Some reasons: -To make your turnout more short resistant (also called DCC friendly), which makes each point the same polarity as the stock rail. This also allows you to place the open point closer to the stock rail, which look better. -Unless you are using the points to route power through the frog and the rail beyond, you will need gaps someplace on the rails beyond. (An insulated rail joiner is just another form of a gap.) -If you are using stub turnouts, you have to isolate the frog(s), since there are no points. -If you need to make a crossing, unless you need to isolate two of the four crossings.

I understand that you want to do it, but in reality it is not mandatory. Maybe not isolating the frogs is an easier solution to your problem -- whatever the problem might be. What exactly is the reason for wanting to isolate the frogs in the first place? Curious....Ed L. > One thing that plagued me on the previous layout was my inability to isolate frogs. > Jeffrey Ngowe ------------------------------------ Yahoo!
