CCTV footage reveals the man hunched over before swaying onto the tracks at Rhode station on Wednesday afternoon.
Commuters reacted quickly as they waved frantically towards an oncoming train.
Watch the terrifying moment he collapsed and brave onlookers jumped down to help
Within seconds brave onlookers jumped onto the tracks to his aid, the driver of the approaching train saw the commotion and stopped.
"It's a heart-stopping moment for everyone here," chief executive of Sydney Trains Howard Collins told 7News.
The transport Minister Andrew Constance acknowledged the 'brave' actions of the commuters however advised to first notify professional staff of any dangerous incidents.
"It is a danger situation, we could've seen a lot of people killed" he said.
A train worker intervened to control the crowd, directing them to stay behind the yellow line as part of basic safety protocol.
"Obviously you make that reaction to try and save someone's life" Collins told 7 News.
"You've got to consider the other things around you which could put you at risk, I'd hate to think if another train came the other way there could've been more serious incidents" he continued.
Mr Collins revealed around 50 commuters have fallen ill so far this year which in turn has delayed around 260 peak-time services.
Sydney Trains advised anyone feeling unwell at a station to contact staff immediately.
