Peco Insulfrog Nscale Turnout Short?

"In Code 80 Insulfrog turnouts, some wheel treads may cause an electrical short on the insulated frog unless the heel rails of the frog are isolated with insulated rail joiners.", excerpt from <!-- m --><a class="postlink" href="http://www.awrr.com/PECO.html">http://www.awrr.com/PECO.html</a><!-- m -->

Bingo! I would bet money that this is my problem. I will check which cars seem to cause this problem, but so far I think it's only some of the larger diesels and passenger cars. I can definitely look into replacing the larger wheels on the passenger cars with a more narrow wheel. As long as the car is only momentarily on that area, the short is - well - short lived. But if I stop a car and it rests on that particular problem spot, I can always expect a short to occur long enough to affect the entire system, sometimes so much that all trains receive a signal to run at a high speed. I've had several derailments and crashes caused by this short problem and my railroad board of LPPs have threatened to file suit or strike unless I correct the situation and improve the safety on the line.


Thanks for the tips guys!
