Two piles of railroad ties were set on fire at a site just north of Pueblo, Colo., on April 11. Police believe the act was intentional.

The two fires were located off mile marker 108 in Pueblo County, just off I-25. The ties, owned by Union Pacific, were in two separate piles by train tracks. Due to Operations and Maintenance agreements with Union Pacific, BNSF responded to the incident and is involved in the investigation.

The Pueblo County Sheriff’s office believes about 10,000 ties burned, and traffic was stopped while crews fought the two blazes.
