Accident on Spanish metro

A 52-year-old woman had a lucky escape on Monday after falling onto train tracks in Spain.
Police think the woman fainted whilst she was waiting on the platform.
She was rescued by an off-duty police officer who climbed onto the tracks to reach her.
Climbing onto the tracks is very dangerous because a lot of railways have electric rails which can kill you if you touch them.
