On Monday morning, BHP was forced to derail a loaded iron ore train on Monday morning after it travelled 92km without a driver.
The train was travelling from Newman to Port Hedland when it stopped to allow the driver to inspect an issue with a wagon. While the driver was outside the train, it took off with no one on board.
At the Australian AGM this morning, chairman Ken MacKenzie said most importantly, no one was hurt in the incident.
CEO Mackenzie said the company was always investing in safety initiatives in rail and suggested there were planned upgrades that may have prevented the accident.
He said it was too early to speculate on the cause.
"I'm being a little bit cute with my words, but this was a deliberate derailment," Mackenzie said.
