Editing Template:LocoTypeInfobox

<noinclude>
== Template:LocoTypeInfobox ==
Infobox for Loco Type category pages. A single template handles both steam and non-steam
variants — the <code>loco_category</code> parameter drives the color scheme and controls
whether the Wheel Arrangement field renders as a navigational link (steam) or plain
descriptive text (non-steam).

Requires: ParserFunctions extension (ships with MediaWiki 1.39, enabled by default).
Does NOT require the Variables extension.

=== Usage ===
<pre>
{{LocoTypeInfobox
| loco_category      = 
| wheel_arr          = 
| proto_manufacturer = 
| era                = 
}}
</pre>

=== Parameters ===
{| class="wikitable"
! Parameter !! Description !! Values !! If Empty
|-
| <code>loco_category</code> || Drives color scheme and steam/non-steam behavior. Linked to Loco Category page (displayed as "[Value] Locomotives"). || Steam / Diesel / Electric / Other || —
|-
| <code>wheel_arr</code> || Steam: linked to Wheel Arrangement category page. Non-steam: plain descriptive text, no link. || e.g. 4-6-2, B-B || —
|-
| <code>proto_manufacturer</code> || Prototype builder. Non-steam: linked to Proto Mfg category page. Steam: plain text, informational only — no category tag. || e.g. EMD, GE, Baldwin || —
|-
| <code>era</code> || Years the prototype was in active production or primary service. Drawn from the Prototype Era column of the Loco Types sheet. || e.g. 1945–1949, 1918–1960s || —
|}

=== Parameter Values ===
The <code>loco_category</code> parameter uses the SHORT form (no "Locomotives" suffix).
The template constructs the full category page name and display text internally.

{| class="wikitable"
! Spreadsheet value !! Category page linked !! Display text
|-
| <code>Steam</code> || [[:Category:Steam Locomotives]] || Steam Locomotives
|-
| <code>Diesel</code> || [[:Category:Diesel Locomotives]] || Diesel Locomotives
|-
| <code>Electric</code> || [[:Category:Electric Locomotives]] || Electric Locomotives
|-
| <code>Other</code> || [[:Category:Other Locomotives]] || Other Locomotives
|}

=== Steam vs Non-Steam Behavior ===
{| class="wikitable"
! Field !! Non-Steam (Diesel / Electric / Other) !! Steam
|-
| Wheel Arr. || Plain text — no link || Linked to Wheel Arrangement category page
|-
| Proto. Manufacturer || Linked to [[:Category:[Name] Locomotives]] || Plain text — informational only, no category tag
|-
| Color scheme || Gray / Amber / Navy (by loco_category) || Burgundy
|}

=== Color Reference ===
Colors are applied automatically via the short-form loco_category value. Do not set manually.
