PORT HURON, Mich. (AP) — 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 has been contained Friday 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. The train was in Port Huron at the time of the derailment.

Port Huron City Manager James Freed said the wreck caused “significant damage” to the track. It was not clear when the tunnel would reopen.

Freed said trains are being rerouted to a crossing in Detroit. </s> A CN train derailed inside the Port Huron-to-Sarnia rail tunnel under the St. Clair River Friday morning, with one rail car leaking sulfuric acid.

The rail company said in a statement that about 40 cars derailed in the tunnel, which connects Michigan to Ontario, in “various positions” while “at least one car with dangerous goods is involved.”

CN said in a statement Friday afternoon, a car containing about 52,000 litres of sulfuric acid has leaked as a result of the derailment.

“The sulfuric acid is contained to the site of the derailment and poses no danger to public safety or to the St. Clair River,” company spokesperson Jonathan Abecassis said. “CN is collaborating with the Municipality of Sarnia and St-Clair County as well as the Municipality of Port Huron.”

Sarnia’s Aamjiwnaang First Nation Emergency Planning said in a statement at least two derailed cars were carrying new vehicles which are blocking the Canadian side of the tunnel. Diesel and other motor vehicle fluids have spilled inside the tunnel, according to the agency.

According to Port Huron City Manager James Freed, no injuries have been reported and there’s no threat to public safety as a result of the train derailment.

Freed said U.S. Homeland Security and Emergency Management agencies have been briefed on the incident.

CN also noted there were no fires or injuries reported at the scene of the derailment, adding the cause of the situation is under investigation.

Transportation Safety Board of Canada said Friday afternoon, the agency will dispatch a team to Sarnia to assist in the investigation.

CN said trains are being rerouted, while there’s no estimation as to when the tunnel will reopen to traffic. </s> A freight train has derailed in an international tunnel connecting Michigan and Canada.

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

The tunnel beneath the St. Clair River connects Port Huron to Sarnia, Ontario. It’s operated by Canadian National Railway.

Railway spokesman Jonathan 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.

Transport Canada said on Twitter that it was sending an investigator to the scene, noting “should any safety deficiencies be identified, the department will take appropriate action.” </s> PORT HURON, Mich. (WXYZ) — St. Clair County says 19 rail cars are still inside the St. Clair River international tunnel following a trail derailment inside the tunnel last week.

According to the county, CN crews are working to remove the cars from the international rail tunnel. So far, they have removed five cars from the American side and 17 cars from the Canadian side.

When the trail derailed on Friday morning, 40 cars went off the tracks and spilled 13,700 gallons of sulfuric acid. At the time, the company said the acid was contained to the site of the derailment and posed no danger to public safety.

They are working to drain the liquid and as it accumulates in the sump retention area, draining continues. Air monitoring at the site and around the perimeter continues and shows no danger to public health, public safety, drinking water or water ways.

"Due to varying stages of the wreckage, contents and weight, a plan has to be developed for the removal of each railcar along with the equipment needed to do so," the county said in a press release.

According to the county, there are more than 150 people working on the American site 24 hours a day to resolve the situation. At this time, there is no timeline for completion. </s> Detroit — A train derailment in the St. Clair Tunnel could take days to repair, according to officials from the Port Huron Fire Department.

The derailment occurred just before 6 a.m. Friday morning, Port Huron Fire Department Chief Corey Nicholson said.

Nicholson said approximately 40 cars are off the track in the middle of the tunnel. Because of the number of cars and significant damage to the rail tracks, it could take several days to have the tunnel functioning again.

Officials said there were no injuries in the accident and there is no threat to public safety in the surrounding area. Since the derailment occurred inside the tunnel, U.S. and Canadian officials will work jointly on the clean-up and investigation.

The train was heading to the United States from Canada. The cause of the derailment is currently unknown. More information will be available as clean-up continues.
