Odney Manor was built in Swindon by British Railways to a Great Western Railway design in 1950. It is one of 9 locomotives preserved from the class, which originally had 30.
After a period of running in, Odney Manor was put into store at the beginning of 1951. It entered service at Neath in early 1951, being officially allocated there in April and operated secondary duties in the Swansea area.
It was sent to Shrewsbury shed in 1952 and spent nine years there. It spent this time operating the Cambrian Coast Express between Shrewsbury and Aberystwyth, as well as local passenger and goods trains around the Shrewsbury area.
In 1961, it moved to Croes Newydd. From here, it operated in the Wrexham area, predominantly working from Chester and Wrexham to Barmouth and Pwllheli.
Two years later, it moved to Aberystwyth for a short period of time, operating from there to Carmarthen, Shrewsbury and Oswestry.
It was withdrawn from service in 1965, having completed 402,613 miles, before being moved to Woodham Brothers scrapyard in Barry in 1966.
It was rescued from Barry privately in 1981 and moved to the Gloucestershire Warwickshire Railway, where restoration was completed by 1987. It worked on the Gwilli Railway, Llangollen Railway and East Lancashire Railway before coming to the West Somerset Railway in 1995. Its owners sold it to the WSR in 2004.
In June 2011, it was temporarily renamed Norton Manor after 40 Commando's base alongside the railway at Norton Fitzwarren. Originally, the Great Western Railway had intended to give the name Norton Manor to new locomotive number 7830, but the order for this locomotive was cancelled.
7828 is painted in the BR lined green livery.
New for 2024, it has a newly rebuilt Churchward tender, T2061, with a 3500 gallon water capacity, which was built for 7828 by a volunteer team at Minehead workshop, which took over 3 years.
The boiler ticket for Odney Manor is due to expire in December 2028.
