As a result of the collision, 4 locomotive units were destroyed, 23 cars derailed, and hazardous materials caught fire in the wreckage. As a result of the fire, eight families were evacuated from their homes. A brakeman on train 3211 was killed, and the three other crewmembers of that train were injured seriously.
