Sunshine has a lot of merit, besides being the most common sense choice.
NEIC, massive investment over the coming decade in services and industry.
Greenfields area, no matter how you cut it there is going to be some interesting track configuration at Sunshine. Looking at two additional platform pairs possibly underground.
-MARL will need it own platforms
-Platforms 3 & 4 will service the WRP
-Additional Platforms for regional services?
It’s going to be complicated try to shoehorn this into Footscray, not to mention the price.
Even distribution of passengers across the network. A problem that stations like Flinders Street and South Yarra currently have. Post MM1 Footscray will become a major interchange for MM1 services in addition to the ever increasing demand thanks to the many apartments popping up.
Sunshine becomes your major regional interchange away from the inner core.
