The Rhaetian Railway (German: Rhätische Bahn; Italian: Ferrovia retica; Romansh: Viafier retica), abbreviated RhB, is a Swiss transport company that owns the largest network of all private railway operators in Switzerland.

Inaugurated in 1888 and expanded from 1896 onwards in various sections, the RhB network is located almost entirely within Grisons, with one station across the Italian border at Tirano.

In 2008, the RhB section from the Albula/Bernina area (the part from Thusis to Tirano, including St. Moritz) was added to the list of UNESCO World Heritage Sites.

The establishment of the Rhaetian Railway traces back to Dutch Willem Jan Holsboer, who owned a hotel in Davos.

[5] Holsboer founded the Landquart-Davos AG to begin construction of a standard-gauge line, but the mountainous terrain lacked sufficient space.

[5] In 1895, Holsboer changed his company's name to the Rhaetian Railway (Rhätische Bahn) to reflect his plans for network expansion.

[5] During the years 1907 to 1910, the Rhaetian Railway, in collaboration with the federal and cantonal governments, undertook a large-scale expansion of its network.

In 2022, to celebrate the 175th anniversary of Switzerland's first railway, the Rhaetische Bahn, supported by Swiss train-builder Stadler, came together to run the world's longest-ever passenger train, composed of 100 cars stretching almost two kilometres long.

Landquart railway station in Graubünden is the starting point of the Rhaetian Railway, historically as part of the Landquart-Davos line, operationally as the company's main workshop, and topologically as the 0 kilometre point of the company's core network.

Along the way, it crosses the river three times and passes by the award-winning Sunniberg Bridge, the centerpiece of the Klosters bypass road.

The connecting line from Davos Platz to the Albula Railway at Filisur passes through wild gorges, and is technically very interesting, not only due to its famous Wiesen Viaduct.

[editorializing] The Davos–Filisur line is 19 km (12 mi) long, runs through 14 tunnels extending a total of 4,200 m (13,780 ft) in length, and crosses 28 bridges.

As a result, it was announced that an inquiry would decide between two options for action: a comprehensive renewal of the existing tunnel, or the construction of a new bore to modern standards.

The Reichenau to Disentis/Mustér line links the rest of the Rhaetian Railway network with the Matterhorn Gotthard Bahn.

In contrast with the accompanying road, which rises about 500 m (1,600 ft) towards Flims and Laax, the railway to Disentis/Mustér runs slowly up the narrow "Ruinaulta gorge".

Since the opening of the Engadin line, Pontresina has been a dual system station, as the Bernina Railway operates on 1,000 V DC.

The 25.68-kilometre (15.96 mi) railway line from Chur to Arosa is known as the Arosabahn (or Arosa-Bahn), and is often abbreviated as "ChA" (Chur-Arosa).

A 5 km (3.1 mi) tunnel through the Mittenberg had been planned as an alternative route for the lower section of the line, avoiding running through the centre of Chur.

[10] The RhB operates regular InterRegio (IR), RegioExpress (RE), and Regio (R) services, as well as the Chur S-Bahn.

Apart from the normal passenger coaches and the panoramic coaches used for the branded Bernina Express tourist services, the railway attaches to the back of trains, according to need: The RhB is 51.3% owned by the Cantonal government of Graubünden, 43.1% by the Swiss Confederation, 4.6% by private shareholders and 1% by a collection of local communities.

Not only was the Rhaetian Railway featured in the film, but several landmarks were also included: the Landwasser Viaduct and a 1912 Mittelthurgau-Bahn Ec 3/5 Class 2-6-2 tank locomotive No.

The locomotive's fictitious number being used in the movie was 2747, as this was a reference to the address of the Fox Animation Studios on East Camelback Road in Phoenix, Arizona.
