The total length of a crossover with entire curved leads and equal angles of crossing can be calculated using the formula $\sqrt{D (4R - 2G - D)}$, where D is the distance between the centers of two parallel tracks, R is the radius of the curve, and G is the gauge of the track. This formula accounts for the geometry of the curved paths connecting the tracks.

If D Is Distance Between Centres of Two Parallel Tracks D(4R−2G−D)\sqrt{D (4R - 2G - D)}D(4R−2G−D)​
