The Rhaetian Railway (German: Rhätische Bahn, Italian: Ferrovia Retica, Romansh: Viafier Retica), abbreviated RhB, is a Swiss transport company that owns the largest network of all private railway operators in Switzerland. In 2008, the RhB section from the Albula/Bernina area (the part from Thusis to Tirano, including St Moritz) was added to the list of UNESCO World Heritage Sites. The Albula-Bernina line is the first rail line in the world to be photographed and put on Google Street View.
