WELD COUNTY, Colo. -- A train derailment caused about 25 coal cars to overturn late Wednesday night, the Weld County Sheriff's Office said.
The Union Pacific Railroad train derailed about 11 p.m. at Highways 85 and 392 in Lucerne, about five miles north of Greeley. Cargo spilled from the coal cars, the sheriff's office said.
No one was injured, but one structure was damaged. The sheriff's office did not say what kind of building was involved or the extent of the damage.
The cause of the derailment is not known. Union Pacific Railroad crews from Denver and Utah will lead the investigation.
Highway 392 was closed in both directions after the derailment but has since reopened.
Several crews using heavy equipment are working in a major cleanup of the coal, which spilled on the side of the tracks that run parallel to Highway 85.
The sheriff's office said cleanup is expected to last several hours into Thursday afternoon.
