That’s when Stanton was riding the G train in Brooklyn when it suddenly came to an abrupt stop.

After being held in the train for 20 minutes, Stanton said they pulled into the Hoyt-Schermerhorn station. The delay was apparently caused after a woman tumbled onto the tracks as another train was arriving.

Stanton was told by another passenger that the woman had a seizure and fell.

Stanton snapped a shot of the photo the other passenger took, which shows just how close the train came to hitting the woman.

The photo has gone viral online.

The incident comes as the Tranport Workers Union has launched a campaign to get trains to slow down before they enter the station. The campaign comes in the wake of two recent subway track deaths. The MTA has called that campaign a bid by the TWU to draw attention to their contract negotiations.
