Changes

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.
