F is 1:20.3. Using the 20.3 scale ratio, #1 gauge track becomes 3' gauge which is why his models are Fn3.
The large scale scale/gauge issue can be confusing if you really don't understand the difference between scale and gauge. #1 gauge track is used with: 1:32 - Correct for standard gauge (Note twice S scale or 3/8"=1') 1:29 - Commonly used for standard gauge models but track gauge is 51". 1:24 - Correct for 42" gauge (1/2"=1') 1:22.5 - Correct for meter gauge 1:20.3 - Correct for 3' gauge 1:13.7 - Correct for 2' gauge (7/8"=1') There are also some models, especially of standard gauge equipment that actually work out to other scales in between. If you read Garden Railways, you will know what I mean. Several manufacturers seem now committed to making their models of 3' gauge equipment in the correct 20.3 ratio now so it's becoming more normal although older models are still to other ratios. I've seen this layout in person and it is impressive. His live steam railroad outside is really just as impressive and all this stuff is in his back yard. And he even has a Flyer layout on the mezzanine.

Neat Bill, Thanks for sharing. Maybe I missed but what is F scale. Never heard of it. cheers
