BR Class 42 D821 Greyhound
The Post-War BR Modernisation Plan called for the introduction of a range of Diesel locomotives. Although the majority were diesel electric, the Western Region at Swindon developed the B-B diesel-hydraulic Class 42 ‘Warship’ class (all bar two of the class being named after Royal Naval vessels). D821 is one of two preserved examples of the 38 originally built.The last HMS Greyhound (H05) was a G-class destroyer, launched in 1935 and sunk by German dive bombers in 1941 in the battle for Crete, with the loss of 100 lives. An earlier HMS Greyhound, a Greyhound-class destroyer, also saw service from 1900 to 1919. A number of other Naval vessels have also carried the name.

D821 in preservation
D821 was bought by members of the Diesel Traction Group, becoming the first main line diesel to be sold for preservation. In May 1973 D821 moved under her own power to Didcot, moving again in the following year to a private siding in Reading. Between February 1977 and April 1981 the locomotive underwent an overhaul at Swindon, and then moved to the North Yorkshire Moors Railway. She finally arrived on the SVR in September 1991.
An overhaul commenced in 2014. After a long period under repair at Old Oak Common (OOC) she returned to the SVR after the OOC open day in September 2017, before returning to use in April 2018 in time for the following month's Spring Diesel Festival.
