If the template has a separate documentation page (usually called "Template:template name/doc"), add
[[Category:Rail transport external link citation templates]]
to the <includeonly> section at the bottom of that page. Otherwise, add
<noinclude>[[Category:Rail transport external link citation templates]]</noinclude>
to the end of the template code, making sure it starts on the same line as the code's last character.
The requirement for templates such as these stemmed from the sudden move of an important reference website, used as reference citations in a multitude of articles, to a different host. For a template example, see Template:Garratt Builders B
