This is a loop, right?

[ATTACH]515080[/ATTACH

It's basically a dogleg but where the turnouts meet makes that end a loop if the train crosses the turnouts, right? The blue circles show where the polarity will change and the other side as well. So, I have to treat it as a loop with a Digitrax AR. I want to be sure where to put the plastic rail joiners.

Yes, you do have a 'reverse loop'. It does require
a reverse loop controller such as the AR1 that you mentioned.

Make the entire 'loop' the 'isolated section' including the turnout
on the right. The loop will be powered
by the AR1. Place insulated joiners above the turnout on the left and
below the turnout on the right. You'll also need insulated joiners
between the two turnouts.

Don R...hope you can help me out with my reverse loop. I've installed isolated track joiners as the loop comes around and back into my turn out but the train just dies when it hits that section. I flip the reverse switch on the transformer and nothing happens.
Should I ALSO be installing insulators on the other side?

Other side of what? The reverse loop? Yes. The loop needs to contain a length of track that is completely isolated from the rest of the layout, and fed power only through the reverse unit controller (AR1). Make that isolated section longer than your longest train if you can.

You should read my other thread about "Digitrax AR1"
It might help

Thanks, Guys! Looks like I was isolating only one side of the loop! Thanks again!!!

Sorry to trouble everyone but I can't seem to figure this out. I'm including a diagram of how I have this loop wired. Also including an actual pic of the tracks.

I do NOT have any toggle switches installed. In past layouts, my train would run until it hit the isolated track...at that point, I would flip the reverse switch on the transformer and it would continue.

Any advice would be appreciated!

A Digitrax AR1 would solve the problem. It's easy to install and about $25.
I have another thread about it about 17 threads down from this one on the 1st page.
I have the same loop. I run DCC
The AR1 feeds the loop from power it gets from the main line. You'd run the power wires you have in the loop directly to the AR1's 2 loop outputs. The main line power would go to the AR1's power imputs.
