Curvature of railroad tracks, measures the degree of curvature (i.e) by measuring the degrees between the two radii of a circle having the track as the arc length. The measure of curvature of a circular arc is known as the degree of curve. It can also be known as the degree of curvature. You can calculate the railroad degree of curve using this online Railroad Curve calculator. To calculate the degree of curve, just enter the known radius value and find the degree of curvature.
Railroad curve degree = 2 x arcsine x (50ft/250)
