Question re 3-1/2" & 4 3/4" gauge garden locos?

[RobertInOntario]

Robert,
1/2" gauge track: The scale would be 1:113, if it is "standard gauge", 1:72, if it is 3' narrow gauge.

4-3/4" gauge track: The scale would be 1:11.9 if it is "standard gauge", 1:7.58, if it is 3' narrow gauge.

I think 1:113, is close to TT scale( 1:120 ? correct me if I'm wrong ) ----- 1/11.9, about twice the size of G scale. There might, be something in those scales, with electric motors, but none that I've ever heard of ( except that TT scale is still "somewhat available", "somewhere" ).

So sorry -- that was a typo on my part! It should have read 3-1/2" & 4-3/4" gauge track!! Apologies for this confusion but thanks for your feedback!
