Data from "Old Single Express Locomotive, G & SW Ry," The Locomotive Magazine, Volume IX [9] (24 October 1903), p. 246
Before he achieved his greatest fame on the Great Northern as England's foremost promoter of the passenger single-wheeler, Patrick Stirling served 13 years as head of the G & SW's locomotive department. Among his accomplishments was the establishment of locomotive production at Kilmarnock and it was there that he put together this design. The result was a bit chunky and bluff when compared to the sleekness and free-striding appearance of Stirling's later GNR classes.
