Brusio Spiral Viaduct
Bernina Express train attracts the travellers due to the spiral viaduct located near Brusio (Switzerland). The high-speed train loops the loop owing to specific tracks construction: railroad lays over the circular arch bridge, then under it through the highest arch. Such signature structure was built in 1908 aiming at lowering the rails’ height for 17 m above sea level.
This part of the Rhaetian Railway was listed as the UNESCO World Heritage Site; that is why the tourists travelling by Bernina Express should not be worried about the condition of the loop viaduct and their own safety.
