OO is 4mm to the foot. 4mm.= approx .156 to a foot or 1/76 of full size. S is 3/16 to a foot., or 1/64th of full size. See chart below. There are some other scales used because, for example, O gauge comes out to be 5 track gauge using the figures below. This is corrected by some who use 17/64 per foot and 1 ¼ track gauge or .250/foot and 1 3/16 track gauge. Also, HO is sometimes called 1/87 scale and sometimes 3.5mm to the foot.
For this chart I used the value 1mm. = 0.0394. This is in Courier type and should reproduce the chart correctly.

I'm sure this has been answered but searching might be a morass for me! :-) . I have a friend in England who has Hornby OO stored away in the attic. tx for info Rance Velapoldi (Tranby, Norway) [Non-text portions of this message have been removed] [Non-text portions of this message have been removed] Yahoo!
