to the HOn3 Page."HO"
indicates we are modeling in HO-scale
which in North America is a ratio
of 1 to 87 or 1:87 or 1 foot in
the model equals 87 feet in the
real world. HO-scale trains run
on 16.5 millimeters track. Standard
gauge track in the real world is
4ft 8.5 inches between the rails.
So in HO-Scale standard gauge track
is represented by 16.5 millimeters
track or 16.5 millimeters between
the rails. The second letter, "n"
indicates that instead of standard
gauge we are modeling narrow gauge.
The could be anything from 18 inches
between the rails to 42 inches between
the rails. "3" indicates
that in fact we are modeling in
HO-scale railroads that ran on track
which was 3 feet between the rails.
