Here is the OP's track diagram.

This is a classic reverse loop where the track folds back onto itself.  That divergent leg of the right hand turnout is the trouble spot where there is a reverse polarity issue.
 

OK what we are looking at is a layout, but where is the problem. The problem is not really in the loop, as that is actually the main line. Apply you main power to the loop and not to the yard on the left.

You make your gaps on all four rails to the right of that switch. Allow the position of the switch to select where that part of the railroad gets its power from.

It is really no different from my layout.

LION, that is the problem.

Without the gaps that you mentioned, the loco will cause a short as it completes the loop due to reverse polarity.

He might be indicating to make the reversing section the yard. The polarity would be reversed as the loco hit the switch. I was confused at first also, but although i would wire the main, Lions suggestion would work

I guess many of us figured that when the OP stated the problem section was running diagonal. 
What happened to or OP anyway?   Has this problem been solved.

Hi TZ.

Yeah, the problem has been solved and the OP has ordered a DIgitrax AR-1.  Once he mailed the track diagram off line to me, we exchanged emails discussing the problem and resolved it in that manner. With the OP's permission, I posted the track diagram for others to see.

Received the AR-1 today, and hooked it up.  Success!  Thanks to all for their thoughts and advice.
