Valle Seriana / FSE 2-6-2 Locomotives in Italy
Class Details by Steve Llanso of Sweat House Media
Class 37 (Locobase 6191)
Data from [
] (30 June 2004). This website celebrates the Ferrovie de Sud-Est; see Locobase 6186.
Originally built for the FVS in 1929, the pair of Prairie tanks with Belpaire fireboxes went to the FSE in 1937 and ran on the Tricase-Nardo line into the 1950s. Then they went to the SATTI (railways of Canavese), but were found to be too long for the platforms.
Back they came to the FSE where they ran until 1972.
