There is also a heavily-compressed version (as in, the coaches are like RMT Peeps) of a Series 0 or Series 100 Shinkansen made as a floor toy. It's almost sized for O Gauge.
I considered getting a pair of them (they're cheap) and outfitting them to run on 'O' track in a back-to-back configuration, like the prototype. But there is still that bugaboo about getting power trucks in 3-rail 'O'. I could probably fabricate something for the coaches, but the power cars are beyond my means to convert without spending a lot of dough. (well, much more than the trains cost anyway)
Addendum: Here's a goofy-looking Chinese toy bullet train. The coaches look like compressed copies of 027 coaches: https://www.youtube.com/watch?v=i3w2YXfUCfI
