G&SWR 131 Class

The ten examples of this class were designed by Patrick Stirling for the GSWR and were built by R and W Hawthorn (Works Nos. 1222-31) in 1864. They were numbered 131–40.^[1] The members of the class were fitted with domeless boilers and safety valves over the firebox, these were later replaced by those of Ramsbottom design over the centre of the boiler following a boiler explosion at Springhill in 1876.^[2] The original weather boards were also replaced by Stirling cabs.

Eight of the class were rebuilt as 0-4-2 tank locomotives between 1880 and 1886.

The locomotives were withdrawn between 1883 and 1895.
