Gentleman,I have been in this hobby for over 50 years and have been in HO. O and S. And have never isolated a frog. All you have to do is cut the frog at the exit end both inner rails and let the wing rail do their job. of suppling power and polarity is not a problem. I am now using DCC in O scale using same methods.You isolate the frog and you end up with a 2 to 3 inch dead spot that you will have to power some way. Thanks Bert Cutler

If you don't isolate on the point side, you would have to either rely on point contact to switch the polarity of the point rails or you would need to install a switch. I don't power my frogs, so isolation is mandatory to prevent a short. After isolating the frog, I install non-switched drops to the point rails. I find this set-up very reliable without wiring switches to the frogs and have had no trouble even with short wheelbase 4 wheel locos powered by a Black Beetle.
