Miles Kington explores the line laid from Bristol to Exeter by Isambard Kingdom Brunel and then travels through south Devon in all its glory. Along the way Kington examines the enormous task faced by Brunel in the design and construction of the Royal Albert Bridge, which carries the Cornish Main Line railway in and out of Cornwall. Perhaps less well known is the impact of the railway line and the rail company on promoting tourism in the Edwardian golden age of British seaside resorts.
