Central Indiana & Ohio RR
The old layout gone, it served as a nice test bed and learning experience for me and a place for FAILURE and just all out "what not to do if you did it again".
So I took all this and started right this time.

I've decided to use the "NODE" approach, there will be 3 nodes each containing all of what you see.
Command station (at one spot) and Boosters in all others.
Circuit Breakers
Specialist Power supply (8amp out)
Computer power supply (continual)
CMRI Detectors
CMRI Switch machine control cards
and a few other things

This node here is 2 foot tall by 4 foot long. The other nodes will be roughly same size or smaller.
Keeping everything neat is the prime goal and it makes it much easier on you in the long run (experience talking).
I had to bypass the toggles that are used to cut out the DCC Boosters/Command stations because they are only 3amp rated and I thought it was 8amp. Oops. Its a quick fix, and no biggie to bypass them for the time being!
Here is the work so far, little messy, but still being worked on.
