Michael Portillo takes to the tracks with a copy of George Bradshaw's Victorian Railway Guidebook. Portillo travels the length and breadth of the country to see how the railways changed us, and what of Bradshaw's Britain remains, as his journey goes through Kent, from London Bridge around the scenic south coast to Hastings.
Michael visits the Royal Observatory at Greenwich to see how the railways standardised time, takes a walk through the world's first underwater tunnel at Rotherhithe and explores the historic Dockyards at Chatham.
