This time for sure!

I don't have tracks size memorized, but a few years back I sat down with
my new calculator and came up with some interesting numbers.  At that time,
these were the "popular" scales:

        O       1:48    which is 33% larger than
        S       1:64    which is 36% larger than
        HO      1:87.1  which is 37.7% larger than
        TT      1:120   which is 33% larger than
        N       1:160   which is 37.5% larger than
        Z       1:220

The mathematical progression intrigued me, especially the fact that
alternating scales have large followings.  I extrapolated in upwards.
It seems 1:1 will never be one of the "biggies."

Now that I've made my point, here's what I think I know about some of the
others:

OOO          Early name for N
OO           1:72  Popular in England and Evanston, Illinois.
Q            Runs on O gauge track, but built to scale.  O gauge actually
             had wide track.  If you're ever in Chicago, go see the
             Museum of Science and Industry.
LGB
G
standard     made before WWII, mostly.
1            Larger than O
2            Larger than 1

        Happy Railroading!
