Weather is being blamed for a train derailment on the Floyd-Knott County line.
It happened Monday morning at the intersection of Route 7 and Route 899.
Transportation officials say the accident could be a result of the extreme shift in temperatures
Crews believe the temperature change from warm to cold was too quick for the rails to handle.
The six cars didn't fall over, but officials say their wheels came off the tracks.
Workers say going from very warm Sunday to cold in a few short hours made the rails shift and then the cars on top didn't stay on them.
No one was hurt and the accident didn't cause any damage, but the CSX train cars were loaded with coal.
Crews spent all day picking up the six cars and putting them back on the tracks and cleaning up coal.
The stopped train also blocked highway 899 but road officials didn't report it causing any problems.
Officials say other trains were stopped all day during clean-up and either held where they were or re-routed.
