Given London has figured out 24 hour Tube Service for a few days a week, do we think Toronto could? At least on Yonge once ATC is live?
We could, but ATC doesn't make any difference for it. The power substations for TTC power both directions of track through a section without capability to shutdown/isolate a single direction. Single track operations through a maintenance area aren't practical without modifications.
You might get away with alternating between Yonge (odd days) and Spadina (even days) for service but we could have implemented that model decades ago, so it doesn't seem likely going forward either; ATC doesn't change the cost equation much as open stations are far more expensive than running trains.
