Dumbarton to Tyndrum

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 of Bradshaw's Britain remains, as he journeys up the west coast of Scotland from Ayr to Skye.

Michael explores the historic Dumbarton shipyards that built the Cutty Sark, visits one of Queen Victoria's favourite haunts, Loch Lomond, and goes hunting for gold in Scotland's mountains.
