The driver of 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, who was standing on the platform at North Station when she saw the woman tumble.
Ms Lewis, who saw passengers on the platform frantically waving their arms, immediately tugged the emergency brake.
The woman, whose name was not made public, suffered cuts and bruises and was taken to a hospital for checks.
She told police she had been drinking.
