@TrueBelievers MM2 is more important than this project as it will like MM1 provide extra capacity through the core.
This is Victoria, not London or even NSW. I do not think that either will be built. PT is always used as an electioneering bargaiing chip.
I agree with mejhammers1 and others that there does not seem to have been proper planning done in relation to this Suburban Rail Loop project and that it seems more of an election stunt. It reminds me a bit of how in the dying days of the Napthine Government they suddenly came up with the 'Melbourne Rail Link' project which was to be a replacement for MM1.
I don't like the way that the route has been presented as a fait accompli with all the station locations already decided. I would much prefer that there had been a broader transport strategy announced first and that there was a more general direction to investigate an orbital rail corridor as a first step. However, having said this, I do support the longterm goal to provide an orbital rail corridor for Melbourne. I just want to see proper planning done first.
As for Infrastructure Victoria, I think this body is a complete waste of space. I think that the Government's own Transport department (i.e. TfV) should be more than capable of determining the Government's transport priorities. The 30 year Infrastructure Strategy that IV produced a couple of years ago appears like a poorly thought out grab bag of projects without any coordinated overarching strategy.
