The unknown man is seen lying lengthways between the tracks while an approaching train terrifyingly thunders over the top of him.
The 56-second clip was uploaded on YouTube where it attracted 270,000 hits before being removed, reports the Daily Mirror.
It is unclear whether the video was shot in the UK but Network Rail have branded the stunt as "stupidity in the extreme".
A Network Rail spokesman said: "It doesn't bear thinking about what would have happened if the turbulence created had swept the man's coat up into the underside of the train.
"Not only that but think about the effect on the train driver who believes he has just killed somebody.
"Nobody who has any regard for their own safety or the feelings of others should attempt a stunt like this."
