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.

All this week he is travelling west, from Oxford in the heart of England, through the Malvern Hills and into Wales, taking in the unique Victorian heritage of the South Wales coastline.

Today Michael visits the home of Queen Victoria's favourite bishop in Hartlebury, sniffs out the secrets of a famous 19th-century sauce in Worcester and follows in the footsteps of Victorian health fanatics to the Malvern Hills. Show less
