Its first shed allocation was Old Oak Common; from June 1952 to February 1956 it was based at Carmarthen, before returning again to Old Oak Common. Like all other steam locomotives based there, with the dieselisation of Cardiff Canton TMD it was transferred to Cardiff East Dock shed in September 1962, its last shed allocation.
It was withdrawn in December 1963, and acquired by Woodham Brothers scrapyard in Barry, South Wales in June 1964.[1]
