An unidentified person was struck by an Amtrak train Thursday afternoon in Delaware County, causing a halt in service on SEPTA's Wilmington-Newark Line, officials said.

About 3:35 p.m., Acela Express train 2121 heading south hit the person about a half mile from the Norwood Station. There was no immediate word on the condition of the person who was struck.

None of the 206 passengers were hurt, but the train was stopped for the police investigation. Other Amtrak trains were getting through the area because two of four tracks were still open, an Amtrak spokesman said.

Service on the Wilmington-Newark line resumed shortly before 6 p.m.
