Great Train Robbery (1964): Aylesbury trial

The Travelling Post Office moved registered mail and high-value packets between Glasgow and London. The 8 August train carried used notes being returned to London — a fact later used to explain both the size of the haul and why serials were hard to spend. The official £2.6 million is the figure this atlas uses; later inflation comparisons belong in money notes, not in the 1963 line.

Recovery was partial. Police found some money at Leatherslade and in later arrests. Large amounts were never returned to the Royal Mail or the banks. The convicted status of the people and the incomplete recovery of the cash are different columns, as at Antwerp. The train was halted at Bridego Bridge in rural Buckinghamshire. After the bags were taken, the gang went to Leatherslade Farm, which they had bought as a temporary base. Neighbours and a land search put police onto the farm days later. This page does not reconstruct how the train was stopped.

Fingerprints, stolen vehicles, witness sightings and the farm debris built the Flying Squad case. Jack Slipper and other Yard officers became English-language characters. The investigation is a 1960s detective story with names, not an unsolved puzzle. The 1964 trial at Aylesbury was a national spectacle. Edmund Davies's thirty-year terms for several robbers were meant as deterrence after a night that had injured a driver and humiliated the Post Office. Appeals softened some paths; the tariff still defined a generation of British crime sentencing talk.
