I am trying to achieve a loop and the track keeps shorting out.  I have put a 9" Power Terminal with Insulated Gap track (I have opened the gaps underneath the track) - with and without power to it and when the locomotive goes across the gap track, it still shorts out (either direction). Any help to cure this would be appreciated.

I am a total rookie.  I have set up my HO layout and have made an inside  loop that shorts out.  I was told to pick up some auto reversing track to cure the problem.  This has done nothing.  How do you cure this??? Signed, Treno
