The 79-car CSX train was carrying coal southbound toward Newport News, Va. A CSX spokesman says seven of the train's cars derailed near Quantico.
He says the train was not carrying any hazardous material and there were no injuries.
Mark Roeber, a spokesman with Virginia Railway Express or VRE, says the derailment will cause major delays.
"It will affect all trains," he says. "There are only two tracks that run through that area. Both are closed. So all northbound and southbound traffic is closed."
The CSX spokesman says clean-up crews are on their way to the scene of the derailment, but he couldn't give an estimate as to when the tracks will be clear.
