Dale has a question for experienced model railroaders and asks:

“Curve Radius – 15″ 18″ 22″ Is this radius measured from the inside of the curve; the center line of the curve; or, the outside of the curve? Does someone know?”

Dale,
The Radius is measured at the CENTER LINE of the curve, Just as it is when spacing multipule tracks for a multi track line or yard.
