The Gornergrat Railway (; GGB) is a mountain rack railway, located in the Swiss canton of Valais. It links the resort village of Zermatt, situated at above mean sea level, to the summit of the Gornergrat. The Gornergrat railway station is situated at an altitude of , which makes the Gornergrat Railway the second highest railway in Europe after the Jungfrau, and the highest open-air railway of the continent. The line opened in 1898, and was the first electric rack railway to be built in Switzerland. The Gornergrat is a starting point for many hikes, as it lies surrounded by 29 peaks rising above in the Alps and several glaciers, including the Gorner Glacier (which is billed as the second longest glacier in the Alps). At the end of the line on Gornergrat, the Matterhorn is visible on a clear day. It is also a popular skiing area. The Gornergrat Railway Ltd (Gornergrat Bahn AG) is a wholly owned subsidiary of BVZ Holdings AG, who are also the majority owners of the Matterhorn Gotthard Verkehrs AG, the company that operates the Matterhorn Gotthard Bahn (MGB), with which the GGB connects in Zermatt. History Work on the railway started in 1896, five years after the Visp-Zermatt-Bahn had linked Zermatt to Visp and the Rhone Valley. The line opened on August 20, 1898, and was electrified from the start. Initially it only operated in summer, but year-round operation was extended to the lower section of the line in 1929, and to the summit in 1941. The Gornegrat Railway was the highest railway in Europe until the opening of the Jungfrau Railway in 1912. The upper terminal was remodelled in 2004. Operation Route There are several passenger stops on the line: There are also freight-only stations at Ladegleis Findelbach, which is on a short branch from the passenger station at Findelbach, and at Riffelboden, which is situated between Riffelalp and Riffelberg passenger stations. Infrastructure The line is in length, including of double track, and traverses an altitude difference of . It is built to metre gauge () and uses the Abt rack system throughout. It is one of four lines in the world using three-phase electric power, requiring two overhead conductors, with the track forming the third conductor. There is a non-powered connection with the metre gauge Matterhorn Gotthard Bahn at Zermatt to allow transfer of freight and delivery of rolling stock. Rolling
