Michael Portillo takes to the tracks with a copy of George Bradshaw's Victorian Railway Guidebook. In a series of five epic journeys, Portillo travels the length and breadth of the country to see how the railways changed us, and what remains of Bradshaw's Britain.

Following the route of the Great Eastern Line, which ventures from the edge of East Anglia to the centre of the country's financial capital, London, Michael visits Essex to discover why dairy herds travelled there by rail from all over the country in the 19th century. He also visits Waltham Cross to see how the gunpowder made there fuelled the building of an empire and heads to Hackney to uncover the gruesome details of the first murder on a train. Show less
