Strade Ferrate della Sicilia / FS 2-6-0 Locomotives in Italy
Class Details by Steve Llanso of Sweat House Media
Class Gruppo D / Gruppo 902 (Locobase 6213)
Data from the Rete Sicula website [
] ... (visited 5 July 2004). These Moguls had surprisingly small drivers and were rated at 40 km/h (25 mph). At the time of the Ferrovie dello Stato's creation in 1905, all of the class were shedded at Caltnissetta.
