31806 is the only survivor of the U class locomotives that was originally built as a K class 2-6-4T. It was originally built at Brighton as A806 River Torridge in 1926 but following the accident at Sevenoaks was rebuilt as a U class 2-6-0 at Brighton in 1928.
After entering traffic at Guildford it soon afterwards moved to Nine Elms early in 1929. It remained at Nine Elms until the late 1930s when it moved to Basingstoke and then Guildford by the beginning of 1945.

In November 1957 the engine received a new front-end section to its frames during a heavy overhaul.
After withdrawal from service in January 1964, having covered 970,103 miles, it was stored at Fratton before going to the scrapyard at Barry belonging to Woodham Brothers. It arrived at Barry in June 1964.
It was purchased in 1975 by John Bunch in 1975 and left Barry in October 1976 and moved to the Mid Hants Railway at Alresford where its restoration started in 1979 with the result that it was restored and returned to service in April 1981.
31806 ran on the Mid Hants Railway for a decade until the boiler certificate expired after which it remained out of service for many years. It finally returned to steam again on the Mid Hants Railway in 2011 and has a boiler certificate valid until 2021.
In 2014 the owner, John Bunch, moved it to the Swanage Railway who agreed a 25 year lease for the locomotive.
Operational SR Maunsell U class 2-6-0 No. 31806 is to arrive in time to start hauling trains at Swanage during August. The Brighton-built ‘U-boat’ as the class were nicknamed, ran on the Swanage branch in the 1950s under BR auspices. It has visited the line in the preservation era, most recently for the Swanage Railway’s April 5-6 2014 Spring Steam Gala. It has seven years remaining on its boiler ticket.
The locomotive is currently undergoing a bottom end overhaul at Herston works. Southern Locomotives Ltd have been contracted to carry out an overhaul of the tender frames which will included modifications to the pipework to bring it in line with the original drawings. The locomotive has been fitted out for main line electronic equipment with a view to the engine being able to work into Wareham at some stage in the future.
In April 2018 the locomotive hauled the Yeovil to Swanage segment of the Great Britain Xl. This was its inaugural main line running .
