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

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.

I'm afraid that some of us have been confused by
your post in a thread on a similar subject by Beepjuice.

We're always happy to do what we can to solve your
problems but it would be helpful if you would
start your own thread so as not to confuse your
problem with that of the original.

But, back to your situation.

You indicate that yours is a DC layout. There is a
automatic controller for DC reverse loops. You
can check it out here:

http://www.azatrax.com/model-railroad-reverse-loop.html

Without such you would need to have a separate power
to the isolated section controlled by a Double Pole Double
Throw (DPDT) switch. You would also need to use a
similar switch for your main track. When the loco
reaches the isolated section you would match polarity
using it's switch. When it then nears the main track
you would use the main track switch to again match polarity.

(the automatic controller does this for you)

Special thanks to Beepjuice and Don R for your help with this. I could swear that my last layout had a loop I was able to control by simply using the reverse switch on my Power Pac. Guess I'll have to install a DPDT switche to get this straightened out.

Also, please accept my apologies for any confusion I may have caused. Considering the original thread topic by Beepjuice, "This is a loop, right?", and the subsequent exchanges of information, I thought that my questions were relative to the conversation. Again, I'm sorry if I seemed to have hi-jacked the thread.
