Two questions

1. When a track radius is mentioned for sectional track, were is the radius. Track center, inside rail, outside rai, other?

2. Explain rail code size. What is the normal sectional track code?

 Usually its the center line. AristoCraft has a downloadable track template - http://www.aristocraft.com/catalog/track/track_templete.pdf

Rail code is just the height of the rail in 1000ths on an inch. Code 100  is 100/1000 or 0.100 inches or 1/10 of an inch.

Regular large scale track is code 332 or about a third on an inch. Many finescale modelers use a shorter, more prototypical code 215 or 250 rail. I'm not one of them. Code 332 is sturdier and will take more abuse and foot traffic and the added height gives you more clearance to run over obstacles like acorn, rocks or twigs on the track.

 John has mentioned the approximate diameter of the track labelling system used by LGB track (and I think Piko too) though R5 is about 13.5 feet in diameter and R2 is about 5 feet D.

Important note: The "R1, R2, etc." nomenclature is manufacturer specific. There may be some overlap (for instance, both LGB and Piko's "R1" is 2' radius), but do not assume that one manufacturer's "R#" will be the same as anothers. ALWAYS find out what the actual radius/diameter is before ordering.
