Moment a railway station worker saves a suicidal woman by dragging her back

Surveillance footage from the high-speed railway station shows the woman running to the edge of the platform.

What the video doesn't show is that a bullet train is fast approaching the platform. 

A quick thinking railway worker sees the woman running and rushes over to grab her. 

Just as she is about to get on the track, the man manages to pull her back knocking his head on the ground. 

On the floor, he manages to pull her back further and out of the train's way. 

The railway worker suffered an injury to his head during the rescue attempt.
