A heart-stopping moment unfolded in the Swiss Alps as an avalanche cascaded down a mountainside, colliding with a train. The dramatic scene was captured by a quick-thinking tourist.

The incident occurred on February 17 near Zermatt, a renowned ski destination in Switzerland’s Valais region.

Kirsten Osborne, an Australian residing in the United Kingdom, was aboard the train with other passengers when the avalanche hit, according to Storyful.

Osborne managed to capture the intense moment as a towering wall of snow surged down the mountain, heading straight for the train.

A child’s voice can be heard repeatedly saying “uh-oh!” in the footage as the formidable wave of snow approaches with alarming speed.

Within seconds, the train is engulfed in a thick white cloud as the avalanche crashes into it and covers the window in snow, causing the train to shake.

Osborne described how passengers were left stranded for around two hours following the impact. 

“We were stuck for two hours before the rescue and provided bus transport to safety,” she said.

Despite the terrifying scenes, no injuries were reported.

Matterhorn Gotthard Bahn, the rail company that operates the route, has since confirmed that all passengers were safely evacuated in coordination with emergency services.

“At around 11 a.m. on Tuesday morning, another avalanche occurred between Täsch and Randa,” the company said in a statement.

“A regional MGBahn train was struck by a resulting powder-snow avalanche. No one was injured. Passengers were evacuated in cooperation with the emergency services.

“As a precaution, and in consultation with external local natural hazard specialists, MGBahn has decided to suspend operations on the St. Niklaus–Täsch route until further notice,” the company said.

MGBahn also confirmed it was in “close contact with specialists and experts to assess the situation along the entire route network between Disentis (GR) and Zermatt (VS).”

The incident happened amid dangerous winter conditions in the Swiss Alps, where heavy snowfall has impacted the tourist season.

The avalanche strike on the train came just a day after another rail incident near the town of Goppenstein, where a train derailed, injuring five people.

Local reports indicated that an avalanche may have been a possible cause of that derailment, although investigations are ongoing.

Large areas of the western Alps have been affected this season by avalanche risks, according to The Times.
