I’m going step up on my soapbox here and I hope that I do not offend anyone. If I do, I apologize in advance. If you think you are going to be offended stop reading now. “N SCALE” and “N GAUGE” ARE NOT the same thing. Unfortunately the two terms have been interchanged for many years. “N SCALE” is a definition of size when compared to the prototype, N Scale is 1/160 of prototype. “N GAUGE” means NARROW GAUGE. Gauge is the distance between the inner sides of the heads of the two parallel rails that make up a single railway line and in the United States the Standard Gauge is 4 ft 8.5 in. Thus Narrow Gauge has a distance between the inner sides of rail heads that is less then standard gauge. You can have a Narrow Gauge N Scale railroad, and it would have items scaled to 1/160 the prototype and the distance between the rail heads of a single railway line would be less then the normal N Scale track. This would be expressed something like "Nn3" meaning N Scale (1/160 of the prototype) narrow gauge with the distance between the rail heads to be 3 scale feet (0.225 inches or 5.715 mm). I realize that this confusion was started many years ago by the manufactures and how they labeled N Scale items with the term N Gauge. It continues today by some of the manufactures. That does not make it right. Even some of the retailers advertise N GAUGE; but all of the other scales are stated HO Scale, O Scale, S Scale, etc. You see this in magazine ads and in online ads. Again that does not make it right. Frequently we see here on TrainBoard something like this, “I’m designing an N gauge layout." Okay, my first thought is he or she is doing a narrow gauge layout, and I wonder what Scale. Further reading I realize that he or she is talking about N SCALE standard gauge. I have lost count of the number of times I wanted to post a reply pointing out the error in the use of N Gauge for N Scale, but I bit my lip and fingers because the original poster most likely does not know the difference because he or she sees the terms used the wrong way all the time, and especially if he or she has a box full of N Scale model railroad equipment from the Wiz-Bang-Train Company and on the box it states “Authentic N Gauge Model Railroad.” I understand that the terminology can be confusing, N Scale and N Gauge, Switch and Turnout and Switch just to name a few. Scale and Gauge are not the same so STOP using them as the same. I now climb down from my soapbox.
