Once again, high speed impact robs a man of his clothes in death. In this case it robbed him of his legs as well.
There’s no info on this video but more likely than not, the guy was too impatient to wait for the train and tried to beat it at the level crossing. It’s a good demonstration of how much force a train has and how long it takes to stop because right when you think the filmers have long passed all the bits, bam! There’s another chunk of flesh (leg?).
Somebody claimed this came from the Netherlands but I’m skeptical because of the English cry of “holy shit!” although it could be a tourist.
