Authorities in north-central Illinois say they're investigating the possibility that high winds caused a freight train to derail, damaging about 30 rail cars.
The cars left the tracks around 3 p.m. Sunday just east of Toluca near the Marshall County-LaSalle County line.
Emergency management authorities say an inspection of the tracks found nothing that would have caused a derailment. But there were reports of strong wind gusts in the area at the time that left behind broken power poles and downed wires. No injuries were reported.
A spokeswoman for the Burlington North Santa Fe railroad said Monday that crews are working to repair parts of the track damaged by the derailment and the line is expected to reopen Tuesday morning.
Toluca is about 100 miles southwest of Chicago.
