Reply to "3-Rail Dual Gauge Track"

Why not go for DCC? DCC typically uses 19v AC. 

Run either the centre, or the common outer rail as one feed, the other as the return and let the O gauge only, outer rail look after itself. 

Regauge the On30 locomotives and stock to suit. I don’t know about in the USA, but O14 is a thing in the UK, with specialist trade support for 14mm Gauge axles and wheelsets.
