Development

The seven examples of this class were designed by Patrick Stirling for the GSWR and were built by Neilson and Company (Works Nos. 398-404) between November and December 1857. They were numbered 9, 14, 15, 17, 20, 30, and 33.[1] The members of the class were fitted with domed boilers and safety valves over the firebox.

Withdrawal

No 174 was withdrawn after an accident at Dalbeattie in 1874, and No.20 suffered a boiler explosion at Springhill, Glasgow in March 1876. The remainder were withdrawn by James Stirling between 1874 and 1876.
