BHP has suspended all rail operations in Western Australia after a runaway train laden with iron ore travelled 92km with no one on board before it was deliberately derailed.
The footage shows the twisted wreckage of the two-kilometre long train, some carriages partly buried under mounds of iron ore.
The driver of the BHP-operated train stepped out of the locomotive early on Monday to inspect an issue with one of its 268 wagons and it took off without him.
One and a half kilometres of track were damaged in the incident, and the company expects its WA rail operations to reopen in a week.More news: 2-month-old Boeing plane crashed in Indonesia after key sensor replaced
However, it said, operations would be maintained and the use of reserves would mean there would be no interruption to supply.
More than 130 workers have been deployed to fix the track and recover the wreckage, with BHP saying it would be removed "over the next few days".
BHP has large iron ore stockpiles at port, so it is unlikely any scheduled shipments will be missed.

An investigation into the incident is being carried out. There was no indication of what had caused the train to move without its driver.
"We can not speculate on the outcome of the investigation, however we are working with the appropriate authorities and our focus remains on the safe recovery of our operations", the BHP spokeswoman said.
