Background
The angle formed by the switch point, called the frog angle, is large and small. The switch number (N) represents the number of switch.
The main dimensions of the individual portions of the switch are usually expressed in the value of the cotangent of the frog angle (α), i.e., N ═ cot α ═ FE/AE. Switch angle of No. 9 turnout 6 degrees 20 '25'; switch angle 4 ° 45' 49 "of switch 12; the switch angle of No. 18 turnout is 3 degrees 10' 47.39 ".
