Re: Peco Electrofrog - Adding Gaps

A lot of people throw the term "gap" out there with no explanation as what they mean which, leads to a lot of misunderstanding. Is the rail being cut?. or are insulators being used?. An explanation of actually what is being done would stop a lot of confusion and cost to the person who is not wise to where the rail can actually can be cut without a disaster, such as the small rail sections falling out in a persons hand when the cut is made.. Just a thought, a lot of great information on this site. Bill Teeters Chicago,Peoria and Western RR. As seen on the site, Located Rockford, Ill.

Stub ended sidings where you're feeding power from the switch point end will not require that gapping.

If the siding is only a single industry, where no locomotives will be operating, you are correct. But if it is  situation where a locomotive will be spotting cars while the turnout is aligned the other way, as in a multi-spot industry, or a short branch into an industrial park,  a condition where both rails are the same polarity (phase, in DCC) will occur, if you don't isolate the frog.
As you noted, using the concepts of DCC friendly turnout wiring is best, even if you are not using DCC, Also, I would wire (and gap) every turnout to these standards, whether necessary or not. When it comes to model railroad wiring, standardization,  consistency, and documentation  in you wiring practices will benefit you down the road, when you find yourself troubleshooting a problem!__
