The Landquart-Chur-Thusis-Filisur-Bergün-St. Moritz line is where the magic happens. On the open-top RhB wagon, you can almost reach out and touch the sky. You'll feel like you're on a rollercoaster or a ghost train as you pass through the dizzying loop tunnels, but on the viaducts it's more like being in a cable car. Plenty of fresh air and variety are guaranteed. Visitors who prefer a more nostalgic experience shouldn't miss a ride in the open wooden panorama cars. The classic “Crocodile” locomotive carries families and railway fans to the Albula Valley. Open-top panorama carriages or traditional wooden carriages take visitors through the mountainous Domleschg valley over the famous Solis and Landwasser viaducts or through the loop tunnels between Bergün and Preda.
