Ceylon Government Railway S1

The Ceylon Government Railway S1 was a class of three diesel multiple unit train sets that English Electric built for the Ceylon Government Railway, now Sri Lanka Railways. The units reached Ceylon in 1938 and were named Silver Foam, Silver Spray and Silver Mist; their inaugural run from Colombo Fort station to Galle took place on 25 February 1938, and they were used only on the Coastal Line. They served for about nineteen years before being withdrawn and scrapped in 1955. Later that year two diesel locomotives of the Class M3, numbers 589 and 590, were built locally using the prime movers of the scrapped S1 sets.
