The Glacier Express (GEX) is an "express" train connecting railway stations of the two major mountain resorts of Zermatt and St. Moritz via Andermatt in the central Swiss Alps. 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 8-hours-long end-to-end journey, and omits stops made by local trains. 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.
