reach the rolling baby carriage, frantically waving to alert the train conductor. but it's too late. the stroller drops onto the tracks right into the path of the arriving train. in an instant, the boy and stroller are gone. on the train station surveillance footage, the mother can be seen lunging for the rolling stroller and nearly jumping from the platform to save her son. stunned onlookers watch helplessly as the train slams into the carriage. the mother screams in anguish. fearing the worst, she races toward the front of the stopped train. now 100 feet further along the tracks. remarkably, the boy is found under the train, crying and only slightly injured. because of the way he falls, he is protected by the stroller and survives with only minor cuts and bruises. it's a happy ending to one frightening ordeal.
