The Regional Bus and Rail Company of Ticino (Italian: Ferrovie Autolinee Regionali Ticinesi SA, known by its Italian initials FART) is a limited company in the Swiss southern canton of Ticino, which provides the urban and suburban bus network in and around Locarno in Switzerland.

Together with the Italian company Società Subalpina Imprese Ferroviarie [de] (SSIF) they operate the railway between Locarno and Domodossola, known as the Centovallina in Switzerland and Vigezzina in Italy.

2004 SSIF ordered three three-car panoramic multiple units from the Officine Ferroviaire Veronesi and Škoda Works.

On 12 November 1918 Italy and Switzerland had signed a contract[2] about the construction of a narrow gauge railway, Locarno - Domodossola.

This contract fixed the cross acceptance of Italian vehicles in Switzerland and vice versa without needing a second approval.
