Scale/gauge query

Evening :-)

 

Apologies if this has been asked before but...

 

I model in OO standard gauge normally, am I right in thinking that if I wanted to represent a 2ft gauge railway in 4mm/ft scale it's OO-9 im looking for?

 

As a follow up, does anyone do a kit of the Funkey diesel Vale of Ffestiniog in that scale?

 

Cheers

 

Dan :-)

Actually it depends on how you measure it.

 

OO is 21/3 mm too narrow for standard gauge which scales to 7 inches.

 

OO9 is 1 mm too wide for 2 foot gauge, which scales to 3 inches.

 

So, yes 21/mm > 1mm

 

But by percentages of the gauge, OO9 is 12.5% too wide compared to what it should be.  By the same token however, OO is only 87.6% of what it should be - in other words, 12.4 % too narrow.

 

Although I've never met an engineer who would quibble very much about 0.1% diffference.
