Woman falls onto tracks of approaching train after man faints on her

CCTV shows commuters wave their arms to alert train driver

A woman narrowly escaped death after being knocked onto the line in front of an approaching subway train by a fainting man.

CCTV footage showed the woman being knocked unconscious as she fell off the metro platform in Buenos Aires, Argentina.

In the video, a man can be seen fainting towards the woman, pushing her onto the tracks as the train approaches.

Commuters rush to help and wave their arms at the train driver to get them to brake in time.

The train manages to stop just metres away from the woman.

Other subway users then jump on to the tracks to pull her to her feet and get her back on to the platform.

Meanwhile, the man who fainted was also helped to his feet.

The incident took place around 11am local time on Tuesday morning, on line D at the Pueyrredon Metro Station.
