The train runs 434 km. in almost fifteen hours (round trip)

The railway line has 29 bridges, 21 tunnels, 13 viaducts, 2 spirals and 2 zigzags.
Because of the design decision of not using a rack-and-pinion for traction,
the route had to be designed to avoid steep grades.
The zigzags allow the train to climb up driving back and forth parallel to the slope of the mountain.
