Points (turnouts or switches)


Points (U.K.) or switches (U.S.), technically known as turnouts, are the means of directing a train onto a diverging section of track, for example, a siding, a branch line, or a parallel running line. Laid similar to normal track, a point typically consists of a frog (common crossing), check rails and two switch rails. The switch rails may be moved left or right, under the control of the signalling system, to determine which path the train will follow.
