The Great Train Robbery was the robbery of £2.61 million (worth about £62 million in 2023) from a Royal Mail train travelling from Glasgow to London, on the West Coast Main Line, in the early hours of 8 August 1963. It took place at Bridego Railway Bridge, Ledburn, near Mentmore, in Buckinghamshire, England.
After tampering with the lineside signals to bring the train to a halt, a gang of 15, led by Bruce Reynolds, attacked the train. Other gang members included Gordon Goody, Buster Edwards, Charlie Wilson, Roy James, John Daly, Jimmy White, Ronnie Biggs, Tommy Wisbey, Jim Hussey, Bob Welch and Roger Cordrey, as well as three men known only as numbers "1", "2" and "3"; two were later identified as Harry Smith and Danny Pembroke.
