The London and North Eastern Railway (LNER) Class V2 2-6-2 steam locomotives were designed by Sir Nigel Gresley for express mixed traffic work, and built at the LNER shops at Doncaster and Darlington between 1936-1944. The best known is the first of the class, 4771 (later 800 and 60800) Green Arrow, which is the only preserved example. Peter Tuffrey's book is an outstanding collection of rare colour and black and white images with informative captions that documents this most popular class of locomotive.
