I was thinking of: The reason to keep actual content only on pages with the new names is so that the Wiki keeps current game info. The reason to keep notes about the old names is obvious. Redirects, ditto.
 * 1) Create new set pages, copying-and-pasting the old onto the new.
 * 2) Change old set pages to redirect pages.
 * 3) Make note on new pages of old name.
 * 4) On Loco and Wagon pages, change links to new names. Add notes about old names.
