The design itself might, but it will be politically impossible for the next 30-50 years to do anything else to the Caulfield-Dandenong corridor, so nothing will be built. Any changes to the parkland they're creating down there, and the government would be toast, so they wont touch it at all. Infrastructure Victoria has backpedaled away from wanting four tracks, which I assume is a Political direction, because even with High Capacity Signalling the mix of Metro, Vline and Freight Services is never going to allow the frequency and speed they need.The Skyrail design permits quadruplicated track between Oakleigh and Dandenong.G'day all.
What about full duplication of the Crimebourne line with an extension to Clyde? Also the long awaited (almost) forgotten third line from Caulfield to Dandenong.
3rd track Caulfield-Dandenong has had the kibosh put on it, courtesy of the idiotic decision to build 'Skyrail' (CTD) as duplicated track instead of provisioning quadruplicated track.
Though Clayton an additional double track viaduct would be built over where the railway alignment Is now (South of the viaduct currently under construction) , same thing at Noble Park, though at Chandler Road the viaduct swaps sides (the second viaduct can ease out this slew their making)
Caulfield to Oakleigh well that's In the too sticky basket at the moment.
What to do at the Frankston line Junction
Looking at the area map for Caulfield-Hughesdale, it looks like the only options will be property acquisition, or building the new viaducts down the centre of the other two, ruining the parkland.
I really think this has been largely a mismanged project and should have been better coordinated with and a part of the Metro Tunnel project to give the best outcomes across the board for the Metro line and Gippsland V/Line, who have largely been ignored in all this.
