Hi Joe, Just thought I'd throw in my 2 cents worth. I agree that the idea is self defeating but for a different reason...by wiring back to the contol panel from the block one is just duplicating the wiring. #20 or #22 hookup wire will provide more than adequate current/voltage to the blocks with out any appreciable loss. There's just not enough resistance there to worry about in HO or N scales. So if you are having a centrally located control panel I don't see any problem with just feeding the panel and then wiring out to the blocks from the panel. The buss idea is great where you have the block toggles on the facia of the layout at each block but that's just for convenience anyway. The trick is to have an adequate power supply to begin with. Any good power pack/controller with 2AMPS or better output will be more than adequate for most home layouts....Hope this helped....Vic
