Running across a level crossing in front of an oncoming train is dangerous - doing it in front of two is just crazy.
But that's what one man did at Corrimal station - and it was all caught on video.
In September the camera caught the man approaching the crossing heading east.
He's walking on the road because the pedestrian gates on both sides of the crossing are closed - and the boom gates are down.
He is just strolling along, until he looks to his left and sees something that forces him to run across two sets of tracks.
The man only just makes it across to the other side of the crossing when a large freight train headed north barrels through the level crossing.
But then another train comes into view - a passenger train heading south and both pass each other on the crossing.
The man saw not one, but two, trains coming down the tracks from opposite directions and still figured it was a good idea to dart across their path.
Had he tripped on one of the rails and fallen, it's likely at least one of those trains would have hit him.
It would mean the man would have been dead, and the train driver would have to live with the trauma of having hit and killed someone.
It follows previous incidents, such as the Dapto schoolboy who gave a train driver the finger as he ran over rails last year.
A year earlier, Bellambi high school students were caught dashing over the lines in front of a freight train, after two girls seem to place items on the track.
In 2015, TrainLink NSW released footage of three men racing across the crossing at Woonona, the last less than a second in front of the train.
The South Coast line has historically had a problem with people trespassing on rail lines.
NSW TrainLink Chief Executive Pete Allaway said they had released the video during Rail Safety Week to highlight the dangers of disobeying the red lights and boom gates at level crossings.
Mr Allaway said some passenger trains weigh more than 400 tonnes.
"If you could see what a train driver sees and how long it takes for a train to make an emergency stop, you would think again before stepping out onto a level crossing or in any part of the rail corridor," Mr Allaway said.
"Some passenger trains and often freight trains come through platforms and level crossings at speeds and can take hundreds of metres to stop."
