Help!!!! Reverse loop nightmare

Hello all I’m stumped. I’ve tried a dcc specialties frog ar and a digitrax ar to see if I can get my loop to work. With the dcc specialties the train will get to the gaps and stop I’ve connected it correctly with the instructions with the jumpers. With the digitrax ar the train Will get through one gap but still sort out at the other where I marked on my diagram. I’m using an atlas s1 n scale sound decoder. All my switches are peco electro frog. Can any one tell me what I’m doing wrong with auto reversing that section of track.


Thanks for any suggestions

You might see if the following might apply to your situation...

Have you modified the Peco Electrofrogs to work with DCC? If you run the other direction, does the short occur at the other end of the loop?

 

Looks like you have 2 sections acting as a reverse loop.

 

No, you only have one reverse loop, as indicated by the non-bold line, between the two gaps.

However, more information is needed:

How long is the train are you testing with (relative to the distance between the two gaps), and do the cars have metal wheels?

Where are you feeding power to the non-reverse loop trackage (bold tracks)? And to the reverse loop (via the AR controller)?

 

What IronMan1963 circled are two sections fed by two turnouts each (actually, the second circle only marks one of the two turnouts). Depending on whether and how these turnouts route power, you might create a short if only one of the two turnouts feeding each track section is set for that section. Something worth checking. If your electrofrogs are unmodified, then I believe they short the point rails together and do create this problem. See https://dccwiki.com/PECO_Electrofrog

 

I can see how the turnouts could short the rails, but that would cause the loco to stop wherever it was when the switches were thrown such as to cause the short, not when the loco reached an end of the reversing section.

Unless the switch was thrown at the exact same time the loco reached an end of the reversing section...

Peco's definition of "power routing" is very different than Kato's (Unitrack). Kato switches do not ever short the point rails. The point rail for the selected route is powered, and the point rail for the unselected route is not powered.
