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 across the British railway network. They were built at the LNER workshops in Doncaster and Darlington between 1936 and 1944. The best known example is the first of the class to be constructed: 4771 Green Arrow, which is now the only example of the class in preservation.
