While the modern network prioritises velocity, specific corridors are engineered to respect the topography. These lines feature spiralling viaducts, narrow gauges, and panoramic carriages designed entirely to interface with the enduring landscape outside.

Bernina Express

Connecting Chur in Switzerland to Tirano in Italy, this narrow-gauge marvel scales the Bernina Pass without the aid of rack-and-pinion mechanisms. It navigates 55 tunnels and 196 bridges, representing a triumph of early 20th-century gradient engineering.
