Società Nazionale Officine di Savigliano

In 1869, with the transfer of ownership of the line to the Società per le Ferrovie dell'Alta Italia (SFAI), the workshop was closed.

On 17 July 1880 the Società Nazionale Officine di Savigliano was founded in Turin, with headquarters in Savigliano, which rapidly expanded to take on 640 employees and make a monthly production of over fifty rolling stock units commissioned by various railway companies such as SFAI, Ferrovie Romane and Compagnie Internationale des Wagons-Lits.

In 1889, SNOS merged with the Società Anonima Italiana Ausiliare, a Turin-based company competing with the related facilities located in Corso Mortara near Torino Dora station.

This led to a further expansion of production that, on the threshold of the First World War, also embraced electrical and mechanical machinery as well as metal constructions such as bridges and viaducts in many foreign countries.

Like other large industries, Savigliano's plants had suffered war damage but, by 1948, it had resumed supplies to the State Railways that were commissioning the production of rolling stock of all kinds.
