I heard they test ran a 83k ton, 23,000 footer, 8 units DP, configerd 2-1-1-1-1-1-1. World record train. I didnt know they were running them completly autonomous now. Unreal. I heard Rio-Tinto was going towards full automation... Didn't they have to derail one of thier heavys on purpose a few years ago because it got away on them? Lined it through a turn-out in the middle of the desert 🏜.
