Preda

Highlight • Settlement

Beautiful area also good for sledging in winter

The railway line through the Albula Valley is also known as the Albula Railway Carousel. The side of the valley is constantly changed in several spiral tunnels and viaducts. The viaducts on which the Albula is crossed do not have names. They are simply numbered. Viaduct number one is particularly spectacular because after a spiral tunnel the line reappears above.

Rugnux Tunnel

Highlight • Structure

The Rugnux Tunnel is the lowest circular loop tunnel of the Albula Railway on the Bergün-Preda section in the canton of Graubünden (Switzerland). It has a length of 662 meters. The three roundabout tunnels and four Albula viaducts (crossing the valley) allow the gain in height, whereby the principle of an adhesion track (static friction of the wheels) comes into play here.

Historic Center of Bergün

Highlight • Historical Site

Formerly a place where people changed horses and spent the night. After the completion of the Albula Railway, they were excited to compete with St. Moritz and built a magnificent spa hotel. But the tourists stayed away and so Bergün was spared real estate speculation and is largely authentic today.

Between Bergün and Preda lies the most astonishing section of the railway line to St. Moritz: After leaving Bergün, you can see the village three more times, albeit from higher and higher. In the mountain, the train travels upwards in a spiral tunnel. Alighting in Preda, you walk back to Bergün on the beautiful railway adventure trail and learn a lot about the difficult construction of this section of the route.

Farm Shops in Guarda

Highlight • Rest Area

One in a wagon; the other classic as a sales stall. Wonderful for a rest - sit on skins and enjoy regional products.

Albula Railway Adventure Trail

Highlight (Segment) • Trail

The 63 kilometer long line, which is one of the world's most spectacular narrow gauge railways with 55 bridges and 39 tunnels, is part of the Rhaetian Railway (RhB) trunk network. The construction of the Albulabahn was started in September 1898, the opening took place on July 1, 1903 and the extension to St. Moritz went to 10 July 1904 in operation.

On 7 July 2008, the Albula and the Bernina Railway were included in the list of UNESCO World Heritage Sites.

The following sequence is recommended for your hike: First visit to the railway museum in the station of Bergün, not only instructive, but lovingly made and instructive. The subsequent route you go with different eyes.

Then take the train to Preda and walk comfortably downhill to Bergün, always somehow between train and road, which lead over, under and around you. Impressively.
