A 151-car-long Canadian National train derailed just outside Detroit on Sept. 29.
Thirteen cars left the track, and three of them were carrying liquid chlorine and unrefined alcohol. Warren Fire Commissioner Wilburt McAdams said those tanker cars remained upright and only a small leak in one of them was spotted. There were no injuries in the derailment.
McAdams said track near the accident was bowed, but it remained unclear if the track was the cause of the derailment or if wheels of one of the rail cars were the culprit.
As crews worked to clean up the scene, traffic was clogged around the area. Police Commissioner Bill Dwyer encouraged the traveling public to avoid the derailment area.
