The driver of a Boston subway train that stopped just before hitting a woman who had fallen onto the tracks has been hailed as a hero.
Charice Lewis got a radio call from fellow subway employee Jacqueline Osorio when she saw the woman, who had been drinking, tumble over.
Ms Lewis immediately tugged the emergency brake which stopped in time.
"As I'm approaching, the lady pops her head up, and I'm like 'Oh my God, someone's in the pit'. So I just threw it in emergency, exactly what I'm supposed to do. And it stopped just in time not to hurt her," said Ms Lewis.
