the NBLs extinct by October. Several of the BR Class 42s soldiered on into 1972 and the last were withdrawn by the end of the year. Many withdrawn examples were hastily cannibalised for spare parts to keep the others going as stocks had been reduced in anticipation of a swifter end to D800 operation than was in the event possible. The "Cornish Riviera Express" remained booked for two D800s until the May timetable change in 1970. The early withdrawal dates meant that TOPS numbers were never worn, although the Swindon-built locomotives were allocated TOPS Class 42 and the NBL examples Class 43. D829 Magpie had gained celebrity status due to its appearance on the popular TV show of the same name and there was an attempt to preserve the engine. But the plans to save the engine were unsuccessful and the locomotive was scrapped. Post-BR use and preservation D821 'Greyhound' Around 1971, an approach was made by the Diesel Traction Group seeking to purchase Class 22 D6319. A price was agreed, but before the new owners could retrieve their purchase, it was accidentally scrapped at Swindon Works. British Railways, embarrassed, offered the would-be owners their choice of the remaining Warships (D810, D812, D821 and D832) for the same price. D821 was chosen as it was in the best mechanical condition and thus became the first preserved ex-BR main line diesel locomotive. D821 entered preservation on 24 May 1973. D818 'Glory' D818 became a "pet" of the employees of Swindon Works and was repainted from Rail Blue with full yellow ends back into its original green livery. There was some hope that it would eventually be preserved, but this did not happen, and the locomotive was scrapped before the works closed in 1985. D832 'Onslaught' D832 was sent to the Railway Technical Centre at Derby where it was used for various research purposes until it too was secured for preservation while the others were scrapped. D832 was restored to full operational order using many of the parts from D818 and it is doubtful whether there would have been enough components available to restore both D818 (which was missing several major items) and D832 without an expensive search for compatible German items, although this scenario became reality in September 2001 when D832 was fitted with a Mekydro transmission which was sourced from an ex-DB locomotive in Germany. Both locomotives are operational, D821
