A train derailment near Big Lake is disrupting traffic and slowing the train company's main line Saturday.

According to the Sherburne County Sheriff's Office, the BNSF train was carrying consumer goods when it derailed around 3:15 a.m. At least 15 rail cars were involved, blocking the crossing at 172nd Street NW. between 197th Avenue and County Rd. 14.

A BNSF representative confirmed the derailment and said crews were working "as quickly and safely as possible" to clear the wreckage.

The cause of the derailment is under investigation. No injuries have been reported, and the Sheriff's Office said there was no threat to the public. It's unclear what goods the train carried, or when crews expected to clear the wreckage.

A broken rail track caused a BNSF train derailment in Raymond, Minn., last year, spilling ethanol and corn syrup, which caught fire. Hundreds living nearby were forced to evacuate. Estimates at that time suggested repairing damage to railroad tracks and equipment at $1.9 million. The environmental cleanup was estimated to cost $1.6 million.
