Each level-crossing removal in Melbourne has unique challenges and opportunities. The Bell-to-Moreland project on the Upfield line, for example, involves removing four level crossings and building two new train stations. To remove the crossings, the rail has been elevated to create “sky rail” over a 3km stretch. The land below can then be re-purposed for linear parks, recreation and active transport such as walking and cycling. While the government emphasises such uses, these appear to be incidental reasons for the project. “Level-crossing removal” rather than, say, “rail upgrade” or “linear park project”, suggests its main purpose is to ease traffic congestion.
