The Canadian National Railway said cleanup was ongoing, Monday, after several train cars came off the tracks in St. Clair County overnight.
It happened as the train was passing through Capac, about 45 miles north-northeast of Detroit. Four cars were empty, but one that came off the track was carrying ammonium nitrate.
Spokesman Frank Binder said the accident happened about 12:30 a.m. No injuries or evacuations were reported.
Binder said four rail cars on the eastbound train were empty at the time of the accident that left two cars on their side. He said the car carrying ammonium nitrate remained upright but sprung a “minor leak” that was “quickly contained.”
Binder said it was not immediately known where the train originated, where it was heading or whether other train traffic would be affected.
No cause has been determined. Canadian National and federal authorities were expected to investigate.
