It’s unclear what caused the train cars to derail.
The derailment prompted a joint response, including the FBI, Washington State Utilities and Transportation Commission, Washington State Patrol, Whatcom County Emergency Management, and local fire agencies.
The FBI issued the following statement: “Investigators are on the scene assisting local partners to determine the facts of what happened. At this point, it would be speculative to connect other events with this incident. FBI Seattle encourages anyone with knowledge of the train derailment to contact tips.fbi.gov”
Oil continued to burn in two of the tanker cars Tuesday night, but the flames were under control, according to the Whatcom Sheriff’s office.
