Probably The Tease Of Teases Part 3 (Backside View)
Little guy wanted to take a picture in the middle of railway bridge. Unfortunately, he touched the high-voltage power line (2:20) and fell to the ground on the rails. With the camera still going, his friend with the camera raced to the ground as quickly as he could. At 3:30, we hear the train approaching and hit the body, and the screams of the young boy with the camera as he sees his friend hit by the train. The train driver called an ambulance, but it was too late, there was nothing anybody could do to save the boy.
