A railroad spokesman said one rail line in Whitfield County remains closed this morning after a Sunday accident, and some trains with perishable freight are being rerouted through Birmingham.

A Nashville-bound freight train jumped its tracks around 6:35 p.m. Sunday northwest of Dalton between Interstate 75 and U.S. Highway 41, according to Whitfield County dispatchers and railroad officials.

Of the 10 cars that dumped over, six were full of cotton seed, one carried lumber and one was empty, according to Gary Sease, a spokesman for CSX, which owns the train. No hazardous materials were involved, and no one was injured, he said.

Mr. Sease said the cars were “rerailed” around 3 a.m., and the track should open this afternoon once it is repaired. The investigation into the cause of the crash could take a month, he said.

“The way you prevent accidents is to learn from the ones that happen,” Mr. Sease said.
