Service was partially restored by about 12:30 p.m., but passengers traveling through the area were advised expect residual delays as service levels return to normal.
The incident happened in the CSX Oak Point Yard in Hunts Point around 9:15 a.m., with the company saying eight cars left the tracks.
The cars that derailed were empty, and no injuries were reported, but one of Amtrak's tracks was blocked as a result.
Amtrak had to inspect their infrastructure before resuming service.

Seven of the rail cars were empty, and one car contained lumber. There were no injuries as a result of the incident, and no hazardous materials are involved. CSX has crews on scene who are developing plans to re-rail the affected cars and restore the scene of the incident for operations. CSX contractors are en route to the scene to assist in the recovery. No timetable for completing that work has been established at this time. CSX will work as quickly as safety allows to restore the area to full operations. This incident is impacting Amtrak's service on tracks adjacent to the scene. Passengers should contact Amtrak directly for the latest information about the status of service through that area. Safety is CSX's highest priority, and our goal is zero accidents.
