Carl, thank you! I do prefer to use 2 fixed loops rather than 3. I will see how that goes. Your color coded version will help greatly. My MTH terminal blocks have a max of 12 connections. I have 2 of them. If I have to use another terminal block I can use my older TIU (magic bulb) for a 3rd fixed section which will be the station/yard area/lower reverse loop. I would use the fitters of 060 or 072 turnout entering that lower loop for blocks for that section.
This plan helps me visualize where to place terminal blocks. The TIU or TiU's will be placed at, or slightly above track level between the upper reverse and lower reverse loops (a bit to the right and closer to the lower loop. As of now I have:
Block "A" with 12 connections / blocks for the outer main and elevation/grade section....each to be labelled A1 thru A12
Block "B" with 10 connections/blocks for the inner main and upper reverse loop.....labelled B1 thru B10
Block "C" with 11 connections/blocks for lead (off of upper loop) to station yard area (lower reverse loop). From that reverse loop I would use the last turnout (at left side) which exits/enters reverse loop to inner main...labelled C1 thru C11.
My concern is at the 2 crossovers from inner to outer mains. I will use the fitters for blocking between connected turnouts....if I should have a passenger or freight train leave inner main ot outer, and immediately use the next attached turnout right back to the inner main would that move cause electrical problems...short, unstable amp/volt readings? I know I need to "phase" if I decide to also use the Z1000 transformer.
I will be rereading the DCS companion this p.m. or tomorrow a.m. .
