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 eight - hours - long journey . 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 . </P> <P> The journey from Zermatt starts at the dead end of a Alpine valley, the Mattertal, just below the world - renown 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 . </P>
