Approximately 10,000 railroad ties were set on fire at two separate locations in Pueblo County on Saturday night in what sheriff’s officials say is a suspected arson.

The Pueblo County Sheriff’s Office said in a tweet that deputies and emergency services teams responded to the fire Saturday night and halted BNSF Railway traffic while crews put out the blaze.

The only location sheriff’s officials gave was that the fire was near railroad tracks north of mile marker 108.

Investigators from BNSF are continuing to probe the fire’s origins, sheriff’s officials said.
