Regarding circuit breakers, bring in the U.K. I have a two-stage reduction - 230v AC to 110v AC, then a KW to give 20v AC. I presently use a proprietary step-down transformer bought on eBay for the primary step-down, and I find that this will trip out before the KW; which I suppose, illustrates your point about modern electronics being more sensitive.
NOT fast enough for todays electronics!

Looks as though I’ve definitively settled on “no modern electronics” for O Gauge.
TBH, if I was interested to go down that route, I’d have just concentrated on On30. I already have two MMI 2-8-2s and the BLI 2-8-0 fitted with DCC and modern sound, requiring 36” minimum radius (=O72). The whole attraction of O Gauge was to be able to build layouts on doors, sound air whistles, back locos over uncoupler tracks that go “bzzz.. clunk” and the rest of it.
The solution is so so simple. Just add an inline fast blow fuse from the KW outputs.
