Sickening video has captured the moment two train-surfing teenagers in Austria slammed into a train station bridge — leaving the blood-spattered boys critically injured.
The horror unfolded as the Czech youngsters, ages 17 and 18, were riding on top of a train car near Schoenbrunn Station in Vienna on Tuesday, local authorities said.
The stomach-churning clip shows the teens, who were being filmed by two friends, initially ducking down and lying flat on their stomachs as the train tore through a tunnel.
Soon after emerging on the other side, the boys could be seen rising to their knees and brazenly raising their arms against the wind.
The teens then jumped to their feet and attempted to run toward the back of the train as it approached the station and an overhead pedestrian bridge, according to the footage.
Seconds later, one the boys can be heard shouting, “Down, down, down” before a loud thud rings out and onlookers scream in horror.
The video shows two of the boys lying on their backs atop the carriage — with blood streaming from one of their faces — as the train pulls to a stop at the platform.
First responders rushed to the scene after one of the less injured boys activated an emergency stop at the station. The two severely injured teens were treated on the platform before being rushed to a nearby hospital, where one of them was placed on life support.
“Both were critically injured,” the Vienna Police Department said in a statement.
“The two other people involved, a 13-year-old and a 16-year-old Austrian citizen, initially ran away, but returned to the scene of the incident shortly afterwards.”
The 16-year-old suffered minor injuries in the ordeal, while the youngest was unharmed. The train driver, meanwhile, was receiving psychological counselling, police added.
A spokesperson for Vienna’s transit network company, Wiener Linien, immediately slammed the saga, urging others not to engage in similar behavior.
“No selfie or TikTok video in the world can be worth that,” said the spokesperson, Carina Novy.
The incident follows a spate of deadly subway-surfing ordeals in New York — including one in Queens on Sunday that left a teen girl dead and her friend critically injured.
The girl was the sixth person to die from the reckless stunt in the Big Apple this year alone.
