By 1922 when the Great Western Railway had taken control, it had run 483,189 miles, and by 1923 was given a major overhaul, receiving a new boiler from the West Yard Works.

The engine was named "Gordon", after the General of Khartoum, and was kept in immaculate condition in Hampshire, performing relatively light duties compared to its TVR working days.

It received a major overhaul in 1955, with minor alterations to its external design, but by 1959 it needed boiler repairs and was withdrawn from service in 1960.

In the 1983 the engine was restored to working order by the Caerphilly Railway Society and ran for about 7 years, until taken out of service to await routine boiler examination.

[citation needed] On 1 October 2019 the National Railway Museum and Welsh Railways Trust (Formerly Gwili Vintage Carriages Group) announced a three-year overhaul agreement to return it to steam in a £160,000 project, part-funded by a £18,000 grant from the Association for Industrial Archaeology.

This grant will be used to restore the rolling chassis of the locomotive, which includes original Taff Vale Railway components.
