Template:RoadNameInfobox

Template:RoadNameInfobox

Infobox for Road Name category pages. Navy color scheme throughout — no color switching needed since all road name pages use navy.

The road name logo is integrated into the infobox header. The template automatically constructs the filename from the road_name parameter. If the logo file does not exist, the road name is displayed as a text label instead.

The successor field has been removed from the infobox. Predecessor/successor relationships are now displayed exclusively in the See Also section of the page as a visual railroad chain diagram.

Requires: ParserFunctions extension + $wgPFEnableStringFunctions = true (for #replace to construct logo filename from road_name).

Usage

{{RoadNameInfobox
| road_name         = 
| country           = 
| region            = 
| operational_dates = 
| rr_class          = 
| reporting_marks   = 
}}

Parameters

Parameter	Description	If Empty
road_name	Full road name. Used to construct the logo filename automatically.	(no logo or label shown)
country	Country of operation e.g. United States	—
region	Geographic area served e.g. Northeast and Midwest	—
operational_dates	Founded → abandoned or merged e.g. 1846–1968	—
rr_class	Class I, Class II, or Class III	—
reporting_marks	Official reporting mark abbreviation e.g. PRR	—

Notes

• Logo filename is constructed automatically as File:Logo-[Road-Name].svg

 with spaces replaced by hyphens. No logo parameter is needed.

• When no logo file exists, a styled placeholder is shown inside the infobox header —

 a dashed-border box containing the road name in bold and an "add one" prompt linking
 to the contributing guide. This placeholder is self-contained within this template.

• The successor field has been removed. Predecessor and successor relationships are

 handled entirely by the visual railroad chain in the See Also section, driven by
 the predecessor and successor parameters of the page scaffold template.

• All empty fields display —.
