I support this project, there are so many questions that would need to be looked at while planning this out they are as follows:
So is high capacity signalling going to be used along the whole section of SRL?
Will they use semi-automatic operation, or look into fully driverless operations?
How long are the new rolling stock will be? How many seats? How many doors?
Now where is the new stabling going to be located? Will it be underground or above ground?
Would it make more sense to start on all sections by 2022 date?
And it'll likely take 15-20 years to get the construction completed. How many boring machines would it require?
And where are the locations for the boring machines to lifted into? And what properties would need to be taken to allow the boring machines lifted done in the sections?
And how deep are these stations going to be? And how would the stations be modified to allow the new connections?
Is every station in the new SRL getting fit with screen doors?
How frequent is the service? Every 2 minutes?
Also despite supporting there are a few fair criticisms. It's an early announcement just before the election. Infrastructure Victoria was set out to take politics out of infrastructure, but didn't have this in their plans, but I have to say Infrastructure Victoria put East West Link "needs more investigation", but no mention of circle rail line. Just shows Infrastructure Victoria has the short term/medium term stuff, but nothing like really long term. Even the metro 2 proposal, they said "also needs more investigation", putting it at the same standard as east west link. Even though east west link is already known as a poor solution, they didn't negate it in their options. I don't like Infrastructure Victoria way it decides which projects work or not, it didn't support Doncaster rail and it was 50% supportive of Rowville rail, where it choses to go the more economical sound option improving existing network of buses. Although Labor kinda neglects all the smaller improvements like all the whole network of buses and road pricing. I think a mixture of long term and short term needs to happen.
Also despite Labor investing heavily into transport projects (that being heavy rail and roads mostly), there is obviously a lack of a co-ordinated transport plan. This is a problem, since the government of the day could just make random pledges of projects that might not stack up economically at the election to gain popularity. It's definitely a concern that needs addressing. Also neglecting the smaller improvements, such as buses and cycling. Buses & cycling get quite a small portion in the budget compared with rail and roads. Which is kinda sad since it's cheaper and it is widespread. You can improve a whole network of buses and cycling paths over the whole metropolitan Melbourne and wouldn't cost that much.
As usual the opposition has nothing of substance when it comes to any type of infrastructure. Guess what they criticise Labor for? Skyrail, which isn't a issue, purely Nimbism. Also criticise about cancelling East West Link, which is purely a political project that wasn't for the public interest at all. And what else, oh yeah saying Labor neglects regional rail, oh I forgot they actually were the ones that had the guts to start the regional revival rail project. Yeah why don't the opposition actually make valid criticism of the lack of co-ordinate transport planning and create their own, oh wait I forgot they did? Yeah I remember they created PTV to do that in 2010 the only thing that came out was The PTV metropolitan rail plan, which they never followed through on. Remember they changed the route for Metro rail and cancelled Doncaster/Rowville rail links.
