In the most spectacular section of the UNESCO World Heritage Albula, the spiral tunnels and loops between Bergün and Preda. In the foreground the Albula creek with the Albula I viaduct, in the background the Rugnux viaduct with the sledgers train, pulled by Ge 4/4 II # 630. This sledgers train is circulating hourly between Bergün and Preda, to fil the gap between the hourly Regio Express trains. The 6 kilometers long sledgers run on the Albula pass road from Preda down to Bergün is very popular in wintertime.
