The Glacier Express is probably Switzerland's most scenic train journey. It's a year-round train service between Zermatt at the foot of the Matterhorn and St Moritz in the Engadin skiing area.
Billed as Europe's slowest express, its a narrow-gauge train which takes 7½ hours to cover just over 290 km (180 miles), at an average of around 24 mph.
There is just one daily Glacier Express service in winter, but several daily trains in summer, although regular (usually hourly) local trains also operate over all sections of the Glacier Express's route.
