You can hook up in passive and it will generally work, but with limits:
You have a Buss wired Layout and no blocks.
All those drops send the DCS signal to the track, and the signals go both ways from each power drop. Now they are all crossing one another, this results in the tower of babel for electronic communication.
So you need to break the center rail between each power drop. That will keep the signals from crossing and all will be well. Isolate your sidings as well.
Be aware that passive does not put quite as much signal on the layout, but with a Rev L TIU (Current Version) you should be fine.
