Wording confuses gauge and scale, I think. Again. 10mil (UK only) and
1:32 are for modelling standard gauge (4' 8.5") on gauge 1 (45mm) track.
This has definitely become a minority interest.
Most people now use 1 (45mm) for several narrow gauges, the most common
being meter gage (1:22) and 3ft gauge (1:20.3). For both these scales,
1:24 is usual for buildings, figures, vehicles, etc. Nice mish mash, but
the 6ft rule ("usual viewing distance") shows that the differences in
scale aren't noticeable. Also, because of the large variation in
clearance diagrams for narrow gauges, running meter gauge and 3ft gauge
or even 2ft gauge stock together doesn't offend the eye at all.
OTOH, Aristocraft and USA Trains make 1:29 scale standard gauge trains
for 45mm track. Why? Because 1:32 trains don't look bulky enough next to
narrow gauge stock. And the largest market is garden railways, whose
operators want standard gauge trains to look bigger....
Then there's Thomas, whose scale is indefinable. ;-) But he looks good
running on 45mm track.
