Walking Britain's Lost Railways

Rob Bell is in Yorkshire on the trail of a man once known as the 'Railway King'. George Hudson rose from farming origins to become Lord Mayor of York, and the greatest railway builder of all. Rob starts in York, which Hudson almost single-handedly turned into a railway city - home now to the National Railway Museum.

Rob Bell visits Cornwall, once one of the world's great industrial landscapes, and explores the copper mining that once dominated this peninsula. From north coast to south coast, Rob follows Cornwall's first two railways, and discovers how the deep mines they served prompted the invention of the all-important steam engine.

Rob Bell is in Kent following a quiet, rural line that exploded into prominence during two world wars. The Elham Valley railway once linked Canterbury to Folkestone via the chalk downs of the 'Garden of England'. As Rob discovers, the line was built as part of a tug of war between competing Victorian rail companies.

Exploring the lost railways of Northern Ireland, Rob travels along the route of its first railway to be built, from Belfast on the east coast, via Armagh, to Bundoran on the west coast.
