Robbers Who Stopped A Train
In this post
At about three in the morning, the signal ahead turned red.
Jack Mills did what a careful train driver is trained to do. He slowed the overnight Royal Mail train and brought it to a stop in the dark Buckinghamshire countryside. There was no station. There was no warning of trouble. The line from Glasgow to London should have carried him onward through the night.
The red light was a lie.
Men were waiting beside the track. Within minutes, Mills had been struck on the head, his co-driver had been attacked, and part of the train had been separated from the rest. A gang of fifteen, organised by Bruce Reynolds, had come for the used banknotes travelling south to be taken out of use and destroyed.
The amount they stole is usually given as about £2.6 million. The National Archives puts it at over £2.63 million. It was a record haul in Britain at the time, and most of the money was never recovered. Yet the robbery should not be remembered as a clever adventure. It left a working man injured, frightened postal staff in the dark, and a trail of evidence so clear that the gang’s hiding place became known as one big clue.
Move one — Make the signal lie
The train was a Travelling Post Office. Staff on board sorted letters and parcels as it travelled. Near the front was a High Value Package carriage carrying registered mail, including a large amount of cash. A Scottish bank holiday weekend had helped swell the value on board far beyond an ordinary night, according to British Transport Police.
The gang used inside information about the train’s movements. Reynolds is widely described by Thames Valley Police as the mastermind who chose the men and planned where the train would be stopped: Sears Crossing, between Leighton Buzzard and Cheddington.
The trick itself was simple. A glove covered the real green signal. A battery powered a red light. To a driver approaching at speed in darkness, the message looked plain and urgent: stop.
That simplicity is part of what made the plan dangerous. Signals are commands drivers must trust. A false signal turned a safety system into a trap. Mills could not know that obeying the light was exactly what the robbers needed him to do.
The gang also cut the nearby telephone cables. When co-driver David Whitby climbed down to use the line-side phone and report the problem, he found the line dead. As he turned back, robbers attacked him and threw him down the steep embankment.
Move two — Stop, split, and take control
Masked men swarmed around the locomotive. One climbed into the cab and hit Mills over the head, knocking him unconscious. Other robbers uncoupled most of the train, leaving the engine and the first two carriages — the section holding the high-value mail.
More than seventy postal workers were in the carriages left behind. Many did not realise what was happening. Staff in the front carriages were pushed aside and held while the gang took control.
No firearms were used. That fact is sometimes used to soften the story, as if a robbery without guns must have been gentle. It was not. Whitby had been thrown down an embankment. Mills had been struck on the head with enough force to knock him out. Postal workers were threatened and terrified. Violence does not need a bullet to change a life.
The blow to Mills matters in every part of what followed. Thames Valley Police record that he was bleeding heavily when the gang forced him back to the controls. He never fully returned to work after the robbery. He died in 1970, seven years later. His official cause of death was leukaemia, but his family insisted that the head injury and the ordeal contributed to his poor health and early death. Those two statements should be kept together: the medical cause recorded at his death, and the family’s firm belief about the damage done that night.
Move three — Force the train to Bridego Bridge
Sears Crossing was a bad place to unload heavy sacks. The ground fell away in steep banks, and vehicles could not work easily beside the train. The gang had selected Bridego Bridge, a short distance farther along the line, where Land Rovers and other vehicles could wait near the road.
First, though, somebody had to move the engine and its two carriages.
The gang had expected one of its own men to do that job. He had spent time around railway staff and had some experience with trains, but the large diesel locomotive in front of him was very different from the smaller machines he knew. When he climbed into the cab, he realised he could not drive it.
So the plan bent back toward cruelty. Ronnie Biggs helped rouse the injured Mills. Mills, bleeding from the head wound, was forced to drive the short section of train to Bridego Bridge himself.
At the bridge, the robbers formed a human chain. British Transport Police describe 120 sacks holding about two and a half tons of money being passed from the train to the waiting vehicles. Reports differ on whether the drive to the bridge was about half a mile or nearer a mile, but the scene is clear: a line of men in the dark, moving sack after sack as fast as they could.
Before leaving, one robber ordered the postal staff to stay where they were for thirty minutes before raising the alarm. That warning was meant to buy time. Instead, it told investigators something useful: a gang asking for half an hour probably had a hiding place within roughly half an hour’s drive.
Move four — Hide at Leatherslade Farm
The vehicles carried the money to Leatherslade Farm, near Oakley. The farmhouse had been obtained as a hideout where the gang could divide the cash and stay out of sight while police searched the country.
