The train journey is unique. The train crosses a beautiful countryside of mountains and lakes and will climb from 500 up to 1560 meters above see level. The train called "Rhätische Bahn" between Landquart and Davos has been running since 1890.
"The idea of building a mountain railway in the Grisons / Graubünden region first arose in 1888. Thanks to the initiative of a Dutchman named Willem-Jan Holsboer, the narrow-gauge railway company Schmalspurbahn Landquart–Davos AG was founded. The ceremonial first sod of turf was cut in that same year, and steam trains began to ply the route from Landquart up to Davos in 1890."
"Precipitously struggling ever upwards, with no end apparently in sight", is how the famous author Thomas Mann described a journey up into the "holy phantasmagorical world of towering summits".
