It occurred days after another man was pushed to his death in front of an oncoming train. No one seemingly came to his aid.
Voice of America journalist Margaret Besheer says it happened Thursday night at Bowling Green station in Lower Manhattan.
She saw a disoriented man sitting between the rails. People on the platform were screaming "a train is coming!" Next, she saw another man on the tracks helping the victim to his feet.
The train stopped before entering the station. Cheers erupted as the two men pulled themselves up to the platform.
Authorities didn't have details of the incident Friday. The New York Post reported it first.
