track radius

[SteamGene]

I know I should know this and I could measure it myself, but is track radius taken from the inside raid, the outside rail, or the center line?

I believe center line.

It's the "I believe" that is the sticker.

Gene,

Centerline, no question about it!

I agree, center line.

I usually measure the inside and outside rails, add them up and divide by two. Centerline is correct.

Ben,
I assume ypu count sheep by counting the legs and dividing by four, right? 
Center line was what I thought.  But I really needed to make sure.  Thanks, guys.   BTW, Sheldon, that means some straight track has been laid.
