The boy, who has not been identified, was selling candy with his 11-year-old brother and a 26-year-old man, WCAU reported.
"He dropped all his candy all over the place inside the train, as he picked the candy up he went through the doors to go through the next train," Douglas Spencer told WPVI. "There were people crying, people that wanted to help him, but there wasn't much they could do besides jump down."
The train operator stopped the train when he learned of the incident.
The Southeastern Pennsylvania Transportation Authority is investigating.
