Authorities were responding to a freight train derailment Thursday in southeast Michigan, the latest incident as communities in Arizona and Ohio grappled with the fallout from collisions involving hazardous materials.

Emergency crews were on the scene in Van Buren Township, where about 30 Norfolk Southern Railway train cars went off the tracks Thursday morning. The derailment prompted temporary road closures which were expected to reopen by the evening, the local public safety department said on Facebook.

The township is located about 30 miles west of downtown Detroit.

While an investigation into the derailment is ongoing, Van Buren Township Public Safety said there are no reports of injuries and no hazardous materials were aboard the overturned portion of the train.

“There is no evidence of exposed hazardous materials. There are also no reported injuries,” the Facebook post says.

Congresswoman Debbie Dingell, D-Ann Arbor, said on Twitter that the U.S. Environmental Protection Agency, who responded to the derailment, found that the majority of derailed cars were empty and a rail car containing hazardous material was not derailed. 

The derailed train cars were currently being placed back on the track, Dingell added.
