This is a proposed subtemplate of TrainsWikiProject to handle a collapsed section for the associated projects and task forces
 * colspan="" |

To do:
 * add the rest of the associated projects and task forces
 * ensure that the various "... articles with comments" categories are used
 * ensure that the various "... infobox needed", "... map needed" and "... image needed" categories are used
