G&SWR 141 Class

The Glasgow and South Western Railway (GSWR) 141 class was a class of ten 0-4-2 steam locomotives designed in 1866. They were by Patrick Stirling's sixth 0-4-2 design for the railway.

Development
The ten examples of this class were designed by Patrick Stirling for the GSWR and were built by Neilson and Company (Works Nos. 1226-35) in 1866. They were numbered 141–50. 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. The original weather boards were also replaced by Stirling cabs.

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

Withdrawal
The bulk of the class, including all the rebuilds were withdrawn between 1900 and 1913. However, two examples survived into London Midland and Scottish Railway ownership and were withdrawn in 1923 and 1924 respectively.
