This is a good thread on the subject.
Interestingly enough my PECO code 83 DCC Friendly turnouts are DCC Friendly except when I created a run arround track. I am using a set of PECO turnouts at each end. Each end of the run arround is a set of PECO turnouts enabling the loco to cross from one track to the other, a crossover arrangement.
All the DCC equipped loco's work great except for one type, my great running Athearn SW1500's (new version). They stall short as they move from one turnout and start to enter the second turnout of the cross over. This happens at both ends of the run arround.
I tryed painting a part of the track where I thought the width of the wheel was creating a short. This did not resolve the issue. How can I combine isolating frogs and sections of rail to enable the SW1500's to run without shorting out? Why is it that it is just the Athearn SW 1500's?
