Michael Portillo boards the West Highland Line to begin a railway journey across Scotland’s central belt, from the Arrochar Alps to the Loch of the Lowes.

At the head of Loch Long, Michael meets a legendary octogenarian munro-bagger. In Balloch, on the shores of Loch Lomond, he joins passionate volunteers working to restore an iconic 1950s paddle steamer.
