Excerpt from Railroad Curve Tables: Containing a Comprehensive Table of Functions of an One-Degree Curve, With Correction Quantities Giving Exact Values for Any Degree of Curve; Together With Various Other Tables and Formulas, Including Radii, Natural Sines, Cosines, Tangents, Cotangents

The correction quantities are original in that they are applicable to any function of a curve and are independent of the central angle. The rectangular co-ordinates X and Y, are believed to be entirely new. The appendix, Field Engineering Without a Field Book, is here presented for the first time.

The computations have been made with extreme care. The approximation of feet for the radius of a one degree curve, used in several previous books, has not been permitted in the preparation of the present volume.
