Family and friends of the two 15 and 16-year-old Interboro High School sophomores, gathered at the accident site at 501 Welcome Avenue in Norwood, and at the Norwood Police station.
The identity of the girls is yet to be released. It is still unclear why the teens were standing on the tracks. According to Norwood police, a third girl was at the scene when the girls were struck. She is cooperating with police.
A ticket agent at SEPTA's Norwood station said he saw the girls standing on the southbound side shortly before the accident, reports the Inquirer. Bruce Wright, who didn't see the train hit the girls, said that one of the teens was on a cell phone.
