While I do actually support a segregated metro system for the inner and middle ring suburbs, they've gone about it back the front. The North West Rail Link should never have been built as a metro. It's an outer suburban line which should have had an express route through the inner suburbs similar to the Western, South and Northern Lines.
I've written about this previously. You need to think outside the Sydney square. I see the NW metro as a blend of S-bahn and U-bahn that delivers a Perth level of performance to Sydney. Like the Perth lines, it'll be faster with an all-stops journey than a typical Sydney Trains part-express, part-stopping service such as you mention. I've given all the comparitive time/distance/stops figures in earlier posts. If it was delivered as just another outer-suburban line runs by double-deckers, you are condemning users to a slower journey (and with less capacity) than they will have on this metro.
The two
overwhelming problems of Sydney/NSW Trains are journey time and capacity. The metro addresses both.
As for "thinking outside the Sydney square", how else can you view it? That doesn't mean that I'm oblivious to how rail systems are run elsewhere. In fact quite the opposite. I've travelled on many suburban and metro systems in some of the world's major cities in Britain, Europe, Asia and North America, so I think I have a good grasp on best practice for urban rail systems. Yes Tony, I've been to Prague as well.
Designing a new rail network from scratch is one thing, but where an existing legacy network exists, there needs to be a different approach. You can't just trash it and compromise its operation by picking off bits and pieces to suit a new metro agenda, which is what is happening now with the current metro proposals. There's certainly been no attempt to make any meaningful investment in upgrading the current infrastructure to compensate for its loss of parts of its network to the metro system.
A case in point is the confiscation of the Epping to Chatswood Rail Link to form part of the Metro North West Link. This was originally designed as part of the Parramatta to Chatswood Rail Link to divert Western Line passengers bound for Macquarie Park and North Shore destinations and Upper Northern Line passengers from the Inner West corridor to the CBD, taking pressure off the congested suburban tracks from Strathfield to Central. Now that has been turned on its head, as Upper Northern Line services will be redirected to the original route to the CBD via Strathfield, exacerbating the already congested part of this corridor. Instead of providing additional track amplification into and through the CBD, their response is to redirect more Western Line services into Sydney Terminal. Even Labor's original City Relief Line from Eveleigh to Wynyard/Barangaroo makes a lot more sense. The new metro will do nothing to offer any relief on this corridor and neither will the proposed Metro West, contrary to the government's assertion. I'm sure that will go down well with Western commuters and guarantee the Coalition losing whatever seats it still has in Western Sydney.
I know that you are passionate about Perth's rail system, but it's irrelevant in comparing it with the far more complex Sydney system. They're chalk and cheese. I will agree with you though that the Sydney Trains system is far too slow, when it has the potential to be speeded up if there was the political will and committment for further investment in infrastructure upgrading, in addition to expansion of the metro network.
As far as capacity is concerned, what you conveniently chose to ignore, particularly on a long distance outer suburban line like the Metro North West, is that a DD service extended into the CBD could also be potentially operated at a similar frequency to the metro (15tph) with double the seating capacity. With ATO and new station design, a DD service could operate at up to at least 24tph with an ultimate capacity of around 30,000 ph compared with the metro's 40,000 ph. But will that capacity ever be needed?
