On Friday night, Boston train conductor Charice Lewis saved a woman’s life when the woman–who was under the influence of alcohol–fell off of the station’s platform and on to the train tracks.

As frantic commuters waved at 27-year-old Lewis–who could not see the woman on the tracks–to stop the train, she quickly staged an emergency stop and “prayed for the best.”

The woman on the tracks walked away unharmed and Lewis walked away a hero.
