Infrastructure

Key figures

The 384 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.

This means that the RhB need to invest large sums every year to maintain the substance of its infrastructure. In 2016, the RhB invested approximately 182 million Swiss francs in infrastructure.

Der Langwieserviadukt ist mit 285 Metern Länge der längste Viadukt der RhB.

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