Derailment evacuation ends

South Carolina say an evacuation order has been lifted for all but four homes following a 39-car train derailment in rural South Carolina. Investigators with the NTSB and Norfolk Southern do not know the cause of the 39-car train derailment and offer no additional details. Aiken County Hazmat officials have detected no harmful spills at the scene even though one of the Norfolk Southern tankers carries anhydrous ammonia and another ammonia nitrate, or dry fertilizer.
