Switzerland’s popular Alpine tourist train derailed today in the Alps, killing one person and injuring 42 others on its spectacular journey between Zermatt and St. Moritz. Three carriages from the Glacier Express came off the track for unknown reasons shortly after 12pm near a viaduct in the Goms Valley. Eyewitnesses said one carriage had tipped over and two others remained upright. No deaths have been reported so far.
