The establishment of the Rhaetian Railway traces back to Dutchman Willem Jan Holsboer, who proposed a railway line from Landquart to Davos in 1888. Holsboer founded the Lanquart-Davos AG to begin construction of a standard-gauge line, but the mountainous terrain lacked sufficient space.The Rhaetian Railway, abbreviated RhB, is a Swiss transport company that owns the largest network of all private railway operators in Switzerland.
