Investigators believe extreme heat may have caused part of a Union Pacific coal train to derail in Saline County.
Sparks from Sunday's derailment touched off a fire that scorched several acres of wheat stubble about six miles west of Salina. No one was hurt.
The 106-car train was traveling from Denver to Kentucky. Twenty-seven cars went off the tracks. Union Pacific spokesman Mark Davis says extreme heat can cause metal tracks to expand and warp.
Cleanup was expected to be finished by Tuesday. Davis says six trains pass daily between Denver and Kansas City. The trains were being rerouted through Nebraska until the derailed train can be cleared.
