Five ways you can tell you are in Melbourne, not Sydney

Part One: Level Crossings
Suburban railway "level crossings" don't exist in Sydney (maybe there are one or two?). There is always a road overpass or underpass. They remain very much part of the Melbourne suburban landscape. Bells and lights start, the boom gates come down, and the pedestrian gates across the tracks close automatically.

Apparently Melbourne stopped its program of replacing level crossings in the early 1970s, to divert money to construction of the Eastern Freeway.
