- This is UK (and European) practice. TT had a surge of interest in the US
- during the early 1950s; Kemtron and Dance were among the suppliers. This
- used the scale of 1/10" = 1 foot. The model track gauge was 0.471"
- (1/10" is a ratio of 1/120). The "TT" was alleged to stand for
- "Table Top" as very small alyouts could be built.
-
- I'm not aware of anyone modeling in TT in the US at this time.
-
- Also the comment that "00 uses the same track gauge as H0" is only
- true for UK. US 00 gauge is wider than H0 - 3/4", and a scale of
- 5/32" = 1 foot has been often used. This is a tad smaller than
- the 4.0 mm scale also used - 3.97 mm.
-
- 00 remains an active scale in the US, albeit used by a mere
- handful of modelers.
