Part of a freight train derailed and caught fire in Ohio’s capital city early Wednesday, shooting flames skyward into the darkness and prompting the evacuation of a mile-wide area as firefighters and hazardous materials crews worked to determine what was burning and contain the blaze. Norfolk Southern said it appeared about 11 cars of a southbound train derailed around 2 a.m. near Interstate 71, southeast of the Ohio State University campus. They went off the tracks north of downtown, in an industrial area blocks from residential neighborhoods.
