Nearly all of these have been for track extensions of existing lines to connect with nearby railway station or to service new areas and suburbs.
[1] The 18 km (11.1 mi) extension would run from Caulfield station to Chadstone, Monash University, Waverley Park and Rowville.
[6] In 2021, Monash University began lobbying the state and federal governments for an alternative rapid bus plan, using experimental "trackless tram" technology.
[9] State and local governments have also proposed the extension of route 48 from its current terminus at Victoria Harbour in Docklands across the Yarra River and into the Fishermans Bend precinct, a future major urban renewal area.
The tram extension is proposed as an interim solution to connect Fishermans Bend residents to the CBD via mass transit until the metropolitan railway network can be extended with new underground stations.
[14] The 2019-2020 state budget allocated $4.5 million to plan the tram routes to Fishermans Bend and develop a preliminary business case for the project.
[16] It would run from its current terminus to East Malvern railway station, before continuing until it reaches Chadstone Shopping Centre.
[19] It would require an extra 2.2 km of track extending over the Monash Freeway, continuing along High Street until reaching the level crossing.
[20] In February 2018, the federal Opposition Leader Bill Shorten pledged $40 million to extend Route 11 to the end of Gilbert Road if the Labor party won government.
[29] In 2006, the Liberal opposition under Ted Baillieu promised the extension by 1 July 2010 if he was to win office in the next election, pricing it at $35 million.
The report was never released, but the PTUA and other groups criticised its public findings, contending that steeper gradients are present across the existing network, such as Burke Road in Camberwell and along the Burwood Highway.
In the lead up to the 2014 state election, the Greens proposed extending route 75 from its current terminus outside Vermont South Shopping Centre for a length of 6.8 km down Burwood Highway passing Westfield Knox City Shopping Centre and ending near a Knox City Council precinct.
[35] The Eastern Transport Coalition, an advocacy group representing seven local councils in Melbourne's East, has called for this extension.
[37] The party promised a study to investigate higher-capacity public transport to Upper Ferntree Gully, and along Mountain Highway to Bayswater.
[citation needed] The City of Whittlesea's 2016 Future Transport Plan called for an extension to the route 86 tram as a 'very high' priority.
[38] The council proposed an extension of the route from its current terminus at University Hill near Bundoora's RMIT Campus to the Plenty Valley Town Centre in South Morang.
