The Rhaetian Railway is a Swiss transport company, who owns the largest network among all private railway operators in Switzerland. The RhB operates on almost all the railway lines of the Swiss Canton of Graubünden/Grisons, except the Swiss Federal Railways (SBB-CFF-FFS) which operates trains to the cantonal capital,Chur. Inaugurated in 1888 and expanded from 1896 onwards in various sections, the RhB network is located almost entirely within Graubünden, with one station across the Italian border at Tirano.

The Rhaetian Railway serves a number of major tourist destinations, such as St Moritz and Davos. One of the RhB lines, the Bernina Railway, crosses the Bernina Pass at 2,253 m above sea and connects with the Italian railway network at TiranoLombardy.

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.
