Cameras capture a route through Spain, beginning near Leon, part of the famous north Spanish Pilgrimage, in the Picos de Europa mountains. The railway then runs through the Basque country before the famous Guggenheim Museum greets travellers in Bilbao. In Galicia, the gorges, coastline and sea bridges are a sight for sore eyes, and a speciality cider tour refreshes the train's guests. The journey ends in Ferrol, a spectacular harbour that has been a major shipbuilding centre for most of its history and has been a key city in many wars.

A trip through Wales' highest peaks and deepest valleys. Starting in Pwllheli in the north west, the route heads along the lines that were built during the slate industry's heyday. At Porthmadog, the journey briefly switches to the reconstructed steam trains of the Welsh Highland National Heritage Railway to Minffordd station. Nearby is the village of Portmeirion, famous for its role in the classic TV series The Prisoner. Rejoining the Cambrian Line, local farmers reveal what the railway means to them, before the route takes in the seaside resort of Aberdovey.
