Woman rescued from subway tracks in Madrid

Too often, these stories end tragically. But thanks to an off-duty police officer's quick thinking, a woman who fainted onto the tracks of the Madrid, Spain, subway system was carried to safety seconds before the train arrived.

Spanish police released video surveillance that capture the incident.

The officer, identified only as 38-year-old Ruben, came to the 52-year-old woman's rescue after she collapsed onto the tracks at the Marques de Vadilla station in southwestern Madrid.

Bystanders tried to alert the train driver as Ruben jumped over the rails and pulled the woman to the opposite side of the tracks before the train approached.

An emergency service team and a doctor evaluated the woman at the scene. She was treated for minor head injuries and made a full recovery.
