Editing Template:RoadNameInfobox

<noinclude>
== 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 <code>road_name</code> parameter. If the logo file does
not exist, the road name is displayed as a text label instead.

The <code>successor</code> 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 + <code>$wgPFEnableStringFunctions = true</code>
(for <code>#replace</code> to construct logo filename from road_name).

=== Usage ===
<pre>
{{RoadNameInfobox
| road_name         = 
| country           = 
| region            = 
| operational_dates = 
| rr_class          = 
| reporting_marks   = 
}}
</pre>

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

=== Notes ===
* Logo filename is constructed automatically as <code>File:Logo-[Road-Name].svg</code>
  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 —.

=== Color Reference ===
Navy throughout — no switching needed.
