Why no autonomous railcars ? Such systems exist since many years for underground railways, for example in Paris. And in France we have the OrlyVal to Orly airport since 1991 ! I remember, when I was a student in Paris (1973-1977), that for some underground lines the "driver" looked out of the door and pushed only a button to validate the start, the train started and accelerated automatically ; there was an induction system between the rails, which transmitted information to the trains. The only issues could be caused by railroad crossings, which don't exist on such systems, if a car gets stuck.

In the end though, it'll take a human to unload it...

They’re trying to get autonomous trucks, running in 2D. Why not railcars that run only in one dimension. The San Francisco system (BART) has similar “drivers” but in 1975 they proved useful. It snowed in the Bay Area and the computers weren’t programmed for ice on the track. So the trains slid through every station. The “drivers” actually had to drive, backing the train back into the station.

Liability, in the US. No one feels comfortable with a ‘headless’ train. Unless it is the airport point-to-point. When BART was cloned from the already archaic Boston Railway, computers were becoming excessable. My Mentor was the Director of Lawerance Berkeley Labs (related to U.C. Berkeley but the Federal side). He was tasked to evaluate the GE computer to run the trains instead the typical Ops Session (Mommy, can I go now? No, son. You must wait for your Father)
and if you look at America’s ATC failures, even a human can screw it up worse, when it fails.
15 years ago, I rode in the cab of a German freight, thru Switzerland, to Italy’s transfer yard. As we passed EVERY Green (or Yellow), we had 5 seconds or the brakes went on. ALL stop. So even with a system that has worked, it still wanted verification.
Then there are the cars/trucks, humans with headphones or so entranced by a tic-tok, rocks/trees.
And many of you have seen trackwork.. . .
