A 2-year-old girl escaped with some minor bumps and bruises after her stroller rolled onto the subway tracks in Queens, reports the Daily News. Her mother and a maintenance worker jumped down and pulled her to safety before a train arrived, say police. The drama began yesterday when the mother let go of the stroller to throw out some trash while on the subway platform, and the stroller then rolled down onto the tracks. She and a worker identified only as Diane jumped down after it, with the mother sustaining a sprained ankle. The worker led them both to safety. As a precaution, transportation authority workers used flashlights to stop the next train en route, reports CBS New York.
