The man was passed out on the tracks of the New York subway in Brooklyn
Liliana Vicente captured the footage on her mobile phone as she was waiting for her train in Brooklyn.
She can be heard shouting: "Sir?! Sir, please wake up!" from the platform.
As she screams and shouts, trying to get his attention, other commuters come to help.
As the commuters see a train in the distance hurtling towards the station they manage to rush to the emergency button which stops the Manhattan-bound train before it enters the station.
Vicente pushed the emergency button to stop the train
In the video Vicente is heard saying "My God. "Thank God the train has stopped."
The group climb down a service ladder to reach the man and pull him to safety on the platform.
Speaking to NCB, Vicente said: "A lady grabbed the guy from the left, and a guy, the guy from the right and me from the bottom."
A few minutes later firefighters attended the scene and the man wakes up.
It is unclear how the man got onto the tracks or if he is injured.
He was taken to Kings County Hospital and is said to be in a serious condition.
The video then shows the train pulling into the station, and all the good Samaritans board the subway and continue on with their daily lives.
