Amtrak says service on Northeast Corridor between New York and Philadelphia is mostly back to normal after it was disrupted by a fatal accident on the tracks in central New Jersey.

But officials warn that some residual delays may continue through the evening commute.

The accident occurred shortly before 1 p.m. Wednesday. It involved an unidentified trespasser who was struck by an Acela Express train just west of the Hamilton Township station in Mercer County.

None of the 170 passengers and crew aboard the train were hurt. It had departed from Boston and was headed to Washington.
