Gary:
Can I suggest a way around the short on the frog? If the frog power is by a DPDT switch (of whatever form), the second pole can be used to selectively power the rails beyond the frog. A length of each rail long enough to contain a loco or consist is insulated beyond the frog and from the frog. This is power by connecting the frog wire to the center pin of the DPDT and connecting the outer pins to the new insulated rails. This will give a dead rail when the turnout is against it.
It also stops the train clear of the turnout.
