[Accrs-o] O Scale Dimensions

[ACCRS O Scale list]

I have a question on O scale measurements and wanted to check with others.


Conversion – what is the correct conversion for 2 Rail 1:48 scale.  I’ve seen it listed as 1:43.5


Using that then the spacing between rails for 4’ – 8.5” comes to 32.99 millimeters.   I don’t have any two rail O scale track here to check that.     Is that correct?    Using 1:48 comes to 29.90 millimeters.

Millimeters is what I want to sketch with.
