The Jacobite steam train is captured on camera as it travels over the Glenfinnan Viaduct. Vloggers Geoff and Vicki, having explored all 2,567 railway stations in Britain, hop aboard the Caledonian Sleeper for a round trip to Corrour, the highest station in the UK, in just 24 hours. Meanwhile, a group of engineers races against time to install the largest landslide barrier in the UK, as a potential slip endangers a part of the renowned West Highland Line.
