Episode Details

George Stephenson was born into deep poverty in Wylam, Northumberland, in 1781, could not read until 18, and paid for night school by mending shoes and fixing clocks. This deep dive follows how his hands-on mechanical intuition, personal tragedy and sheer stubbornness carried him from colliery engine man to the father of railways, despite relentless snobbery from the scientific establishment.

The episode covers his miner's safety lamp and bitter dispute with Sir Humphry Davy, the Blucher locomotive and flanged wheel adhesion, the Stockton and Darlington Railway, and the Liverpool and Manchester Railway, including the floating track across Chat Moss and the Rocket's fire tube boiler at the Rainhill Trials. It closes with his later conservatism, straight cucumbers and the origin of standard gauge.

• How fixing a failing pumping engine at High Pit in 1811 turned an engine operator into an engine wright
• Why the Geordie lamp's tiny air holes made it safer than Davy's wire gauze design, and how elite prejudice shaped his son Robert's education
• How smooth wheels, locomotive weight, wrought iron rails and bogies made steam haulage practical
• Building a railway across a bottomless peat bog and the tragic death of William Huskisson on opening day in 1830
• Why the four foot eight and a half inch Stephenson gauge, taken from local coal carts, became the global standard
