Railroad personnel remain on the scene along with local emergency services, according to BNSF general manager of public affairs Lena Kent.
The Federal Railroad Administration is on the ground and will be involved in the investigation, U.S. Transportation Secretary Pete Buttigieg said.
The cause of the derailment is under investigation. Meanwhile, the main rail line in the area remains blocked, along with a nearby highway.
In recent months, such incidents have raised concerns among advocates for greater rail safety in the U.S. The dangerous derailment last month of a train carrying toxic chemicals near East Palestine, Ohio, caused an uproar.
