I don't disagree. But the problem is whoever design O-gauge in the first place made the annoying decision to use 60 Hz. Transformers are just too big at such low frequencies. I think the hit must be taken to convert to DC, then use a switchmode isolated converter running at 1 MHz (or whatever) so that the inductors/transformers can be proportionally down-sized.
