Time...It marches on...without ever turning around to see if anyone is even keeping in step.
The PM42 must go BEFORE the BDL168. The PM42 cannot connect to the track in the same section as the BDL168.
I think you are in way over your head here.
The input to the PM42 should come from the command station. Each of the 4 outputs of the PM42 should be connected to a power input of the BDL168. Completely eliminate to connection from the command station to the 4 power inputs of the BDL168. Connect the detection segments of the BDL168 to the appropriate segments of the track. DO NOT CONNECT THE PM42 TO THE DETECTION SEGMENTS OF THE TRACK.

The image above is an updated version of my layout map with markings and labels and a color code representing the detection sections.
And to be back on topic, the answer to the question is once again, "it depends". Some people isolate the area around a turnout, to have an interlocking defined so that it can lock out the turnout when occupied. Or the entire area around a crossover. And then one or more blocks in the track connecting two of these interlocking areas - it depends on the length of the track and the train lengths that will be run. If the section of track is only 1 1/2 train lengths, it's kind of silly to divide it into more 2 detection blocks. Stub end parking sidings are not usually detected, unless you intend on trying fully automated operations - then they need to be detected.
It's a lot of wires - no way around it. Effectively 16 times the wiring, as each section of the BDL168 runs out to the layout for multiple feeder drops to each detected section. You will end up with a LOT more feeders and a lot more gaps cut in the rail. No way around it, it's how detection works.

The moderators could be merciful and lock this thread.
Meanwhile, alloboard needs to do five things:
1. Get the layout up off the floor.
2. Get some on site expert advice and assistance in completing the wiring.
3. Learn the proper wiring techniques and the function of each electronic component.
4. Simplify the entire process and quit trying to build an ultra-sophisticated electronic complex.
5. Learn to communicate more effectively on this forum and establish better dialog.
I like the ''toaster'' one.... LOL...

ALLOBOARD,
No offence to You, or anything,bad to say,,, But in my own opinion,,, you are trying to build a tremendous,house, without a foundation, even if you did want to build some sort of table,in that room,you would have to remove,everything that you have done so far,in order to do so,,, Good Luck,,,
The above image is my drawn image and the illustrated diagram from page 6 of the Digitrax BDL168. The black rectangles are the double gapped insulators. Based on the map if this section of my layout equal to one PM42 section assuming 4 detection sections will go to it, where would you suggest for me to put the four detection sections because the turnouts, the long lengths of the tracks, and the multiple lanes makes the wiring a little puzzling to me. Everything else is working out perfectly thanks to everyone's help in this forum.
Good suggestion. I'm currently thinking of a re-design.
Alloboard:
Why not take the time now to think of a re-design of your layout or part of it so that your table(s) will fit into the space you have? All of us have built layouts and then made major changes to allow for better running or to better utilize the space we have. Your most important consideration is to get it up off the floor on to a stable base so that your work will yield the results you want not frustration.

I'm willing to get my layout off the floor but, I will need my layout on the table to have a turnaround, which may not fit within that space. I will definitely get all of those electronics off the floor.
I will label everything and use color coded wiring. Your wiring looks nice and organized.
He has already been given lots of good advice and he doesn't seem to want to listen. It's sad but he will probably have to learn from his mistakes.
In addition to the electrical mess, no way that track is going to stay together for long, the joiners are going to flex and lose tension.
Indeed. Normal plastic bubble wrap and bags is an even greater static generator then the bare carpet, and the anti-static type of palstic (often a pink color) is actually somewhat conductive, so you wouldn;t want to lay the boards on any of that stuff. A small panel off some wood material, or even a piece of that white sleving material, like seen on my mounting shelf or my test track, is the way to go. There's not much danger of fire with the relatively low power of everything, but all those board did not come cheap and to have one fry from static or a wire accidently falling onto one of them would not be good.
May I add..............
Get yourself a piece of 1/4 inch plywood or masonite - perhaps 1x2 or 1x3 feet - and mount your electronics on that, and as previously suggested, label everything.
I would also use color coded wires as practical.
In my opinion, you are in a "self defeating mode" by having your trackage and electronics set up on the floor. You are wasting time and effort and bringing only frustration upon yourself.
Of course I understand the lure of fancy electronics and the fire to get trains up and running........... but putting it all unmounted and on the floor is just an exercise in futility.
Enough said.
ENJOY !

Save yourself a lot of future frustration. Label everything.
YIKES !
Don't get electrocuted !
True I don't even want to imagine the horror of that type of issue!
Well, it DOES matter if you have more than one booster, because of one section is wired opposite the other, when a train crosses the gap between the section powered by booster A into the section controlled by booster B, it will be a dead short.
The type of Loconet cables also matters, if the downstream device is a booster or a BDL168, especially if adding RX4s for transponding. Proper data orientation cables throughout will aboid problems. A phone cable flips the wires, which is OK for the Loconet signel and the ground, but reverses the phase of the Railsync signals in the same cable, which is very critical for the transponding since it works by allowing the decoder to send a signal on the rails when the DCC signal is at the 0 point of the square wave. Having one crossed cable somewhere in your wiring chain can result in hair-pulling levels of frustration when it doesn;t work, because just looking at the outside of the cable, all looks to be fine, and the problem isn;t immediately obvious. So take care int he wiring to make sure nothing comes back later to bite you.
Polarity is not and issue with Rail A and B comming straight from a Digitrax booster unlike DC but from what I've learned polarity is an issue with a power management like the PM42, so I make sure that my rail A and B wires are always matched at the right side.
Thanks for your help.
To the OP..........
You can buy plastic sawhorses at Sears hardware, but a better choice would be to go to Lowes/Home Depot and get a few "sawhorse brackets", and build your own. Get a few 2x4s, and a saw, and you are in business for relatively few dollars.
