I am using Atlas O track and turnouts and wire all turnouts on all three legs. I have my two main lines connected via Atlas O turnouts. So, I have a power drop at the connection point of the two turnouts that connect the main lines. I have the layout sort of wired for DCS using track blocks. For conventional operation, how would I isolate the track blocks were the two mains are connected via Atlas O turnouts? Thanks. Peter

You just have to isolate the center rail for each power district. With Atlas track, you can just take your Dremel with the handy cut-off wheel and slice the track, works fine.
You can isolate two tracks by substituting an Atlas insulated joiner for the black rail joiner connecting the center rails.

They come 16 pieces per blister pack.
If you are using two separate power packs you need to watch the polarity. It can be difficult id you are using and old pack with a non-polarized plug.

As long as that's where you want to break it...
Not sure I understand - I pointed out that I want to power all three legs of each turnout, therefore, the point at which the two mains should have a break is the exact spot where I need to put a power drop - the short diverging legs' Connection point.
Could you be clear, are you using two or three rail track?
A diagram of your situation would probably make it easier to explain...
Sounds like you have a plan, I can't think of a better way.
