Two trains, one carrying crude oil, collide, catch fire near Casselton, North Dakota

Authorities urged residents to evacuate a small North Dakota town late Monday after a mile-long train carrying crude oil derailed nearby after colliding with another train. The Cass County Sheriff's Office said Monday night it is "strongly recommending" that people in the town of Casselton and anyone living 5 miles to the south and east evacuate to shelters set up in Fargo, which is about 25 miles away. Casselton has about 2,400 residents. The sheriff's office said the National Weather Service was forecasting a shift in the winds that would push the plume of smoke down, possibly posing a health risk. Earlier, authorities had advised nearby residents to shelter inside their homes. The freight train carrying crude oil hit another train hauling grain that had derailed on Monday afternoon, triggering an explosion and sending flames shooting more than 100 feet into the air. No injuries were immediately reported.
