This is from George Hilton's excellent book, American Narrow Gauge Railroads:
Degrees of curvature is the number of degrees of a circle subtended by a chord of 100 feet.
A few years ago, I dusted off my old Trig textbook and figured that the 20 degree curves on the Cumbres and Toltec worked out to a radius of about 300 feet.
