I don't get it...

The support spines under the actual rails.

Is someone trying to build another backyard coaster/s? Let us in on why you need to know.

Dude, you're getting an Intamin!

The spine of a piece of track is like what Colonel Sanders said, it is what the cross ties are connected to. Here is a picture of the spine on Magnum XL 200 at Cedar Point:http://www.joyrides.com/cedar_point/full/magnum5.htm

The running rails are the "tubes" or "pipes" of steel that the roller coaster's wheels run on. No, I'm not trying to build my own coaster, I'm just interested.

Hmm... this should help. This is A.I.R. at Alton Towers track.

I prefer the pears in the heavy syrup. They're just good.

Spines vary alot. Running rails are usually 4-5" diameter.
18" & 5" for Arrow/Vekoma.
