Recovery of sulphuric acid that leaked from one of approximately 40 rail cars that derailed Friday in a tunnel crossing beneath the St. Clair River was expected to be completed Monday, according to CN.
The car contained nearly 63,000 litres of sulphuric acid when it was part of a freight train derailment in the tunnel connecting Sarnia and Port Huron, Mich.
