Trenitalia's flagship high-speed trains are the Frecciarossa 1000 (Red Arrow 1000), capable of 400 km/h in testing and operated commercially at 300 km/h on the Milan to Naples corridor. Milan to Rome takes 2 hours 55 minutes on the fastest Frecciarossa services. Milan to Naples takes approximately 4 hours 20 minutes. Rome to Naples is just 1 hour 10 minutes, one of the shortest high-speed intercity journeys in Europe. The slower Frecciargento uses tilting technology for routes off the high-speed lines, such as Rome to Reggio Calabria via the Adriatic coast, and Venice to Rome via Padova and Bologna.
Italo (Nuovo Trasporto Viaggiatori) began operations in 2012 as Italy's first fully private high-speed rail operator, competing directly with Trenitalia on the Milan to Naples corridor. Italo uses Alstom AGV trainsets capable of 360 km/h, operated commercially at 300 km/h. The company also runs services to Turin, Venice, Verona, Padova, Salerno, and Reggio Calabria using EVO Pendolino trainsets. Competition between Italo and Trenitalia has significantly reduced high-speed rail fares in Italy, with advance tickets available from as little as 9.90 euros.
Regional services in Italy are operated by Trenitalia's Regionale division and by regional concessionaries including Trenord (Lombardy), Trentino Trasporti (Trentino-Alto Adige), and BrennerBahn (Bolzano). Intercity trains serve medium-distance city pairs not on the high-speed network, running at 200 km/h on upgraded conventional lines. The Intercity Notte trains provide overnight sleeper services from Rome and Milan to Sicily (via Messina car-ferry) and the deep south of Calabria.
Trenitalia tickets are booked at trenitalia.com or through the Trenitalia app. Italo tickets at italotreno.it. The LeFreccce network has several fare types: Salotto (First/Executive suite carriage), Business (standard First Class), Premium (upgraded Standard), and Standard. Italy also operates the Carta Tutto Treno (Trenitalia's loyalty discount card) and the CartaFRECCIA rewards programme for frequent travellers. InterRail and Eurail passes are accepted on Trenitalia regional and Intercity services with free boarding, but require a fee for Frecciarossa seat reservations.
