I have three individual loops, usually providing power to each from and individual brick.
If you have an individual brick for each loop, seems you're all set. Curious why the interest in sharing bricks/controllers?
For your example of running 2 subways on 2 loops using 1 brick/controller, then don't both subways do the same thing...with overlapping station announcements and such. That is, it seems separate bricks/controller guarantees adequate power for each loop and maximum flexibility in what each is doing?
