Over the years the HO scale has become the most popular model train scale and the manufacturers have responded to the demand by producing more accessories and rolling stock for HO scale. HO scale is just the right size for most people to appreciate the detail and running performance without being too cramped.What are the different model train scales?
The most common model train scale is HO. HO trains have an approximate ratio to the original train of 1:87. Variations of the HO scale include narrower versions of the same scale, which means the trains are the same scale, but with less space between the tracks’ rails.What is TT scale model trains?
TT scale is a model railroading scale, whose name stands for t able t op. Its 1:120 scale (from a common engineering scale where one inch equals ten feet) and 12 mm ( 0.472 in) gauge are roughly halfway between HO scale (1:87) and N scale (1:160).What are the model railway scales?
From left to right, three different model railway scales: N gauge (2mm:1ft scale), OO gauge (4mm:1ft scale) and G scale . Gauge is the distance between the rails of the track in the scale chosen. Scale is the proportion of the model to the full-size item.
