Official: Derailed Train Car at Canada/Michigan Border Leaked Sulfuric Acid

July 1, 2019

About 13,700 gallons of sulfuric acid has spilled from one of about 40 freight train cars that derailed in an international tunnel connecting Michigan and Canada.

Canadian National Railway spokesman Jonathan Abecassis says the chemical was contained at the site and poses no threat to public safety.

Abecassis said the derailment occurred about 4:30 a.m. Friday and is under investigation. No injuries were reported.

The tunnel beneath the St. Clair River connects Port Huron to Sarnia, Ontario. It’s operated by Canadian National Railway. The train was in Port Huron at the time of the derailment.

City manager James Freed says the wreck involved about 30 to 40 of the train’s cars and caused “significant damage” to the track in Port Huron. It was not clear when the tunnel would reopen. No injuries were reported.

The train was headed into Michigan at the time of the derailment, which was reported about 5:45 a.m. to Port Huron officials.

Abecassis says the cause of the derailment is under investigation.

Freed says thousands of train cars pass through the tunnel daily. He says trains are being rerouted to a crossing in Detroit.
