Re: DETECTION BLOCKS
I would suggest getting a book on DC (analog) wiring and follow the directions for two-rail wiring, not common rail, and cutting gaps in both rails where you want a block to end. You will need a detector for each block.
There is no set of rules for block length.

Subject: [WiringForDCC] DETECTION BLOCKS
I am building a new layout using DCC and want to install signals. I understand that this requires I set up a detection block(s) for each signal. Blocks are also set up to distribute power throughout the layout or to add reversing sections. My question involves my confusion regarding how each of these blocks fits together. I isolate power blocks by cutting each rail going into and out of the block – a total of 4 cuts per block. I feed power to the block through feeder wires connected to both rails about every 3 feet. What cuts do I make to set up a detection block? As best I can tell, I only need to isolate one rail for each detection block with a cut on either end and run the power lead to that rail thru the detection circuit with the other rail being powered by the normal track feeder. Is this correct? I also need to determine the location and length of each detection block – is there a good reference to read to help me there?
