The Gornergrat Railway (German: Gornergrat Bahn; GGB) is a mountain rack railway, located in the Swiss canton of Valais. It links the resort village of Zermatt, situated at 1,604 m (5,262 ft) above mean sea level, to the summit of the Gornergrat. The Gornergrat railway station is situated at an altitude of 3,089 m (10,135 ft), 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 4,000 m (13,123 ft) 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.
