WP:OVERLINKING policy on Wikipedia:Generally, a link should appear only once in an article, but if helpful for readers, links may be repeated in infoboxes, tables, image captions, footnotes, and at the first occurrence after the lead. If an article of 1,000 lines has a link repeated on line 600 there is no objection to keep te second link. A link repeated three times in the same paragraph is just plain overkill. Any undesirable future edits (removal of templates) should be adressed by closely monitoring your watchlist, not placing an excessive amount of duplicate links.
 ...is to keep everything in a format that is uniform with everything... In my opinion, that's just impossible. Imperial versus metric, inch versus foot and inch, alphabetic versus historical order, etc. Using other units for Railgauge templates than its corresponding categories and article titles makes it harder to recognise a particular Railgauge when editing or reading text, especially for people accustomed to metric systems. When the list of track gauges, navbox track gauges, article titles and categories all mention 3ft 6in it is odd to use the devious 42in RailGauge template. Moreover, the Railgauge templates are only for conversion purposes and not intended for sorting lists by size or alphabet. Uniformity for the sake of uniformity serves no purpose.
Taking WP:NPOV, in particular WP:BALASPS in consideration, Rail transport in Disney Parks is not less or more significant than a randomly chosen rapid transit rail system, famous heritage railway, abandoned railway or extensively used common carrier railway. There are numerous other railways transporting huge numbers of passengers, preserving steam locomotives or having other notable features. And these aren't listed in the ""see also"" section either. I chose the ""spamming"" qualification for all your linking behaviour, not only the Disneyland links (see the section header).  "
