The Melbourne suburban train network just after the City Loop opened in 1981. This is probably my favourite map of this particular network: it’s clean and graphically simple — black dots are all that are used to indicate parking, not a graphical vehicle icon or even a “P” in a circle. The colours are nice and bright and group the lines into operational groups quite neatly… an approach I prefer far more than the zone-based colours that Melbourne went to in the 1990s.

The vertical labels for Spencer Street and Parliament stations on the Loop are unfortunate and probably could have been avoided with a little more thought. The least successful element is probably the hollow dashed lines to indicate co-ordinated bus routes, which seem a little vague to be useful to the uninitiated. Regular commuters would probably get along just fine, however.
