What is it about?
The chord method is used for the horizontal and vertical versine measurements of rails. In this study, the horizontal versines of the left and right rails were precisely calculated, and the vertical versine functions were exactly derived.

Why is it important?
According to the inferences, the line charts used for determining the vertical versine were created to demonstrate the proportional relationship with the grade difference and the curve length. The equations for proximate vertical versine calculations were therefore derived. The asymmetrical chord measurements were introduced as well.
