I was in the same situation as RJR. An already functioning conventional layout with common ground buss wiring trying to incorporate DCS. Once I got into command with TMCC and DCS I wasn’t going to run conventional. I had no need for toggles except in the passenger yard sidings and engine facilities. The rest were removed. The ones that remained. The track power is done with relays. Eliminating long runs back and forth through toggles. All done with common ground. The more recent area does incorporate some star wiring. I use Gargraves track and Ross turnouts. Pretty much every rail has an attached wire. I think relying on track pins or joiners to power up a long block with star wiring may give you problems down the road. Unless the rails are joined by jumper wires. I believe the biggest key wiring your layout. Is to use quality wire and secure connections. Not so much how it’s done as far as star wiring or common ground. I use fourteen gauge feeders soldered to twelve gauge buss wiring. I’ve seen both methods yield great results. Keep your switch motors on a separate power source.
What you do need to keep in mind when running TMCC. Is the ground plane issue when tracks pass over one another. I had one area in a hidden tunnel that had a loss of signal with some engines. Easily fixed with a wire over the problem area run to a wall outlet.
