I'm assuming that the Peco turnouts do essentially the same thing ... correct? :? :?:

Pretty much. Peco turnouts also have extra power contact points on the point rails that slide up under the stock rails and give you another power contact point besides just the points themselves.     With the insulated frog version, even though they are power routing by design, you have power coming into all rails on the turnout all the time, unless you deliberately insulate them from the other tracks. About once a year, I'll spray some contact cleaner on the critical areas on the point rails just to keep everything nice and clean. In over 20 years of using Peco turnouts, I've never had a problem with one of them. They are extremely well made!
