Description

These units arrived Ceylon (now Sri Lanka) in 1938. Only three units were ever built, and they were given the names Silver Foam (501), Silver Spray (502) and Silver Mist (503). Their inaugural run from Colombo Fort Station to Galle took place on 25 February 1938.^[3] These train sets were used only on the Coastal Line.

They served the Ceylon Government Railway for around 19 years before being withdrawn and scrapped in 1955. Later that year, two diesel locomotives classified as the Class M3 Nos. 589 and 590 were built locally using the prime movers of the scrapped S1 sets.
