The switch was thrown remotely from Perth, which is about a 2 hour flight from Port Hedland. I'm a bit surprised that this happened. I went through more safety training (videos, on site, daily safety meetings) prior to being allowed access to the BHP locomotive servicing facility in Port Hedland than any other customer / industrial manufacturing facility that I have visited in my 30 years on the job. Granted, this was very different than any other customer that I have visited.
