Is it just me or have politics and greed combined to knobble the provision of fast convenient rail access to YMML?
The politics: the route is a huge dogleg from the airport through Sunshine station - the (labor voting) crime capital of Victoria, then by regional lines to the central city.
The greed: Folks, this is going to be a slow, infrequent service bedeviled by crime and unnecessary suburban rail stops. This is nothing like the frequent express services of Europe. And the cost! $10billion! And the time - 9 years to build starting in 2022!
Thus there is not going to be any cheap, viable, convenient alternative to the greedy airport and it’s carparks for at least another 13 years!
