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 remains of Bradshaw's Britain, as his journey follows the route of the Irish Mail from Ledbury to Holyhead.

Michael takes a tour of Chester's Roman remains and discovers a secret World War II chemical weapons plant at Rhydmwyn. After spending the night in Llandudno, he goes mussel fishing on the beautiful Conwy estuary. Show less
