS Level 2/3 upgrades, predictive maintenance platforms developed with vendors like Hitachi Rail and Bombardier Transportation (now part of Alstom), and passenger amenities consistent with European high-speed standards.

Economic and Environmental Impact

The line accelerated economic integration between Rome and Naples, stimulating commuter flows and tourism to destinations like Pompeii, Amalfi Coast, and Vesuvius National Park. It influenced regional labor markets in Campania and Lazio and affected modal share versus the A1 motorway, domestic aviation on routes such as Rome–Naples air route, and short-haul bus operators. Environmental assessments addressed impacts on protected areas, water tables associated with works near the Garigliano River, and carbon reduction targets under European Green Deal frameworks. Noise abatement and biodiversity measures involved collaborations with ISPRA and regional environmental agencies.

Future Plans and Upgrades

Planned upgrades include full ETCS deployment, enhanced capacity through bi-directional signalling, and potential quadrupling of tracks in bottleneck sections near Napoli Centrale and Roma Tiburtina. Integration with the proposed Napoli–Bari high-speed rail and extended freight bypasses linking to the Adriatic Corridor and Mediterranean Corridor (TEN-T) is under study. Proposals from Rete Ferroviaria Italiana and EU-funded programmes aim to improve resilience to climate change and to deploy hydrogen or battery-hybrid shunting locomotives for terminal operations, involving manufacturers like Stadler Rail and CAF.
