One important caveat: Unless you literally REMOVE the center rail from your existing 3-rail track system, you should not expect reliable operation of 3-rail wheels and flanges through 2-rail O scale switches.
Unfortunately the way a lot of 3-rail O gauge locos are made, conforming the wheels to NMRA standard O scale geometry involves skilled and irreversible machine work. And that's a shame, because getting rid of the center rail could be a reason more folks would opt for battery on board.
