Many older N-scale models may not run well on Code 55 track as their flanges are often unrealistically large, causing the wheels to bounce along the ties instead of ride along the railhead. Wheelsets with these large flanges are colloquially known as 'pizza cutters' due to a resemblance to the kitchen utensil.

The terms N scale and N gauge are often inaccurately used interchangeably, as scale is defined as ratio or proportion of the model, and gauge only as a distance between rails. The scale 1:148 defines the rail-to-rail gauge equal to 9 mm exactly (at the cost of scale exactness), so when calculating the rail or track use 1:160 and for engines and car wheel base use 1:148.

The Clinchfield layout measured 6 by 13 feet (1.8 by 4.0 m) and was noteworthy for a number of reasons: 1) it was highly portable because of its modular construction, 2) it showed the potential of high scenery to track ratios possible in 1:160, 3) it used a unique aluminum frame and (at the time revolutionary)

All rails are spaced 9 mm apart but the height can differ. Rail height (in thousandths of an inch) is expressed as a "code": thus, Code 55 rails are 0.055 inches (1.4 mm) high while Code 80 rails have a height of 0.080 inches (2.0 mm). Common real railroad rails are at least 6 inches
