North Dakota town partially evacuated after fiery oil train derailment

The derailment happened amid heightened concerns about the United States' increased reliance on rail to carry crude oil. Fears of catastrophic derailments were particularly stoked after last summer's crash in Quebec of a train carrying crude from North Dakota's Bakken oil patch. Forty-seven people died in the ensuing fire.

The tracks that the train was on Monday pass through the middle of Casselton, and Cass County Sheriff's Sgt. Tara Morris said it was "a blessing it didn't happen within the city."
