The operator admitted the frightening lapse, which saw 30 people injured, during interviews with investigators, Ted Turpin from National Transportation Safety Board announced today. 'She did admit that she dozed off prior to entering the station, and she did not awake again until the train hit close to the end of the bumper,' Turpin said. Scroll down for video
