While the train was in motion, three of the teens went outside and climbed onto the roof. One of them came in contact with a stationary object and fell.
The other teens went back inside the moving train and called 9-1-1.
Emergency responders transported the 15-year-old boy to hospital where he remains in life-threatening condition, officials said.
In an update on Monday morning, police told Global News there was no further update on his medical condition.
