Preda railway station is a railway station in the municipality of Bergün Filisur, in the Swiss canton of Graubünden. It is located on the 1,000 mm (3 ft 3+3⁄8 in) metre gauge Albula line of the Rhaetian Railway. Hourly services operate on this section of the line.

Preda is a small village within the Swiss municipality of Bergün Filisur (until the end of 2017 Bergün/Bravuogn), district of Albula, Canton Graubünden (Grisons), in the East of Switzerland.The name Preda, like Prada, derives from the Latin pratum = meadow.Preda is located in the upper valley of the Albula Alps. It lies on the road over the Albula Pass at 1789 metres above sea level (a.s.l.) and at the north portal of the Albula Tunnel of the Rhaetian Railway. To reach Preda, while avoiding too steep ramps, the Rhaetian Railway needs passing several valleys over impressive viaducts and cross-cutting the mountain in several spiralling tunnels (Kehrtunnel in German). This allows the railway to overcome a difference in altitude of 416 metres from Bergün to Preda. The line runs from Chur or Davos to St. Moritz and ends at the route of the Glacier Express.

The Albula Tunnel is the centrepiece of the Albula Railway, which forms part of the Rhaetian Railway network, in the Canton of Graubünden, Switzerland. With its maximum elevation of 1,820 m (5,970 ft) above sea level, it is amongst the highest tunnels in the Alps, and has a mountain overlay of up to 950 m (3,120 ft). The tunnel has a length of 5,865 m (19,242 ft). It opened for traffic in 1903.The northern portal of the tunnel is at Preda, in Bergün, and the southern portal at Spinas, in the Bever valley. At a total length of 5,865 m (19,242 ft), the tunnel connects the Albula Valley with the Engadin Valley, and, in so doing, passes under the watershed between the Rhine and the Danube a few kilometres west of the Albula Pass. The tunnel serves both passenger and freight traffic. The Glacier Express passes through it daily. During the winter season, car transporter trains operating between Thusis and Samedan also used the tunnel until 2011. Due to the threat of rockfalls and general deterioration over time, it was planned for the original tunnel to have been renovated during the 2020s. But in 2010, the Rhaetian Railway announced that it had identified the construction of a second tunnel alongside the first as its preferred option, with one of several reasons being a relatively minor difference in cost. Costed at around CHF 244 million, construction commenced during 2014. In comparison to the original Albula Tunnel, the new bore is considerably larger due to newer operational and safety standards. The second tunnel is set to be opened to traffic in 2024, with completion of the project including refurbishment of the original tunnel by 2025. Once completed, around 15,000 trains are predicted to use the tunnel each year; it has been built to allow for a maximum speed of 120 km/h.

The Glacier Express (GEX) is a direct train connecting railway stations of the two major mountain resorts of Zermatt and St. Moritz via Andermatt in the central Swiss Alps. The train is not an "express" in the sense of being a high-speed train, but rather, in the sense that it provides a one-seat ride for an 8-hours-long end-to-end 291 km (181 mi) journey, and omits stops made by local trains. The Glacier Express is known as the slowest express train in the world. As St. Moritz and Zermatt are home to two well-known mountains, the Glacier Express is also said to travel from Matterhorn to Piz Bernina.The journey from Zermatt starts at the dead end of an Alpine valley, the Mattertal, just below the world-renowned Matterhorn at an elevation of 1,606 m (5,269 ft) before it descends to the huge valley of the Valais in Brig. It traverses the 291-kilometre-long (181 mi) journey through the center of the Swiss Alps, over 291 bridges, through 91 tunnels, such as the 15.4 km-long (9.6 mi) Furka Tunnel at an elevation of 1,500 m (4,900 ft) to circumvent the Furka Pass, makes an intermediate stop at Andermatt on a secluded high Alpine valley, just to traverse its highest point on the Oberalp Pass at 2,033 m (6,670 ft) in order to descend to its lowest point at Chur at 585 m (1,919 ft). From Chur, the capital of the canton of Graubünden, the GEX backtracks to higher altitudes again in order to reach the resort St. Moritz in a further valley to the south. Previously, before traversing the Albula Range by a tunnel at 1,800 metres (5,900 ft), in Filisur travelers can change to a connecting train to reach Davos to the east. Since 2017, the train is operated by the Glacier Express AG, a cooperation jointly owned by the former operators Matterhorn Gotthard Bahn (MGB) and Rhaetian Railway (RhB). For much of its journey, it also passes along and through the World Heritage Site known as the Rhaetian Railway in the Albula / Bernina Landscapes. The first Glacier Express started on 30 June 1930 at 07:30 in Zermatt. Initially, it was operated by three railway companies: the Visp-Zermatt-Bahn (VZ), the Furka Oberalp Bahn (FO), and the Rhätische Bahn (RhB). Since 2003, the train has been operated by Rhätische Bahn (RhB) and the Matterhorn Gotthard Bahn (MGB), which arose from a merger between the BVZ and the FO. Since 2017 the Glacier Express AG, owned by the two former operators, runs the train of the same name. The entire line is metre gauge (narrow gauge), with 23.9 kilometres (14.9 mi) using the rack-and-pinion system both for ascending steep grades and to control descent.

Piz Bial is a mountain of the Albula Alps, located in Graubünden, Switzerland. It is situated between the Val Mulix and the Val Bever. The closest locality is Preda, on the Albula Railway.

The normal route to the summit starts from the heights of St. Moritz and Samedan, on the southern side of the mountain.

Bergün/Bravuogn (German: Bergün, Romansh: , in the local Romansh dialect Brauégn) is a village and former municipality in the Albula Region in the canton of Graubünden in Switzerland. The double name (German/Romansh) has been the official name since 1943. On 1 January 2018 the former municipalities of Bergün/Bravuogn and Filisur merged into the new municipality of Bergün Filisur.

The Albula Railway Museum (German: Bahnmuseum Albula) is located at the Bergün/Bravuogn railway station of the Albula Railway of the Swiss Rhaetian Railway. The museum is in operation since 2012.The museum tells the history of the construction of the Albula Railway and shows many historical plans and artifacts. Topographic simulations and demonstrations of the tunneling methods are part of the multimedia displays. One section of the museum houses a miniature Albula Railway operating in O scale built by Bernhard Tarnutzer that includes buildings, viaducts, and tunnels from the 1950s and 1960s. The Rhaetian Railway Ge 6/6 I "crocodile" #407 has been placed at its entrance and can be used by visitors for a ride simulation.
