The Amtrak train was headed to New York City from Philadelphia, and was carrying close to 200 people.
Officials are unsure what led to the accident, but Amtrak officials shut down two of the four tracks in that area and reduced speeds on the others.
Passengers were transferred to another train before continuing on to New York. No one on the train was injured.
The victim remains unidentified. An investigation is in progress.
Service was back to normal by early evening.
