A 14-month-old baby had a lucky escape after the pram she was in rolled onto the tracks at a Philadelphia train station.
CCTV footage showed the mother jumping onto the tracks and saving her daughter as people at the station ran over to help.
One bystander used an emergency call box and warned controllers of the situation.
Officials then managed to tell an approaching train, that was only one minute away, to stop before entering the station.
The child suffered a cut to her forehead but was otherwise in good condition, according to NBC News.
