Amtrak has reopened its tracks outside Baltimore after a train hit and killed a teenager on her way to school, but there are still delays up to two hours along the Northeast corridor.

Amtrak spokeswoman Karina Romero says some midday trains were canceled and passengers were rebooked. She says the goal is to eliminate the delays in time for the evening rush hour.

Some Maryland commuter trains were also canceled after the accident, which happened around 9 a.m.

Baltimore County police identified the victim Tuesday afternoon as 14-year-old Ann Marie Stickle of Middle River. Police say she was walking southbound along the tracks with a friend on the way to school, and the train hit her from behind, killing her. The friend was not injured.
