The driver of a Boston subway train made an emergency stop only inches short of a woman who had fallen onto the tracks and was stumbling and flailing around.

Charice Lewis, the driver, had been alerted only moments before by a fellow MBTA employee who radioed her from the platform.

The hair-raising incident, with fellow passengers waving frantically on the platform as Lewis pulled the emergency brake, was caught on security cameras.

The woman, whose name was not made public, suffered some scrapes and was taken to a hospital for evaluation after the incident last Friday. She told authorities she had been drinking.
