Some of the locomotives were from Strade Ferrate dello Stato Piemontese (SFSP).

While another 18 units had been built for the Società per le strade ferrate dell'Alta Italia (SFAI).

In 1865 they all passed to the SFAI, which had absorbed all the various local companies and the former Piedmontese state railways.

The first three, named Archimede, Diodoro and Novelli, inaugurated the Palermo - Bagheria line, the first railway section on the island of Sicily, on 28 April 1863.

In 1905, the Ferrovie dello Stato registered only 25 units and assigned them to Class 113, with numbers from 1131 to 1155.
