PLUM, Pa. — Authorities in western Pennsylvania say the death of a teenage girl struck by a train as she was walking on railroad tracks near Pittsburgh has been ruled accidental.

Police in Allegheny County said 17-year-old Ciara Hasselman was walking on Bessemer Lake Erie Railroad tracks in Plum near the Oakmont Country Club pedestrian bridges.

Superintendent James Morton said the girl didn’t move from the tracks “despite numerous signals from the train” and was struck shortly after 3 p.m. Saturday. She was pronounced dead just before 6 p.m. Saturday at Forbes Regional Hospital.

The county medical examiner’s office said Sunday that she died of blunt-impact injuries and ruled the death accidental.

Patrick Waldron of Canadian National Railway said the southbound train consisted of only two cars and was halted while police investigated.
