The Arth–Rigi railway line is a Swiss standard gauge rack railway that runs from Arth-Goldau RB to Rigi. It was built by the eponymous Arth-Rigi-Bahn (lit. 'Arth-Rigi Railways') between 1873–1875 and operated by that company until its merger with the Vitznau-Rigi-Bahn in 1992 to form Rigi Railways.

When the people of Art, canton of Schwyz, heard that a railway to Rigi was to be built from the Lucerne side, they sought and received a concession in 1870 from the Cantonal Council of Schwyz to build lines on the Schwyz route between Staffelhöhe (Rigi Staffel) and Rigi Kulm and between Arth, Oberarth and Kulm. They commissioned the two engineers, Olivier Zschokke and Niklaus Riggenbach, to build the line. The Arter Aktiengesellschaft (Art Ltd.) immediately started building the line from Staffelhöhe to Rigi Kulm (1752 m above sea level). The Vitznau–Rigi Railway company line connected its line with this line in the summer of 1873 and it had to pay fees for the use of the Staffelhöhe–Rigi Kulm section until the merger of the two companies in 1992.

Construction of the line from Goldau (518 m asl) – those days not more than a hamlet – to Staffel via Kräbel and Klösterli (1315 m asl) started in 1873 and work on the Art-Ober Art-Goldau section started in 1874. On 4 June 1875, the Art-Rigi Railway (Art-Rigi-Bahn) was able to commence operations along the whole line. Although it had lost the race against the Vitznau–Rigi Railway, the line had glorious views and more luxurious coaches. The mountain railway started operating in winter between Goldau and Rigi-Kulm in 1928.

Originally, the standard gauge line began in Art on the shores of Lake Zug.^[2] This ran as an adhesion railway to the Goldau station. It was separated from the rack railway in 1881 and run separately as tram, but a connecting track remained. This branch was closed in 1959 and the tracks were dismantled.

Initially, most passengers travelled by boat over Lake Zug. From 1882, the platforms of the ARB were placed parallel to those of the Gotthard Railway on its station forecourt.^[2] As the latter, however, claimed more and more space for its rail tracks, the ARB built its notable wrought iron high-level platform over the Gotthard Railway’s tracks in 1897. Now, the majority of the ARB's passengers arrived by train.^[2] From 2011 to 2013, a new, two-track station layout was built before the high-level platform and the heritage-listed platform was rebuilt as an entrance hall. Originally, the opening of a new station parallel to the SBB route had been considered, but this had to be discarded because the SBB needed more space in this area due to the building of the Gotthard Base Tunnel.

On 1 May 1907, the ARB was the first standard-gauge rack railway in the world converted to electric traction. The bottom station of the cable car to Rigi Scheidegg (1568 above sea level) is in Kräbel. Earlier the mountain had also been connected by the metre-gauge Rigi–Scheidegg Railway (Rigi-Kaltbad-Scheidegg-Bahn, RSB), but this was dismantled in 1942.

On 3 June 2000, the Arth–Rigi Railway celebrated its 125th anniversary with a steam festival.

During the night of 19–20 January 2014, the high-level platform in Arth-Goldau station was raised by two metres so that it could be reconstructed on site.^[3] After this renovation, it was lowered by 1.3 m. In July 2017, the new station hall for the high-level platform went into operation and the provisional platforms were dismantled. In the same year, the rectifier in Klösterli was replaced by a more modern, higher current device.
