PITTSBURGH — Authorities say a woman was killed and a man injured while hopping a train in Pittsburgh.

Pittsburgh public safety officials say emergency responders were called to the Norfolk Southern train tracks on the city’s South Side at about 2:30 a.m. Sunday.

They found that a man and woman had been hopping a train when the woman fell and was dragged under the train.

She was pronounced dead at the scene and later identified by the Allegheny County coroner’s office as 21-year-old Lindsey Marie Michaels. The man also fell and injured his ankle.

Norfolk Southern spokesman Jon Glass told the Pittsburgh Tribune-Review that a freight train carrying coal was traveling on Norfolk Southern’s Mon line at the time. He said the train crew wasn’t aware anyone had been hit.
