I need some help. I recently visited the club layout at The Antique Barn in Wilson, NC. It was a great layout. One of the gentleman in the club shared with me that the club had begun to switch all of their Peco Insulfrogs for Peco Electrofrogs because the insulfrogs were shorting out at the frog. I have always used Peco insulfrogs and I have no problems. The problems that I have ever been made aware of was that the contacts on the points need to be clean so that connect solidly with the stock rail. I had read the Allan Gartner’s article on wiring DCC and how one might have to bevel the rail leading to the frog point toward the insulated frog. I have not even had that problem with my insulfrogs. From my experience with Peco Insulfrogs, one only has to install the insulfrog as it is without any modification, as long as you feed power behind the points of the insulfrog. Please help this newbie with this perceived new issue.
The Peco ‘Insulfrog’ turnout may short out at the frog if metal wheels with ‘wide’ tires short the two rails where they converge at the tip of the frog. A ‘fix’ is to ‘paint’ the tip of the frog with some clear nail polish so it is insulated.
