The CGR class C1 and C1a were steam locomotives of the Garratt type built by Beyer, Peacock and Company for the Ceylon Government Railways (CGR), now Sri Lanka Railways. The Class C1 prototype was built in 1928 and was followed by 8 Class C1a locomotives in 1946. The C1a class was converted to oil firing between 1950 and 1954.[1]

Dimensions are shown in the table (right). Particulars of the boilers are not known but it is likely that the C1a had a significantly bigger boiler than the C1. The evidence for this is that the C1a was 6 long tons (6.1 t; 6.7 short tons) tons heavier than the C1, although it carried 1 long ton (1.02 t; 1.12 short tons) less fuel and about 2 long tons (2.03 t; 2.24 short tons) less water.
