Which track and switches are you using?
I ask because you do have to insulate "blocks" or sections of tracks from one another. That may be a pain.
Also, I ask about the switches, because many switch motors do cause interference to the DCS signal which is remedied by the 22uh choke previously mentioned.
It would also appear that running one hot and daisy chaining that to the other toggles hot would not be a problem.
I have also read some of Barry's posts that dispel the myth of "equal lengths of wire".
You can locate the terminal board at the current power and control location and run the feeder pairs from there.
Based on Barry's recommendations for length's of the power divisions or blocks, cutting the main area into a quadrant would come close and cutting the yard\TT leg in half would probably be good due to the amount of track in a small area. (pic attached)
Rewiring with the heavier gauge wire in the "star pattern" should solve the issue. If you have other signal issues after that, then the chokes may be needed on the switch motors.
