Makes sense. Many urban rapid rail systems have been autonomous for a long time.
Apparently from 2019. A couple of things stood out
Wondering what the payback period and IRR of this is. I'm speculating that companies that make the switch later will have much lower funding costs.
Pro: Rio Tinto says AutoHaul has already helped to increase average speeds by 5-6%, and the company is optimistic that this can improve further. Removing the two to three driver shift changes has also cut an hour from the average journey, while the section run time variation between AutoHaul services is just 15-30 seconds compared with 2.5-5 minutes when the trains were manned. This is helping the operator to plan more efficient train schedules, reduce bottlenecks and boost productivity. Con:
While initially cited as costing $US 518m at its official launch in 2012, Rio Tinto’s investment soared to $US 940m by 2018, according to figures from the company’s official results, 80% above the initial budget. The full deployment of 100% automatically operated trains in June 2019 was also four years later than planned.
