Michael Portillo takes to the tracks with a copy of George Bradshaw's Victorian Railway Guidebook. In a series of four epic journeys, Portillo travels the length and breadth of the country to see how the railways changed us, and what of Bradshaw's Britain remains. Michael is in Manchester to find out more about George Bradshaw himself. He also gets fitted for a trilby in Denton and learns how the railways helped to create a national institution - fish and chips.
