None of the train's crew members were hurt but there was a report of someone suffering from smoke inhalation, Tim McMahan, a spokesman for Union Pacific Railroad, told the Associated Press.

Some of the train's cars carried lumber and others were tanker cars.

McMahan said he did not know what was inside the tanker cars but that there were no reports of any leaks.

Camille Kimball, who was riding her bike under the bridge before it collapsed, told CBS 5 the noise of the train got extremely loud and as she came off the bridge.

"I turned around to look and got the fright of my life," she told the television station. "Now there's fire pouring into the lake from the middle of the bridge. ... It' looks like a scene from hell, truly. A scene from hell. ... The flames are intense and the sky is filled with black smoke."
