This is the heart-stopping moment a young boy fell between a train and the platform seconds before it was due to set off.
In the shocking video, the two-year-old boy can be seen plunging down the gap with ease.
His terrified grandparents wave and scream in order to stop the train that was setting off.
It was caught on CCTV at Australia's Cronulla station and has been released so that others can be warned about the danger involved in small children boarding trains.
Grandfather John Brewster told 9news.com.au : "It took years off my life. I'll never forget it.
"It happened that bloody quick. We were running because it was raining, we'd had an ice-cream then we were taking the train because Ayden (his grandson) loves trains.

"He could've hit his chin on the train and broken his neck and this would be very different," he added.
Over 220 children fell between trains and platforms on the Sydney trains network last year alone.

Transport minister Andrew Constance has urged for parents to be more vigilant in similar situations as it 'will only be a matter of time before a serious accident'.
Many cities in Asia and Europe have screen doors at their train stations to stop people from falling onto platforms.
The technology will feature on Sydney's new rail system which is currently under construction.
It's unknown whether Cronulla station will receive the same treatment.

"The rise in the number of injuries suffered by kids slipping through the gap on station platforms is a concern, and I worry that unless we get the message across that parents need to be more vigilant, it will only be a matter of time before we see a serious accident," Constance told the Daily Telegraph.
"Our message is don't rush, hold your child's hand and please take care when you are at a busy station.
"We've got school holidays and the Easter Show upon us, and with packed trains and excited kids it's more important than ever to be keeping an eye on children."
Sydney Trains boss Howard Collins added: "If you're using a pram, keep a firm hold and always apply the brakes at the station and on the train."
