Port Talbot to Milford Haven

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 explores the Victorian railway legacy behind the steel works of Port Talbot, follows the trail of 19th-century waterfall hunters in Neath and uncovers the fascinating whaling past of Milford Haven.
