Usage

{{Railway signal mast}} is a template for displaying signals on a mast for demonstration of railroad signalling aspects. It displays up to three signal heads using spotlight, one of two types of semaphore, or positional signals, along with a base and modifier plates.

{{Railway signal mast|top signal|second signal|bottom signal|plate=|type=|align=|size=}}

Signal indicators

A bare signal mast section is indicated with "x". Other indicators are dependent on the type parameter.

Type	Red	Yellow		Green		White	Other	Notes
Light	R	Y		G		W	blank space	Standard spotlight-style indicators. Lower-case letters indicate blinking lights.
Semaphore	R	Y		G			blank space	Modern upper-quadrant, 3-position semaphore signals.
Sema2	R		y	G	g		blank space	Lower-quadrant, 2-position semaphore signals. Upper-case letters indicate a main signalhead, while lower-case indicates an advance signalhead.
Positional	R —	Y /		G \|		W \	blank space	White light positional shield. "W" indicates the permissive aspect, while "Y" indicates the advance aspect.

base - Mast base chooser: Gantry, Base
plate - Plate modifier for the mast: Res, Yel, SPS, <none>
type - Signal type: semaphore, sema2, light
align - Diagram alignment: left, center, right
size - Scales diagram by percentage (do not use "%"): 100

Examples

Light mast (default)

Uses plate= parameter

{{Railway signal mast|W|y|G|plate=Yel}}
