George--looking at your wiring plan, I have easy questions. Why do you have separate wires in different colors going to the outer rails? I am just connecting my outer rails together. Also, what is that BLUE TMCC note? My TMCC base is really just "one wire" connected to the ground side of my 3 TIUs and the grounds of all channels on all TIUs are electrically tied together. I think what I have done is good enough. But I am never sure.

OK, easy answers:

1. The Black wire is ground.  The Green wire is used for insulated rails at various points (where needed).  The outer rails are not tied together.
2. The Blue TMCC note is probably a bit misleading.  I do have the TMCC wire running to all the ground wires of all 8 power supplies on their way to their respective district tracks.  It's overkill, pure and simple.  One TMCC wire would do it.  But do note that all grounds are tied together, including the accessory transformers.  I'm sure what you've done is just fine.

You can follow the layout building thread "PRR Panhandle Division 2.0" on the Photo sub-forum.
