The G. W. S. purchased the engine during the summer of 1975, and it left Barry on the evening of 21st March 1976, arriving at Didcot the following morning.

A group of G. W. S. members then formed the Heavy freight Group to restore the engine, which they financed themselves from sponsorship, donations and sales. It first ran again under it's own steam in June 1985. The livery it is now carrying (Black with G W R on the tender), is one that it had during the war years with the side windows sheeted over to reduce the risk of air attacks. The group has also made a replica of the blackout sheets that cover the back of the cab, but these are not used when the engine is running.

Once restored 3822 was used mainly at Didcot, although it did make several trips to other railways including the Nene Valley, West Somerset and East Lancashire. During 3822's stay on the Nene Valley it was also used for a Queen video, when you may have seen it burst through a brick wall, while towing Freddie Mercury and co.

3822 was taken out of service in 1995 for it's ten yearly boiler examination and overhaul and returned to traffic in 2002.
