scale names

where do the scales get thier names?

"O" now pronounced oh was origionally Zero Gauge

"HO" half O At 3.5 mm = 1 ft, it is 1/2 the 7 mm = 1 ft scale that was commenly used with O Gauge track in England (other scale have been used fo O Gauge, The scale most often associated with O in the US today is 1/4" = 1 ft)

"N" Nine millimeter which is the gauge of the track

"OO" at 4 mm = 1 ft another half O scale

"OOO" Treble O roughly half the size of OO

"G" I believe that the track is actually number 1 Gauge, the "G" comes from the LGB company which introduced the popular line of outdoor electric trains.

S - three S ixteenths to the foot, one S ixty fourth scale, S even eights (original track gauge in inches).
TT - TableTop
Z - last letter in the alphabet for smallest scale

If I recall correctly, treble O is the original name for n-scale. I kind of like it.

I think you are correct, the first adds I saw were for OOO.
It came from England and ran on the same gauge track but is a slightly larger scale. All the early N scale stuff was from Gernany or maybe Austria.
