World's Most Scenic Railway Journeys S01E06 - Switzerland

Bill Nighy narrates a journey that starts at Tirano and climbs up through the Italian Alps and lakes through into Switzerland, taking in the Landwasser Viaduct. At Disentis, the train track changes to a cog railway as the gradient gets steeper, and a much bigger engine is added to climb the steep mountain route. The journey then reaches its conclusion at Zermatt, sitting at the base of the majestic Matterhorn.
