80151 was withdrawn from service in May 1967 after just over ten years of running on BR metal. It was sold to Woodham Brothers at Barry for scrap and arrived at the scrapyard in October 1967.
It remained at Barry until May 1975 following its purchase in 1974 by a group based in Essex. The locomotive was then moved to the East Anglia Railway Museum.
Restoration work proceeded slowly and in 1998 the locomotive was transferred to the Bluebell Railway where the restoration was completed and 80151 went into service in 2001.
The engine was withdrawn prematurely in late 2010 with leaking tubes. Boiler repairs were carried out in early 2011 and the locomotive returned to service. It was finally withdrawn from traffic in May 2012 following expiry of its boiler ticket. Work began on overhauling the locomotive in September 2015.
In September 2105 an overhaul of 80151 commenced with one of the first tasks being the removal of the driving wheels for re-tyring.
By early 2017 work on the overhaul had progressed to the state that the frames were ready for re-wheeling following the fitting of a new frame stretcher.
By September 2017 the locomotive had been re-wheeled with brake, lubrication and injector pipework being fitted. The earlier hope was to have 80151 operational in 2017 but this was later revised to 2018.
By the end of 2018 work on the bottom half was said to be 90% complete and the hope was that the locomotive would be back in service in April 2019.
In March 2019 it was reported that the boiler had passed its hydraulic and steam tests.
The locomotive underwent steam tests in June 2019 and and in the following month it commenced running in trials.
In October 2021 the locomotive left the Bluebell Railway for the first time in preservation when it went to the Mid Hants Railway for a short period.
