The Ferrovie dello Stato Italiane (FS; Italian State Railways) Class 310 (Italian: Gruppo 310), formerly Rete Mediterranea Class 380, was a 0-6-0 steam locomotive; they were the first Italian as-built compound locomotives.
After modifying six of the pre-existing Class 255 to a compound arrangement as an experiment, with positive results, the Ufficio d'Arte di Torino of the Rete Mediterranea designed a two-cylinder compound locomotive meant for mixed service; this design also saw the beginning of the adoption of the Walschaerts valve gear on Italian locomotives.
The round-topped boiler on the first 49 units had standard tubes; however, on the last 20 units it was replaced by one with Serve tubes, which brought the power of these locomotives from the original 430 CV (316 kW; 424 hp) to 500 CV (368 kW; 493 hp).
These locomotives were built between 1894 and 1901 by Ernesto Breda and MÁVAG. [1] [2]
The Class 310, while an important step in Italian locomotive design, was not a thoroughly successful design; the unique cut-off command for both cylinders made it difficult to equalize the work being done, the starting valve design did not prove entirely successful, and the proportions of the cylinders were also less than optimal. The need to obviate these inconvenients led to the development of the more successful Class 320.
The Class 310 locomotives served on both passenger and freight trains on secondary lines for their whole career; the last units survived till the early 1930s around Asti, but were withdrawn soon after. No locomotive survived into preservation. [3] [2]
The Ferrovie dello Stato Class 740 is a class of 2-8-0 'Consolidation' steam locomotives.
The Ferrovie dello Stato Class 685 is a class of 2-6-2 'Prairie' express train steam locomotives. These are colloquially known as Regine, mirroring their fame as one of the most successful and appreciated Italian steam locomotives.
The Ferrovie dello Stato Class 640 is a class of 2-6-0 'Mogul' steam locomotives in Italy. Commonly nicknamed "Signorine", a nickname shared with the similar Class 625, these locomotives were the first superheated steam locomotives in Italy.
The Rete Adriatica Class 500, classified after 1905 in the Ferrovie dello Stato Italiane as Class 670 was an unorthodox and iconic cab forward 4-6-0 (2'C) steam locomotive.

The Ferrovie dello Stato Class 480 is a 2-10-0 steam locomotive.
The Ferrovie dello Stato Italiane Class 650, formerly SFAI1181-1200 and Rete Mediterranea 300 Class, also known as "Vittorio Emanuele II", was the first steam locomotive in continental Europe to have the 4-6-0 'Ten-Wheeler' arrangement.
The Ferrovie dello Stato Italiane Class 680 is a 2-6-2 express steam locomotive; it was the direct ancestor of the very successful and appreciated Class 685.
The Ferrovie dello Stato Italiane Class 552, formerly Rete Adriatica Class 180 bis, is a 4-4-0 steam locomotive; it was the final development in Italy of the 'American' express locomotive type.
The Ferrovie dello Stato Italiane Class 600, formerly Rete Adriatica Class 380 and Società per le Strade Ferrate Meridionali Class 380, is a 2-6-0 'Mogul' steam locomotive; it is considered by some as the first Italian modern steam locomotive.
The Ferrovie dello Stato Italiane Class 835 is a 0-6-0T steam locomotive; it was the standard steam shunter of the FS.

The Ferrovie dello Stato Class 741 is a class of 2-8-0 'Consolidation' steam locomotives, rebuilds from the FS Class 740 with a Franco-Crosti boiler; it was the last class of steam locomotives introduced in Italy.
FS Class 400 were steam locomotives of French construction, built for service in Italy. They were 0-8-0 tender locomotives with two outside cylinders.
FS Class 910 were 2-6-2 tank locomotives designed by Guglielmo Cappa for Rete Sicula where they were registered as RS Class 400. They were absorbed by Italian State Railways (FS) in 1905 and became FS Class 910.
The Ferrovie dello Stato Class 745 was a class of 2-8-0 'Consolidation' steam locomotives.
The Ferrovie dello Stato Class 744 is a class of 2-8-0 steam locomotives; they were the last orthodox steam locomotives built for the FS.
