In the early hours of 8 August 1963 an armed gang of 15 men held up the overnight Glasgow-to-London Travelling Post Office train in what soon became known as The Great Train Robbery.
The robbers used four six-volt batteries to trigger a red light on the track.
When the train stopped, they coshed driver Jack Mills, uncoupled the engine and some carriages, and drove them further along the line to Bridego Bridge where they were loaded into a lorry in one of the most meticulously planned operations police had seen.
The gang – Stan Agate, Ronnie Biggs, Roger Cordrey, Buster Edwards, Gordon Goody, Jim Hussey, Roy James, Bill Jennings, Frank Munroe, Alf Thomas, Bob Welch, Jimmy White, Tommy Wisbey and Charlie Wilson – stole 120 bags containing used banknotes from the train. The notes were to have been pulped upon arrival in London.
Initial reports gave the haul as £1 million, but in fact, they netted mailbags worth more than £2.5 million.
Police soon found their hideout at a remote farm and identified the men responsible. Charlie Wilson was the first to be charged, later the same month.
Wilson escaped from Winson Green prison on 12 August 1964. He was recaptured in Canada on 25 January 1968.
Ronnie Biggs (pictured at left) escaped to Australia, where he ran a guest house in Adelaide before moving to Melbourne, where he worked as a carpenter. He fled finally to Brazil, in 1970.
