Well after trying to run some double headed power with a train around the reverse loop, I was still having intermittent problems with a short in the location where the turnout off the main leads into the short section of track and the crossing for the interchange track. If I ran the locomotives uncoupled but, still consisted, there was no problem and then sometimes with them coupled there were no problems. I thought maybe a short through the couplers and the locomotive frames may have been a possibility. There were no problems with a single four axle unit or six axle unit running through. With more discussion with a friend, it was determined that there was just to much going on in that area and the DCC Specialists auto reverser couldn't keep up with it all, plus the transition from the turnout to the crossing isn't the most favorable one. This makes a case for me to learn how to make a hand laid crossing here sometime in the future with the correct angle to further smooth out the transition. It was kind of tough to get that short little section of track to curve the way it needed to. After the discussion, it was decided to move the insulated gap from the turnout just off the main to just before the open ended turn out a few feet from the crossing. With fingers crossed, the move was made. The picture below shows the change. The red circle was the old location for the gap and the yellow circle shows the new location for the gap.
