Terrifying footage has emerged showing commuters taking part in risky stunts across Sydney's train network.
CCTV footage from train stations across the city shows people running in front of moving trains, riding on the back of carriages and sliding down railings.
The life-threatening behaviour is being slammed by transport authorities who are urging commuters to stop participating in such risky behavior.

Footage was released as part of Rail Safety Week alongside figures revealing the extent of risk taking as well as mishaps and accidents across the train network.
New South Wales Minister for Transport Andrew Constance said the footage should act as a sobering reminder for commuters.
'It's really concerning to see people getting hurt and risking their lives to chase social media likes. We've seen 2,689 incidents of trespassing in the last 12 months, many of them reckless acts for selfie stunts,' Mr Constance said.
'Some of these incidents such as people sliding down handrails and spraining their ankles, or falling over while looking at their phones are easily avoided with just a little more common sense.'

In another video a passenger runs across the tracks to get to the opposite platform to catch their train.

Not all the behaviour caught on camera involves taking risk, with a number of accidents also on display to warn passengers to pay more attention.
This includes a number of people falling onto the tracks, down stairs or running into a train carriage after the door had already slammed shut.
New South wales Transport said there was 1,925 incidents of slips, trips and falls around the rail network in the past 12 months.
Sydney Trains Acting Chief Executive Suzanne Holden said people don't realise how dangerous train stations can be.
'It is easy to forget how dangerous trains and stations can be if you are distracted or in a hurry, trains travel at speeds of more than 100km/h, they are surprisingly quiet and take a significant distance to stop,' she said.
