One of Switzerland's best-known tourist trains, the Glacier Express, derailed on Friday at the peak of the holiday season, killing one and leaving about 40 injured, Reuters cited a railway official as saying. The Swiss news agency ATS reported that most of the injured were Japanese tourists. Six of them were in a serious condition. The Glacier Express is a major Swiss attraction, as it travels from St. Moritz to Zermatt through some spectacular Alpine views. Swiss media said the accident took place between the skiing resort of Lax and the village of Fiesch, near the Swiss-Italian border. Photographs posted on Swiss media websites showed at least three carriages toppled over. Fatal train accidents are rare in Switzerland.
