The Swiss railway system is famous for its reliability and punctuality. Being one of the densest railway grids in the world, millions of commuters rely on trains. Disruptions due to snow used to be very rare. On Sunday evening, the 400 Passengers of a local train between Sion and Lausanne had to be evacuated by rescue teams, after they were stuck in the train for 5 hours.
This was near lake Geneva at c. 400 meters altitude in a densely populated region, not on a high alpine route.
Rescue teams had to connect the railway cars to an emergency power source to provide heating. As the nearby roads were also blocked be snow, 200 passengers were accommodated in an emercency sheltered overnight in a school in Bex.
