It’s rather different to that since the TL core will require a qualified driver at the controls throughout, even when ATO goes live. I’m sure you’re fully aware of that, despite that somewhat loaded comment.
I know you and others on here aspire to minimal staffing and “guard only operation” autonomous trains. Let’s see how that goes over the next few decades given that even the tube isn’t approaching driverless yet and unlikely to for quite some time. Many years, in fact. HS2 hasn’t even been built yet, but will still have drivers (and hopefully a second person on board, even if only an OBS or similar) ...
I suspect you and I, as 30 somethings now, will both be geriatric, or 6 feet under by the time autonomous mainline trains are in mainstream use. Should I remain in this job long term I fully expect to be able to take an autonomous car to work in future (not that I want one of those) in order to drive a train under ATO or, most likely, still manually.
