The Rhaetian Railway (RhB) is a Swiss transport company that owns the largest network of all private railway operators in Switzerland. The RhB operates all the railway lines of the Swiss canton of Graubuenden. Inaugurated in 1888 and expanded from 1896 onwards in various sections, the Rhaetian Railway serves a number of major tourist destinations, such as St. Moritz and Davos. On the model railway layout, we see the RhB station in Alp Gruem, Swiss landscapes and model trains made by BEMO. All Rhaetian Railway lines are 1,000 mm (3 feet 3 3⁄8 in) metre gauge wide and electrified. In 1/87 rail transport modelling scale, these 1,000 mm railway lines are called H0m or HOn3½ with a track gauge of 12 mm (0.472 in).
