The preschool is hiding behind the hill on the railway line? I wish they'd stop building these schools on the train tracks, it's so irresponsible.

I believe that Australia has an automated freight line.

The original intent of the Black Mesa & Lake Powell (hauling coal to a power plant) was for it to be fully automated, but I don't know if it ever ran without a human in the cab.

>> has an automated freight line.

I didn't know about that, but is it a "freight line" or a "freight train"? If it is the former, a dedicated line used only by the automated train, then it isn't all that removed from disneyworld: a single-use train on a dedicated line. And Australia is notoriously flat.

I'm from the west coast, where driving a heavy train through the mountains is serious business, but disasters can happen anywhere. The latest epic disaster in Canada was caused by a train that was unmanned at the time. It was parked.

Yes, I've been to Tehachapi, Cajon, and Donner Passes. And Cima Hill, and Ash Hill, and Goffs. I know what mountain railroading out west can be.

Maybe the gnarliest scenario I know of out there is: There's a major brush fire on Cajon. Like, 20-foot-high wall of flame. Is it far enough away for you to try to get the train past it? (With maybe 4000 gallons of diesel fuel under each locomotive, and maybe liquefied petroleum gas tank cars in the consist?) Or do you park the train, and hope the fire doesn't come to you? I mean, I guess an AI can make that decision without being influenced by concern for its own survival. But I suspect that most train-driving AIs don't have a really good set of training data for this scenario...

I suspect most human drivers don't either. The AI might not make a particularly good decision, but is there any reason to believe that a human would make a better one?

There's a 1700km track network with both automated and non automated trains, so slightly larger than disneyworld.

"Australia is notoriously flat"

Citation needed.

REally? You need a citation to know that australia is flat?

"Australia is the lowest, FLATTEST, and oldest continental landmass on Earth[4] and it has had a relatively stable geological history. Geological forces such as tectonic uplift of mountain ranges and clashes between tectonic plates occurred mainly in Australia's early prehistory, when it was still a part of Gondwana. Its highest peak is Mount Kosciuszko at 2,228 metres (7,310 ft), which is relatively low in comparison to the highest mountains on other continents."

Russia is big. Switzerland is small. And Africa has gets less snow than Canada. (Citations needed)

The basic route of this train (Newman to Port Headland) is a gentle slope to the coast. +175 and -700m over a 400km journey. (Google maps) Compare that to a route in western canada: Canmore Albert to Salmon Arm BC, the same distance but +2500m and -3500m.

Being the flattest continent does not mean that the continent is flat. My point is that there is still plenty of hills and steep terrain around. It's not self evident that if you build a train line somewhere in Australia, that line will be flat. In fact the Pilbara automated rail network does contain some steep sections.

It still snows in Africa, and if you tried to climb Jebel Toubkal without a jacket I don't think knowing that Canada is snowier would provide you much comfort.

Yep, the iron ore trains are largely automated these days, I believe.
