      HI David,
      I worked in Nn3 for a while and all in all, it's pretty close to actual "scale parameters" modeling...
      (turnouts hand-built with code 40 or code 30 rail, etc) but even then, there are always fudge
      factors to up with put. Hand building track and turnouts is very time consuming but it's fun
      once you've collimated all the adjustments that make the layout operational.

      I agree: To do similar "fine-scale" modeling in Z scale would require the resources
      of a Swiss watchmaker and a layout built and operating in an Intel "clean room".
      Even now, accumulations of dust and dander adversely affect my "off-the-shelf"
      Z scale operations. And I can't imagine building code 20 track and turnouts!

      Your new design for a Z scale coupler looks very promising and I wish you the
      greatest success in manufacturing this elegant solution to our coupling & de-coupling woes.

      Viva the innovator!

For it to function, however, the trackwork must be nothing less than absolutely perfect, and the cars weighted well above standard practice. Sprung trucks and drivers are also a necessity. By this time, costs would be astronomical--over a hundred dollars per wheelset; a few hundred for one truck; perhaps a thousand for one car, and the track--I cannot even imagine it. In the end, though, for someone with bottomless pockets, completely accurate wheels and track are indeed feasible. Practical, however, they are not.
