Hello, would anyone out there happen to have a visual diagram for using two DC transformers for two train operation. I have an isolated outer loop with two inner loops and they are all switched. I have the Atlas 215 and 220 selectors also, I am using MRC transformers for both loops. Looking for a diagram that I can visually utilize since every time I see it written out I just confuse myself more. Thanks for any info. BZ
Your post seems a little vague to me but from one DC modeler to another I did some digging and hopefully this will be of some help to you.

I use switched DC too, but I agree we need a sketch of what you want to do.
You can use as many controllers as you like as long as they are properly isolated from each other.
The red circles are where the track isolators are located.
I am guessing this would be two blocks.

Yes this would be two blocks. You may want to share a common wire between the two packs.

Something like this would work for you.
I believe that is what I'm looking for been searching the interweb for a while,
Thanks Chessie much appreciated.
