A train derailed, struck another train and caused an explosion reported CNN on December 30, 2013.
A westbound Burlington Northern Santa Fe Corp. train carrying grain derailed Monday near the town of Casselton, North Dakota, and was struck by an incoming eastbound BNSF train transporting more than 100 cars of crude oil resulting in several explosions.
BNSF Railway spokeswoman Amy McBeth said the grain train derailed and knocked several oil train cars sending them off the tracks, which caused the explosions.
Terry Johnson, manager of a grain dealer near the site of the derailment, said he heard several explosions after the incident.
"Each one, you could hear the explosion," he said. "It shook our building and there was a huge fireball."
"The town is covered with black smoke," he said. "The wind is blowing a little, so the town doesn't have to breathe it."
Sgt. Tara Morris with the Cass County Sheriff’s Office states that no injuries have been reported, but "with the oil on fire there are hazardous conditions, and we are directing all people in the area to shelter in-place and stay indoors."
