Following withdrawal from service in July 1964 the locomotive was transported to the scrapyard at Barry in February 1965 and it remained there until July 1986.
Following its purchase the locomotive was moved to the North Yorkshire Moors Railway (NYMR) where the owner had an agreement in place with the railway which was intended would enable 3814 to be restored.
Good progress was made on the chassis and tender and the NYMR offered to overhaul the locomotive in order to include it in their operational plans for 2010.
Following a change in personnel the locomotive was moved out of a covered working area and stored out in the open.
In the summer of 2016 the tender was moved to Llangollen for its restoration to be completed.
The tender will be attached to 6880 Betton Grange until that locomotive has its own tender.
In September 2018 the locomotive moved out of the Grosmont yard for the first time in more than 30 years. It was towed to Pickering where it was put on a low loader and transported to Llangollen where its restoration is planned to be completed
Following the closure of Llangollen Railway Engineering the Llangollen Railway requested that the locomotive be moved away from Llangollen.
In February 2021 it was revealed that the locomotive would be moving to Northern Steam Engineering at Stockton for its restoration to be completed. The engine moved later that month. The tender will remain at Llangollen to be used by 6880 Betton Grange until that locomotive’s new tender is available.
