A right-hand railroad switch with point indicator pointing to right Animated diagram of a right-hand railroad switch. Rail track A divides into two: track B (the straight track) and track C (the diverging track); note that the green line represents direction of travel only, the black lines represent fixed portions of track, and the red lines depict the moving components.
The point clip clamps the end of a moving rail (the switch rail) of a set of points to its associated stock rail, and the scotch is a timber wedge used to ensure that the other moving rail is kept away from its associated stock rail. In this way the points are fixed in either the 'normal' or 'reverse' positions and cannot be moved by the usual ...
Train shunting puzzles, also often called railway shunting puzzles or railroad switching puzzles, are a type of puzzle. Shunting puzzles usually consist of a specific track layout, a set of initial conditions (typically the starting place of each item of rolling stock ), a defined goal (the finishing place of each rolling stock item), and rules ...
Interlocking is a safety measure designed to prevent signals and points/switches from being changed in an improper sequence. For example, interlocking would prevent a signal from being changed to indicate a diverging route, unless the corresponding points/switches had been changed first.
The wagons were guided by the pronounced flange on the wooden wheels, and the narrow gauge of 480 mm (18 + 7 ⁄ 8 in) allowed the points to be altered by swinging the single switch rail.

The Signal ID is WFP (Whisky Foxtrot Papa) 34 R with a Triangle (Delta) Plate to show that it is not a stop signal. This is only to show what a Fixed distant board looks like. Points at the entrance to a crossing loop are spring-loaded for the correct track for facing movements, and are pushed across by the wheels for trailing movements; they ...
