Great questions! I’m going to suggest that you aren’t going to see doubling along part of the route. That would require a point where all the doubles are split off and attached to trips running the other way. This is obviously possible but even with modern coupling equipment they don’t like having coupling/uncoupling happen partway through a trip. It takes time to perform the maneuvers and increases the complexity of operations.
I imagine the passengers on the extra unit would be the bigger problem in that scenario haha. But what I was suggesting was that the trains which would be at the busiest segments at the busiest times would leave the yard already doubled.
If I'm not mistaken when I was in Tokyo there was signage at platforms suggesting trains on the same line fluctuate between 8/12/16 car trains throughout the day (or maybe I'm mistaken and it was just signage for different lines), so presumably it's a reasonable thing to do. But at 10 minute headways we would need 4 extra trains to cover just 20 minutes bi-directionally, which I don't think we even have?
