I've always been interested in the ATC (automatic train controls) used in mass transit rail systems. -- I once had a job writing instructions for rail car maintenance, that morphed into managing new car training for the Washington Metro system. And once I took a train down the mainline in Cleveland, and the ATC signals shut the train down dead because I did not slow fast enough coming into a station. Only had about 8 seconds to brake to speed limit and didn't. So the auto train controls interest me. It was a neat expereince...

You must know they run engineer free ore trains in Australia?

Some of the mass transit systems in the US could run automatically. The controls are there, but studies showed people will not ride on them without an operator.

iron ore doesn't care. I do believe its hematite, not pellets that they produce there.

in the North East we can't even trust the commuter rail with engineers at the controls due to corrupt management and inept maintenance.
Just looks at one line of NJ transit the NEC, it has failed trains almost every day of the week.

On another note, the highest train line in Europe runs really well, in Switzerland.
Nothing like going up through the center of the mountain.

The VLA and Murchison Crater are on my list of places to visit when I go to AZ to visit my son this year.
