An iron ore train derailed in WA yesterday, however no people were injured, according to BHP.
A spokesperson for the company said a number of cars derailed on the Pilbara rail line at 6am on Wednesday morning, about 67 kilometres south of Port Hedland.
BHP expects to be able to reopen the line on this afternoon, and will report any loss of production in its quarterly operational review for December.
BHP said the incident had not affected loading or shipping at port, due to existing stockpiles at Port Hedland.
The Australian Transport Safety Bureau said it will conduct an "office based" investigation into the cause of the incident.
