Thank you Keith for responding to my question.
I have never had a layout of this size and I'm slowly learning as I go...trail and error, with more mistakes than I care to admit.
I have heard of the Star System. I do have a power block.
Unfortunately, I am not familiar with insulating pins, nor a power district.
I also do not understand your last recommendation " to jumper the 2 outside rails together at each power connection."
I really appreciate any information and knowledge you could share with me.
Attached are 2 photos of my layout, currenty.
