FS Class E.403

Trenitalia is the primary train operator in Italy. A subsidiary of Ferrovie dello Stato Italiane, itself owned by the Italian government, the company was established in 2000 following a European Union directive on the deregulation of rail transport.

Rete Ferroviaria Italiana (RFI) is the Italian railway infrastructure manager, subsidiary of Ferrovie dello Stato (FS), a state-owned holding company. RFI is the owner of Italy's railway network, it provides signalling, maintenance and other services for the railway network. It also operates train ferries between the Italian Peninsula and Sicily. RFI's origins can be traced back to a series of railway sector reforms enacted by the Italian government during the late 1980s and 1990s. The agency was founded on 1 July 2001 in accordance with a European directive on rail transport that mandated the separation of the infrastructure operator and the service operators. Prior to RFI's creation, the Italian rail network was managed directly by FS. The agency has been periodically accused to a failure to be impartial, including allegations of favouring sibling company Trenitalia over independent operations; the company has been fined in the past for anti-trust breaches. Since its creation, revenue abstraction from access charges have steadily increased, primarily due to the expansion of Italy's high-speed rail network, even as access charges have been decreased.

The Italian railway system is one of the most important parts of the infrastructure of Italy, with a total length of 24,227 km (15,054 mi) of which active lines are 16,723 km. The network has recently grown with the construction of the new high-speed rail network. Italy is a member of the International Union of Railways (UIC). The UIC Country Code for Italy is 83.

The E.412 class is a batch of multi-role electric locomotives built for the mountain lines, particularly for the northern Italian lines of the Brenner pass. They are known as Brenner or Brennerlok locomotives. 28 units from both the groups have been acquired by Trenitalia, as part of a process of simplifying rail operation between Italy, Switzerland, Austria and Germany. The locomotives are qualified for running on French rails, too, making the E.412s potentially fit for service on most European lines except the high-speed rail lines.

The FS E.636 is a class of Italian articulated electric locomotives. They were introduced in the course of the 1940s until the 1960s, and have been decommissioned since 2006. They have been one of the most numerous Italian locomotive group, and have been widely employed during their long career, hauling every type of train, ranging from freight to long range passenger services. Their introduction also saw the employment of some revolutionary design concepts, such as the articulated carbody and the three bogies scheme.

The Italian railway system is one of the most important parts of the infrastructure of Italy, with a total length of 24,227 km (15,054 mi) as of 2011.

High-speed rail in Italy consists of two lines connecting most of the country's major cities. The first line connects Turin to Salerno via Milan, Bologna, Florence, Rome and Naples, the second runs from Turin to Venice via Milan and Verona, and is under construction in parts. Trains are operated with a top speed of 300 km/h (190 mph).

The FS E.444 is a class of Italian railways electric locomotives. They were introduced in the course of the 1960s until 1975. Starting from 1989, all E.444s were upgraded as E.444R.

The E.464 is a class of Italian railways electric locomotives. They were introduced in the course of the 1990s for hauling light trains, especially for commuter service. They were acquired by FS Trenitalia to replace the old E.424 and E.646, dating from the 1940s and 1950s. The class was originally designed by ABB Trazione, later ADTranz, and produced in the Italian plant of Vado Ligure.

The FS Class E.491 and E.492 were an Italian electric 25 kV 50 Hz AC locomotives built during the 1980s by the TEAM consortium, formed by FIAT ferroviaria, Ansaldo and other companies. The lines of the locomotive were designed by Italian designer Giorgetto Giugiaro. Group E.491 was designed to be used on freight trains while E.492 was designed for fast passenger trains.

E.402A/B is a class of electric locomotives mainly used on medium speed passenger trains by the Italian railway company FS Trenitalia.

The FS Class D.443 is a class of diesel-electric locomotive used in Italy, introduced in the late 1960s and still in service.

The Trenitalia ETR 700, originally NS Hispeed V250, is a high-speed train designed by Pininfarina and built by AnsaldoBreda originally for NS International and NMBS/SNCB to operate on the Fyra-service, a high speed train between Amsterdam and Brussels with a branch to Breda on the newly built HSL-Zuid in the Netherlands and its extension HSL 4 in Belgium.

Fyra was an international high-speed rail service between the Netherlands and Belgium using the AnsaldoBreda V250 train. The service used the HSL-Zuid and HSL 4 railway lines to connect Amsterdam, Schiphol Airport, Rotterdam, Antwerp and Brussels. Continuous technical difficulties suspended the service, and it was eventually permanently halted due to reliability and safety concerns.

The Brenner Railway is a major line connecting the Austrian and Italian railways from Innsbruck to Verona, climbing up the Wipptal, passing over the Brenner Pass, descending down the Eisacktal to Bolzano/Bozen, then further down the Adige Valley to Rovereto/Rofreit, and along the section of the Adige Valley, called in Italian the “Vallagarina”, to Verona. This railway line is part of the Line 1 of Trans-European Transport Networks (TEN-T). It is considered a "fundamental" line by the state railways Ferrovie dello Stato (FS).

ETR 500 is a family of Italian high-speed trains built by AnsaldoBreda and introduced in 1993.

The FS Class E.405 is a class of electric locomotive built in 42 units by ADTranz originally for the Polish State Railways (PKP), but later acquired by Trenitalia Italian state railways.

The Frecciarossa 1000, is a high-speed train operated by Italian state railway operator Trenitalia. It was co-developed as a joint venture between Italian rail manufacturer Hitachi Rail Italy and multinational conglomerate Alstom. Both design and production work were divided between the two partner companies.

Le Frecce is the high-speed rail train category operated by Trenitalia in Italy.
