Key figures

The 385 km-long track network of the Rhaetian Railway also generates some fascinating and impressive figures: One third of the network is more than 1,500 metres above sea level. One third of the RhB network has UNESCO World Heritage status. One fifth of its lines pass through or over a feat of civil engineering. More than ninety percent of the track network dates from before 1914.

The 285 metres of the Langwieser Viaduct make it the longest structure of its type on the RhB.
