Michael Portillo takes to the tracks with a copy of George Bradshaw's Victorian Railway Guidebook. He travels the length and breadth of the country to see how the railways changed the people of Britain, and what remains of Bradshaw's experiences today, as he journeys up the west coast of Scotland from Ayr to Skye.

Michael investigates one of the great geological mysteries of the 19th century - the parallel roads of Glenroy. Plus, he finds out how the Victorians put a weather observatory on the top of Ben Nevis and takes a steam train across one of the most spectacular viaducts in Britain at Glenfinnan. Show less
