to the HO 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.
Scale is Half of O Scale)