For a short time, the plan held together. The men shared out the money. Biggs’s share is given by British Transport Police as £147,000, a fortune in 1963. The gang even played Monopoly using real stolen banknotes.
Then nerves began to undo them. Their intention had been to lie low for weeks. Low-flying RAF aircraft passed nearby on training flights, and the robbers feared the planes were part of the hunt. News reports about police searching farmhouses added to the pressure. Thames Valley Police say wrong reports about the search radius — thirty miles in the media rather than the thirty-minute idea investigators were using — helped scare the gang into leaving earlier than planned.
Leaving early created a second problem. A man hired to burn the farmhouse and destroy what the gang left behind did not do the job; Thames Valley Police say the hired accomplice failed to keep his word. The building was never cleaned of evidence.
When police reached the farm, the men were gone, but their rushed stay remained: food and provisions, sleeping bags and bedding, banknote wrappers, postal sacks, and registered mail packages. The gang had taken the money and left behind a map of itself.
Move five — Let the fingerprints speak
A nearby resident had become suspicious about activity at the farm and contacted police. Officers searched the house and outbuildings carefully. Fingerprint specialists photographed and examined the ordinary objects a group of men had touched while eating, drinking, sleeping, and passing time.
The most famous object was the Monopoly board. British Transport Police say fingerprints were found on the board and on a tomato ketchup bottle. The National Archives highlights the same unlikely pair: a board game and a kitchen bottle helped connect Ronnie Biggs to the crime. The joke of playing Monopoly with real money had become evidence.
Other prints and enquiries led police from man to man. The gang that had worn masks at the track could not hide the hands it had used at the farm.
The sentences were severe. British Transport Police give a combined total of 307 years for the gang. Biggs received thirty years. Reynolds stayed free for five years before he was caught; when sentenced, he received ten years, according to British Transport Police.
Ronnie Biggs became the name the public remembered longest. After serving only about fifteen months, he escaped from Wandsworth Prison in 1965, leaving in a furniture van. He travelled abroad, eventually reached Brazil, and stayed outside British prison for decades. In May 2001, after serious health problems, he returned to the United Kingdom and was arrested and sent back to prison. He was released on compassionate grounds in 2009.
The cost that should not be forgotten
Public memory often keeps the neat parts: a false signal, a stopped train, a farm, a board game. The human cost is less tidy.
David Whitby was only twenty-five when he was attacked and thrown down the embankment. Thames Valley Police say he also struggled to come to terms with the robbery. He died from a heart attack in 1972, aged thirty-four.
Jack Mills’s story is the one that should stay at the centre. He was a driver doing his job on an ordinary night run. He stopped for a signal because that was the safe and correct thing to do. For obeying it, he was beaten, forced to drive while bleeding, and left with an injury and a trauma from which, by his family’s account and by the record of his working life, he never fully recovered.
In my view, the word “great” in Great Train Robbery describes the size of the theft, not the worth of the men who did it. The money was huge. The planning was detailed. Neither fact makes the crime admirable. A gang stole a record sum and then proved, at a farmhouse table, that it could not even hide its own fingerprints. Mills paid for their night’s work long after the sacks had been emptied.
Common questions
Why did the gang choose that train? It was an overnight Royal Mail train carrying sorted high-value packages, including used banknotes travelling from Glasgow toward London to be withdrawn and destroyed. Inside information told the gang when and where the valuable carriages would be.
Did the robbers use guns? No. British Transport Police state that no firearms were used. The robbery was still violent: Whitby was thrown down an embankment and Mills was struck on the head and knocked unconscious.
How did police find Leatherslade Farm? A nearby resident reported suspicious activity. Investigators also had the clue from the thirty-minute warning, which suggested a hideout within about thirty minutes of the bridge. At the farm, police found abandoned supplies, mail material, and fingerprints.
What happened to Ronnie Biggs? Biggs was sentenced to thirty years, escaped from Wandsworth Prison in 1965 after about fifteen months, lived abroad for decades, mainly in Brazil after travelling through other countries, returned to Britain in 2001, went back to prison, and was released on compassionate grounds in 2009.
Was Jack Mills killed by the robbery? Mills died in 1970 from leukaemia, seven years after the attack. He had been struck on the head during the robbery, was forced to drive while bleeding, and never fully returned to work. His family believed the injury and trauma contributed to his decline and early death.
