This ain’t no video game — people really are risking life and limb to jump around on top of trains.

“Train surfing” is when people ride on a train anywhere that isn’t inside the car (you know, where you’re supposed to be!). While this is sometimes done in poorer countries to pack more people onto the train, a few opt to hop from train to train, turning the train-surfing experience into an adrenaline-filled sport.

This is, needless to say, incredibly dangerous, but the videos from the people doing these insane stunts really can’t be beat.
