Nope, not an item on my bucket list.
During my working career I rode Japan's Shinkansen many times. What a fantastic system, smooth ride, precision operation! I retired, though, before any of the European versions of hi-speed rail were available.
As for an O3R model, I find the whole idea a bit of a conundrum. The first time I scratched my head over this question was when Lionel released its model of the Acela.
The very functional nature and essence of this sort of train is when it is at it's design speed...very high speed! Most O3R layouts among the broader O3R market that I'm aware of do not have trackwork...i.e., broad curves... capable of accommodating this exceptional high speed operation. And, BTW, for this realm of equipment, O72/O84 are NOT broad curves!!! So, what's the point?
Of course, there is the aesthetical aspect of these high speed trains. But that could be appreciated in a model just sitting on a shelf, IMHO. Many of the photos we see of these trains that draw our admiration and awe are when the train is at rest, in a station, parked for a publicity shot, etc.. But it is, after all, the complete train that we're talking about, not just the lead unit. So buying just a lead unit 'shelf queen' of one of these marvels?......I think it would lose most of its 'chutzpah'. And spending that much money....much less finding sufficient linear shelf space!!!!...for a shelf queen train?......no thanks.
But, since you asked, that's just MHO...
