Uhm no...your picture shows the diameter of a circle. The 'radius' measured
from the middle of the circle to the track. IIRC the center of the track is
used when measuring the radius of train tracks).

Sorry for nitpicking, but the term radius doesn't come from 'half a circle'.
It is used to describe a circular path when a given point is turned X
degrees around a fixed point where the two points are the distance Y apart.
Y is the radius. Radius is a latin word which can be translated as 'the
spoke of a wheel'.
