Abstract

Analytical expressions are deduced to calculate the deflection between a chord and a lemniscate curve. In railways, the interest of these expressions is that lemniscates are used as transfer curves between a straight and a circular section. Moreover, according to the regulations, the deflection that separates a wagon from the track must not exceed a certain amount, so that the expressions deduced are very useful in routine checks of railway tracks.
