This is a tracking category, a category intended to build and maintain a list of pages primarily for the sake of the list itself. These categories are used to track, for example, pages using deprecated syntaxes, to maintain a list of pages that may need to be edited en masse later, or to aggregate the members of several sub-categories by other classifications into one larger list.
These pages are part of theAdministration of the TrainzWikibook project.This category holds various Trainz formatting template tools, which also assert one or more automatic categories on pages on which the are used. All are therefore typing aids as well.
