Turnout of Contrary Flexure

A turnout of contrary flexure (Fig. 15.2) is one that takes off towards the direction opposite to that of the main line curve. In this case, the degree and radius of the turnout curve are given by the following formulae:

Here Dm is the degree of the rail of the main track on which the crossing lies,

i.e., the outer rail in Fig. 15.2.
