49 entered service on the Great North of Scotland Railway in October 1920 as part of a batch of engines built by the North British Locomotive Co Ltd. It is one of the class that was designated as GNoSR class F as it was one of the later engines which Heywood introduced with superheating as a development of the earlier Pickersgill locomotives.
It spent its working life up to withdrawal for preservation in 1958 working in GNoOR territory. During its life under BR ownership it was based at Kittybrewster until it moved to Keith in June 1951 from where it was withdrawn in June 1958 as the last working member of the class.
The locomotive was observed working between Elgin and Banff in the early 1950’s in a very poor condition with the only clean part of it being the nameplate.
It was then restored at Inverurie Works and although it was one of the later superheated batch, it was painted in the pre-Heywood green GNoSR livery (which it never carried as it was built in 1920 after Heywood introduced his black livery) and renumbered 49
It was then based at Glasgow Dawsholm shed and worked on special trains until June 1966 when it was placed in the Glasgow Transport Museum. It is currently on loan to Scottish Railway Museum at Bo’ness on the Bo’ness & Kinneil Railway.
