Dear David,
Why would we want to stay on topic?
1:24 house with a back yard LS (45mm gauge) layout:
Lets see, 45 mm times 1:24 = 1.9mm gauge track, or about 1/16". Code 14 rail.
Hmm. Might be a challenge. (To compare, N scale track gauge is 9 mm, code 80 rail)
1:13.5 x 1:24 = 1:324 scale
1:16.9 x 1:24 = 1:406 scale
1:20.3 x 1:24 = 1:487 scale
1:24 x 1:24 = 1:576 scale
1:29 x 1:24 = 1:696 scale
1:32 x 1:24 = 1:768 scale
A bit too small to be practical.
A 16" gauge kiddie ride (park) train is about 1:3 scale.
1:3 x 1:24 = 1:72, or somewhere between S (1:64) and OO (1:76 running on HO track).
Other riding scales:
1:8 scale x 1:24 = 1:192, very close to Z scale (1:200)
1:12 scale x 1:24 = 1:288.
Hope this helps.
Sincerely,
Joe Satnik
