It was chartered by the Midland area of the Stephenson Locomotive Society and carried more than 220 railway enthusiasts. The class were withdrawn between 1962 and 1967. Four have survived to preservation, these engines being: 41241, 41298, 41312 & 41313. All four members of the class have steamed in preservation with 41241 & 41312 working on the main line. 41241 appeared at the Rail 150 Cavalcade at Shildon in 1975 arriving at the event under its own power. It was also used on the Shildon shuttle trains during the event taking people from the main station at Shildon to the event and also between Darlington and Shildon. 41312 ran on the main line in the late 1990s/early 2000s. As of 2018 all four preserved engines are currently operational, the latest of them being 41241 which returned to service from an overhaul in June during the KWVR's 50th anniversary steam gala. No.41241 is particularly associated with the Keighley and Worth Valley Railway and when initially preserved was painted in a fictitious maroon livery with K&WVR on the tanks, though it was later restored to more conventional BR black. During October 2006, the Ivatt Trust loaned the unrestored no. 41313 to the Isle of Wight Steam Railway. In October 2014, it was announced that the engine will be moved to the East Somerset Railway for overhaul. No 41298 was also moved to the Isle of Wight, and ownership of both these locos was transferred to the Isle of Wight Steam Railway. These locomotives required conversion/fitment of air braking alongside the vacuum brakes as the rolling stock on the island is air-braked. All of the engines apart from 41241 wear authentic British Railways lined black livery with the later BR crest. 41241 presently wears the livery that it wore when the Keighley and Worth Valley Railway was opened in 1968, at the time it wasnt able to wear BR colours. Bachmann produced a 00 gauge model in various liveries. Dapol have released a model in British N gauge. Arthur from Thomas & Friends is based on this class.
