I finally found a Digitrax solution I like

I have never seen the need to add so many master controllers to a layout unless there is complete separation of the track segments.

Even at UNSMRCA where there was a lot of track the system was wired from underneath only requiring a single master and some boosters.

I'm reading that as that he's using the spare command stations as boosters.  Unnecessary, but if you get them for free, why not.

Yes!! Experience has taught me that even on the largest of layouts, more than one command station is just more trouble.
I have an 8 amp Command Station and three boosters and I finally got reliability by reducing it all back to the one command station. Earthing the units together, putting jumpers where required all failed to introduce reliability.
Only problem is the ramp meter is showing 14.5 v and 3.1 amps right now with all track sections and Tam Valley units fired up, and all locomotives silent.
I did notice 4 flat top T's climbing a grade (helix) and hauling 50 wheat hoppers was stopping and starting, which is a new phenomenon. And I did not look at the ramp meter to see  what was happening. Sad
But I think, all things being equal the 6.5 amps that a DCS200 can deliver to the track should easily run my layout. I have been told the command station does not actually deliver 8 amps.

If I have it right,
You must run a new bus line from each booster, and feed a section of layout that is isolated from all other boosters, without any cross feeds.
The Digitrax manual seems to suggest that you might have problems crossing between boosters, but I am afraid my electronic skills are so bad that I fail to understand, half of the geek speak these manuals spell out, sadly.
But anyway my initial set up (which did work) simply daisy chained 4 units together and fed a 45 amp bus line, with 25 amps, around the whole layout.  45 amps??  My God! why did it not burn?

Edit for David Smile  Hey mate we made another fantastic leap forward today.  We spent 6 hours removing links with the last two track sections throwing a short.  We found the wrong connection about 5.00 pm and the section powered up. Now all I have to do is reconnect about 30 pairs of droppers and all will be good. Fortunately I plug all my droppers in with spades and so an hour tomorrow should have trains circulating again.
