Atc
ATC has definite financial benefits to any transit operator.
Its important to note however that there are many variables.
Vancouver for instance, operates much smaller trains, which means its theoretical savings per rider is lower.

Aside from variation in capacity; there is variation in operation. That's not only service frequency/level and capacity utilization but the question of how many staff are used on a train before/after automation.
For instance, we current have the SRT on full ATC, but there is still 1 staff person per train.
Our Subways we currently have 2 staff per train (Driver and Guard)
Would you propose ATC eliminates the need for 1? Or both?
The very much affects the issue.
Also affected is how you accommodate ATC (or at what cost). For instance Vancouver does not use platform edge doors; making it much cheaper to operate ATC, though not completely eliminating suicide risks etc.

Full ATC, with zero staff on trains, should produce a 'fair' financial benefit, though not an enormous one, though I wonder what we would deduct for increased vandalism costs?
****
Now, something I favour is implementing an one-fare system (no age-based changes) so that you can fully automate the fare system in stations with full fare gates.
Again, of course, if you replace those staff w/security and/or tourism/info staff you many not see the full benefit.
But if you went essentially staff-less in both trains and stations, you would def. rack up NET savings in the tens of millions. Though there are obvious safety implications.

Now the best deal probably comes from the new LRTs which will increase passenger load per operator by a large margin. THOUGH, this is only true where you can extend headway w/o making service poor.
So largely, a rush-hour benefit. Though still worth several million per annum.
The biggest savings is the ratio when bus routes convert, but the new rolling stock will actually be a bit larger than the current CLRVs
*note* - new LRT routes not being grade-separated means no ATC option
Though this plays into the age-based fair question again, as there will be no on-board fare collection or age verification.
I wonder how many fare evasion officers we end up hiring?
