A walk with information panels on the first Heidi film made and its history.
With 39 tunnels, 55 bridges and a difference in altitude of 1123 metres, the Albula line of the Rhaetian Railway between Thusis and St. Moritz is a masterpiece of railway engineering. It was opened in 1903 after having been under construction for 5 years. The section between Preda and Bergün is one of the most spectacular stretches in the world and is a prime example of how the high alpine landscape was opened up.
Sited right in the middle of the ruggedly-romantic landscape of the upper Albula Valley, the Railway Heritage Educational Trail informs walkers about the spectacular course of the Rhaetian Railway in this section in an exciting and compelling manner. The trail leads to numerous loops, across daring bridges and to the many tunnels. Experience railway engineering at first hand.
