What is the smallest model railway gauge?

Updated on April 17, 2026
T gauge (1:450 or 1:480) is a model railway scale with a track gauge of 3 mm (0.118 in), referred from "Three-millimeter gauge" or "Third of N scale". It was introduced at the Tokyo Toy Show in 2006 by KK Eishindo of Japan, and went on sale in 2007. It is the smallest commercial model train scale in the world.
.
Moreover, what size is N gauge model railway?
N scale is a popular model railway scale. Depending upon the manufacturer (or country), the scale ranges from 1∶148 to 1∶160. In all cases, the gauge (the distance between the rails) is 9 mm or 0.354 in.
Beside above, what is the smallest radius for N gauge track? Length of Your Train
| Modeling Scale | Minimum Radius |
|---|---|
| Z Scale | 7.6 inches or 195 millimeters |
| N Scale | 9 3/4 inches |
| HO Scale | 15 to 22 inches |
| HOn3 Scale | 15 inches (narrow gauge) |
In this manner, what is the best model train gauge?
With a track gauge of 16.5 mm and a scale of 1:87, HO is the most common model train size today.
Which is better HO or N scale?
An advantage of N scale is that it allows hobbyists to build layouts that take up less space than HO scale, or put longer track runs into the same amount of space, because the models are smaller (by nearly a half) than they are in HO scale (1∶87).
Related Question AnswersIs N Scale cheaper than Ho?
You can get started in either one inexpensively, but N scale is cheaper than HO scale. That said, the trains are the cheaper element. An N scale layout is no cheaper than a comparable sized HO layout. N scale trains cost less than HO scale, but used HO scale trains are cheaper than new N scale.What size is N gauge?
N scale is a popular model railway scale. Depending upon the manufacturer (or country), the scale ranges from 1∶148 to 1∶160. In all cases, the gauge (the distance between the rails) is 9 mm or 0.354 in.How big is Z scale?
Z scale is one of the smallest commercially available model railway scales (1:220), with a track gauge of 6.5 mm / 0.256 in. Introduced by Märklin in 1972, Z scale trains operate on 0–10 volts DC and offer the same operating characteristics as all other two-rail, direct-current, analog model railways.What size is O gauge?
Various sizes of track gauge exist around the world and the normal O gauge track represents the Standard gauge of 1,435 mm (4 ft 8 1⁄2 in). "O gauge" refers to tracks that are 1.25 in (31.75 mm) apart.What are the different model railway gauges?

What is the largest model train size?
With a track gauge of 16.5 mm and a scale of 1:87, HO is the most common model train size today. Lionel has manufactured HO trains several times in its history. Today, we offer The Polar Express™ locomotive and train cars.What is the difference between N scale and Z scale?
The Z scale trains are model trains that have a scale of 1:220. That makes them smaller than the N scale, but not by a very high margin (N scale is about 1:160). You get to use a lot more space for the landscape itself, yet at the same time, the trains are visually appealing and super detailed despite their size.What gauge is Lionel FasTrack?
