A CSX Corporation train transporting North Dakota crude derailed Monday in West Virginia, setting multiple train cars and one house on fire and sending at least one train car into the Kanawha River.
The train was moving 109 cars from North Dakota to a Plains All American midstream facility in Yorktown, Virginia when it derailed around 1:20 p.m. Monday about 33 miles southeast of Charleston.
One person was treated for potential inhalation of fumes.
No other injuries were reported.
West Virginia governor Earl Ray Tomblin declared a state of emergency Monday in Kanawha and Fayette counties.
About 200 residents from two towns were evacuated after a house one mile from the accident scene caught fire.
Cleanup is expected to take several days as emergency crews wait for some of the fires to burn themselves out.
West Virginia American Water is testing the Kanawha River for contamination.
West Virginia State Police First Sergeant Greg Duckworth told Reuters that train cars exploded about every half hour in a chain reaction with about 10 cars going up in flames throughout the day.
Florida-based CSX has not commented on the accident.
The derailment happened about 200 miles west of Lynchburg, Virginia where a CSX train traveling to the same Plains facility in Yorktown derailed and exploded last April.
