For a variety of reasons, which I won't go into because it could take days, the scale of 1/29 exists on 45mm track. The track gauge is slightly too narrow to correctly model 4' 8 1/2" track.With 45mm track the correct scale/gauge combination is 45mm. I'm modeling in 1/29, but after spending a few years building my first layout I was never happy with the scale/gauge issue in 1/29. I kept hearing that it was not possible to regauge the 1/29 equipment to run on correctly scaled track. After some experimentation with USA Trains equipment I've discovered that it is possible to regauge 1/29 to the correct gauge without making major modifications. I haven't tried yet with other manufacturers so I'm not exactly sure.
Here's the numbers between 45mm gauge track and prototype track in 1/29 scale.
56.5" in 1/29 = 1.94827"
|45mm gauged wheel to the left, P:29 gauged on left.|
A difference of ~.177"
A lot of people don't care about this difference, but to me it's noticeable.

Yes I won't have the option to bring my locomotives, or have a visitor run their 45mm gauge locomotive on my layout but I can live with it. I wouldn't ask a HO modeler who models the 1930's steam era if I could run my modern locomotives during their operating session. So why expect/demand it in large scale?
