Dan, Good point. Most of my frog rails are very short, on turnout kits, or non existent, on cast frogs. There are ways to provide for a dead section before the frog (see the "FastTracks" site) that eliminate both shorting and derailments, but they are not simple, IMO, and eat up more track space. Roger

I did forget to pass on one helpful hint, learned through personal experience. If you are going to power-route the frog, minimize the length of rail that is powered by the frog. On some of my power-routed turnouts, for convenience, I have inserted insulated rail joiners at the ends of the two rails extending out from the frog. This technique provides the proper insulation for wiring the turnout, but it extends the "frog zone" several inches out past the physical frog. In this case, it is very easy for a locomotive approaching the turnout set against it to create a short long before the engine reaches the frog.
