Many of these “ghost” tram routes run from the City into the suburbs, generally to tram depots. They could save you a long wait, but because almost nobody knows the numbers, they don’t get used. Years after they were highlighted in the media, they remain.
Renumbering them, for example to use a primary route number with a suffix (such as 86A, instead of the unknown 89), would make the tram system more useable.
Update: We understand Yarra Trams is working on this, and some on-board tram maps already use route numbers with suffixes to show short runs.
