Half O
The designation HO stands for “Half O”. Of course if it was actually one-half of O scale it would be 1/96th, but because HO is actually a metric based scale and O is based on English units of measure the fractions become awkward. The model railroading industry says HO is “approximately half O”. N Scale – 1:160.
What is Z gauge 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 is HO scale in MM?
3.5 mm
HO or H0 is a rail transport modelling scale using a 1:87 scale (3.5 mm to 1 foot). It is the most popular scale of model railway in the world. The rails are spaced 16.5 mm (0.650 in) apart for modelling 1,435 mm (4 ft 81⁄2 in) standard gauge tracks and trains in HO.
What is the difference between O gauge and HO?
For starters, HO and O are completely different scales. HO is 1:87, while in the U.S. O scale is 1:48. I believe it is 1:43 in Europe. Lionel trains are not built to scale (they are essentially toys), though they run on O gauge track.
What is the difference between HO scale and N scale?
N scale is approximately half the size of HO scale. Since that size goes in all directions, an N scale layout takes up approximately 1/4 the space of a comparable HO scale layout. And if you like long trains, you can run longer trains in N scale than HO scale in the same space.
What size is TT scale?
| TT Scale | |
|---|---|
| Scale | 1⁄10 inch to 1 foot |
| Scale ratio | 1:120 |
| Standard(s) | NEM, NMRA |
| Model gauge | 12 mm (0.472 in) |
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.
What is the difference between O scale and HO scale?
What is the difference between N scale and HO scale?
Model railways come a variety different scales representing different sizes of trains and scenery. N scale is 1/160 scale. This means HO scale is 87 times smaller than the real prototype, and N scale is half the size of HO scale.
