frantic rescue by policeman and fellow emerges after woman faints and falls onto a train line

Heart-stopping footage of an off-duty policeman rescuing a woman who fainted and tumbled onto the tracks at a Spanish rail station has emerged. Spanish police have released a clip of the officer bravely leaping onto the rails and rushing to the stricken woman's aid despite a train being due to arrive just seconds after her fall. The unnamed 52-year-old woman somersaulted head first onto the tracks after collapsing while waiting for a Madrid Metro train at the city's Marques de Vadilla station on Monday afternoon. Some commuters rush to the platform edge desperate to help the woman who is seen lying prone on the rails, while others run off to find help. But, without a seconds thought for his own safety, the unnamed 39-year-old policeman, who was stood at the other end of the platform, sprang into action. According to police he had heard the woman's body hit the tracks. He is seen leaping down onto the tracks close to the entrance of the metro tunnel and sprinting along the rails. Terrifyingly, just as he reaches the woman the lights of an approaching train begin to emerge from the tunnel.
