In this episode, we follow in Harry Potter’s footsteps as we board The Jacobite steam train across the magnificent Glenfinnan Viaduct in the company of mother and son, Florence and Lewis McLean, who are the Guard and Fireman on The Jacobite. We join YouTube sensations, Geoff and Vicki, who have visited all 2,567 of Britain’s railway stations but now board the Caledonian Sleeper on a 24-hour return journey to the UK’s highest station at Corrour. We ride the footplate and share a cream tea on the restored Royal Deeside steam railway and we join two hundred lucky passengers aboard the A4 steam locomotive, Union of South Africa, on a farewell tour of Scotland as she bids farewell to the lines and landmarks she’s called home for the past 50 years.
