The accident, near the town of Goppenstein, occurred as the region is under its second-highest avalanche warning, a level four out of five.

A regional train has derailed in southern Switzerland, injuring five people, police said, as the risk of avalanches in the region has reached its second-highest level.

The accident on Monday near the town of Goppenstein occurred amid heavy snow and at an altitude of 1,216 metres (4,000 feet), according to the AFP news agency.

“According to initial findings, an avalanche may have crossed the tracks shortly before the train passed,” police said, adding that the public prosecutor’s office has opened an investigation.

“Five people were injured. One of them was taken to hospital,” police added.

The train accident follows a series of deadly avalanches across the Alps in recent days involving skiers.

On Friday, three skiers were killed after being swept away by an avalanche in the upmarket French Alpine resort of Val d’Isere.

Cedric Bonnevie, who oversees the resort’s pistes, said one of the victims was a French national while the others were foreign citizens.

He said one victim appeared to have been caught in the avalanche high on the mountain slope, while the other two were part of a group of five, including a professional guide, lower on the mountain face and did not see the avalanche approaching.

In Italy, rescuers said last week that a record 13 backcountry skiers, climbers and hikers had died in the mountains over the previous seven days, including 10 in avalanches triggered by an exceptionally unstable snowpack.

Fresh snowfall during recent storms, combined with windswept snow sitting on weak internal layers, has created especially dangerous conditions across the Alpine arc bordering France, Switzerland, Austria and Italy, Italy’s Alpine Rescue said.

“Under such conditions, the passage of a single skier, or natural overloading from the weight of snow, can be sufficient to trigger an avalanche,” Federico Catania, Alpine Rescue’s spokesperson, said.

The avalanche deaths have occurred on ungroomed mountain slopes, away from the well-maintained and monitored Winter Olympic sites in Lombardy near the Swiss border, Cortina d’Ampezzo in Veneto, and the cross-country skiing venues in Val di Fiemme, within the autonomous province of Trentino.
