PORT HURON, Michigan (AP) — Safety officials in the United States (US) and Canada are looking into a multi-car train derailment in an international tunnel connecting Michigan’s Port Huron to Sarnia, Ontario.
The National Transportation Safety Board said investigators have been sent to Port Huron, northeast of Detroit.
About 40 freight cars left the tracks around 4.30am last Friday in the tunnel beneath the St Clair River. Port Huron City Manager James Freed has said the wreck caused “significant damage” to the track and that it was not clear when the tunnel would reopen.
No injuries were reported.
Canadian National Railway spokesman Jonathan Abecassis said about 51,859 litres of sulphuric acid that spilled from one car had been contained.
The safety board said preliminary information indicates the derailment point is in the Canadian side of the tunnel.
