the Sistema di Comando e Controllo ("command and control system"—SCC, an Italian version of centralized traffic control) of the Rete Ferroviaria Italiana, the subsidiary of the Ferrovie dello Stato group that is responsible for the management of the infrastructure, which supervises the rail traffic from the operations centre in Pisa for the section that runs from Civitavecchia to Sestri Levante (about 420 km) and from the operations centre of Genova Teglia for the section from Sestri Levante to the node of Genoa. Route Leaving Genova Brignole station, the railway runs through the eastern part of the city of Genoa, which it leaves at the former Sant'Ilario station. The landscape, characterised by the passage between villas, coast and cliffs, remains almost unchanged along the whole of the Golfo Paradiso as far as Camogli-San Fruttuoso. After crossing the promontory of Portofino, the line follows the Gulf of Tigullio, serving the tourist resorts from Santa Margherita Ligure to Riva Trigoso. This is the beginning of the Ligurian section, which is authorised for operations at higher speeds since the doubling of the line in recent times. The line then crosses the localities from Moneglia to Monterosso, which is at the beginning of the Cinque Terre section, noted for its long tunnels and sudden glimpses of the Ligurian Sea, picturesque villages and sheer cliffs. The landscape changes radically after La Spezia Centrale railway station and the line goes inland, reaching, after passing through junctions with a line to the port and the line to Parma, the plain of Luni, the last extension of Liguria. In Tuscany, the line runs through the provinces of Massa and Carrara and Lucca, remaining almost at the centre of the plain formed over the centuries between the chain of the Apuan Alps and the coast. In this section there were once many crossings and junctions with the extensive network of interurban tramways that included the Carrara-Marina di Carrara tramway, the Massa tramway, the so-called Tranvia litoranea di Viareggio (Viareggio coastal tramway) and the Viareggio-Camaiore tramway. After reaching Viareggio, the line passes through the junction with the line to Lucca and Florence, and reaches the Serchio river. It now enters the Pisan plain and arrives at Pisa San Rossore. This has an atypical layout for a passenger station as it is arranged in the triangle formed by the branch line of the railway to Lucca. During the construction of a building
