Any time you have a "crossover or a run-around" with the frog ends facing each other, you are completing a reverse loop, that requires insulating the turnout with a AR1 Reverse module to prevent a short circuit. The use of "double slip switches" will prevent shorts. Bob Hahn

Thanks for the suggestion. I will go ahead and do that. I will inform this forum thread when this issue is resolved.

     What Should I do to remedy the issue regarding the opposing turnout? Do I need an autoreverser? In the meanwhile I will simply remove the turnout with only one insulated frog.

I believe the solution is to isolate the frog of the lower turnout by cutting gaps in the stock rails that diverge from that frog (use a Dremel or a saw).  Make sure the turnouts are fed power from their point sides and not the frog sides.

what happens when you set the turnout correctly?

Your opposing turnout in the crossover is set for the tangent and against the turnout approached by the AEM.  Have you tried it set for the diverging route?

PS.  It appears that one frog is insulated and the other is not.

Every locomotive I have does that. My locomotives does this at the switches shown in the video.

So to confirm, this loco and no other has the problem, all your other locomotives work fine on the switches?

Does this loco do this on all the switches?

     This is a video above is to give you the overall detail of my layout. The video below will show you that everytime I move the SEPTA AEM locomotive over the turnouts it stalls and causes a short circuit. Turn up your pc volume and you will hear a beep comming from my Digitrax DB150.

The video bellow is the same but shows a different section of the layout.


?action=view&current=0c53e486.mp4


     What should I do to eliminate this? Do I need an automatic reverser? Im troubleshooting this issue so far I see no obstacle in the wiring that would cause any short circuit.


The picture below is a normal diagram of my layout. Note that the red markings that you see in the middle and lower left of the diagram are not grade crossings but ate actually grade separated overpasses. They should not be mistaken for crossovers with wire feeders.

The diagram below shows the short circuit in detail and feeder wires in red.
