SHELDON - Twenty-five Union Pacific freight cars hauling sand and soybean oil derailed near this northwest Iowa town.
No one was injured, UP spokesman Mark Davis said Monday.
The derailment happened at 4:30 a.m. Sunday.
He said 20 cars were loaded with sand and five were hauling soybean oil.
The train, with 117 cars and two locomotives, was going from St. Paul, Minn., to North Platte, Neb., Davis said.
"Crews were working yesterday and through the night not only to clean up the rail cars but also 450 feet of track that was damaged," he said.
The line has been closed until the tracks can be repaired, he said. Officials hope to have that done by Monday night.
The line carries four trains a day, Davis said. Rail traffic has been diverted.
The cause of the accident is under investigation.
Sheldon is 55 miles northeast of Sioux City.
