Burlington Northern Santa Fe officials inspect the 29-car train derailment in Tower City, N.D. An eastbound BNSF Railway train derailed at the west end of town, toppling 29 loaded coal cars and spilling hundreds of tons of coal, said Gus Melonas, BNSF Railway spokesman from Seattle. No one was injured, and there is no environmental threat, he said. This is the fifth train derailment in the past four years in the roughly 30-mile stretch between Mapleton and Tower City, N.D.
