The incident happened around 6:50 p.m. Wednesday in the area of 46th and Market streets in West Philadelphia.
SEPTA officials say the girls between the ages of 13 and 16 had gotten into a fight and the victim ran to their station seeking help.
That's when the teenage girls followed her, pinned her down and assaulted the 16-year-old victim.
Police say one of the teens pulled out a can of hair spray and a lighter. She allegedly lights the hair spray which catches fire to the victim's hair and also burns her neck.
