The project is contractually locked in and under construction. The majority of the $1.5 to $2 billion for the project has already been spent, the government is totally committed to it and the opposition supports its completion. That video is based on nothing more than idle gossip.

If Labor pulls the plug, it won't look good on their track record after the Rozelle Metro debacle which resulted in $0.5 billion down the drain. At least the $3.1b light rail has something to show. Labor need to proceed with this one.

Why would T3 trains need to terminate at Sydenham? They could continue to the City Circle as they do now on the Local. The issue of capacity on the City Circle in the event of cancellation of the metro conversion is another matter worthy of a new thread. There are other options, but not appropriate to discuss on this thread.

It was a mistake for the metro to surface at Sydenham and take over the existing Bankstown Line platforms 1 & 2, which cuts off the option of a potential sextuplication from Sydenham to Erskineville, for which previous provision had been made. The metro platforms should have been constructed underground, which would leave open its options for a future extension. But it's too late now. I don't think Sydney Metro gives a stuff about how its plans impact on the existing network. They're a rogue agency, which should be brought to heal.

The Local line from Sydenham to the CBD during the peak morning period currently caters for 10tph T3 Bankstown Line services and 4tph T8 express South West services to the City Circle, with the latter alternating stops at St Peters and Erskineville. At the Central flying junctions, the T3 services split 6tph via Town Hall and 4tph via Museum. The 4tph T3 services and 4tph peak T8 services via Museum merge with the 10tph T8 Airport Line services via the City Circle Inner. That amounts to 18tph, which leaves 2 spare paths on the CC via Museum.

However, this will change, assuming the Bankstown Line conversion proceeds, with all T8 services running via the Airport line, which is being upgraded to 18tph with the current signalling, and the Local from Sydenham to the new Eskineville crossovers to the Illawarra Dive to Sydney Terminal only catering for SCO and SHL Intercity services, as well as South Line Regional services which are generally outside the peak. St Peters and Erskineville will be catered for with an all stations T4 service on the Main and ESR to Bondi Junction and the SCO Intercity services will be redirected via the Local to Sydney Terminal. The proposed digital signalling and ATO upgrades will increase frequencies to 24tph, which would leave spare capacity on the City Circle, along with other potential upgrades, if the Bankstown Line conversion doesn't proceed. But as I said, potential future options are worthy of another thread.

With the Bankstown line services no longer a factor, the likelihood of sextuplication from Sydenham to Erskineville ever being needed has reduced even further.

Any project can be cancelled even after contracts have been signed, e.g. the East-West road link in Melbourne, or even after work has commenced, e.g. the Malton to Dombarton line. But once work is advanced as it is with this one, no chance. The project will be completed irrespective of whether there is a change of government, any talk to the contrary is just garbage.

My comment was in the context of a hypothetical scenario if the Bankstown Line conversion was cancelled and T3 continued to run to the City Circle, but until such time that ever happens, it's not worth discussing further.

For a news clip recording the new track connection south of Chatswood (well, almost new - it was made on a recent trackwork weekend) see https://www.youtube.com/watch?v=GIqVyRwWP7c

An interesting insight into the tunneling and power supply for the City and South-west section.

“ Sydney Metro, the state agency responsible for the new line, has secretly slated April 21 for the start of “on-track dynamic train testing” between Chatswood in Sydney’s north and Sydenham in the south”

Source: https://www.smh.com.au/national/nsw/rev ... 5cur9.html

Where can metro trains cross over between tracks between Chatswood and Sydenham? I was thinking of the testing process the other day, because clearly they couldn’t cross over just south of Chatswood because that is in operation for the existing metro?

Outside of peak hours, the metro runs every 10 minutes, so the crossover south of Chatswood could be used in between services. Also, there are two crossovers north of Chatswood which allow operation from either platform (with partial loss of cross platform convenience).

I believe there are crossovers north of Barangaroo and south of Central?

Is it strictly necessary to have a crossover regularly accessible during testing? Wouldn't they mostly be manually driving and could operate in both directions on each track?

It depends how many trains they want to test and I presume they'd also want to test that the system keeps consecutive trains safely apart.

They will start with slow manual/attended operation, and progressively work up to multiple driverless trains and full line speeds. Interaction with crossovers would be part of the testing.

Escalators at the Town Hall end of the concourse beneath platforms 16 - 23 at Central have opened along with a second set of elevators.

Minor point, but Monday's changes are for platforms 16-21 specifically. The elevator and southern escalators for platform 22/23 were already open for last few months. I think those were rushed in a bit earlier, as platform 22/23 only has one escalator at the northern side (set to down at all times), thus there needed to be a way to go up or there would have been no outbound access to 22/23 from the central concourse.

In addition, I noticed that crews have started concreting over of some of the Southern concourse steps (the second set from the Redfern end), as these are effectively replaced by the new Central Walk concourse. The furthest south steps still remain, still connecting to the Southern Concourse/Devonshire St entrance, as before. The southern tunnels from platforms 4-11 are open, now accessed via the new concourse. It seems access from this tunnel to platform 12/13 may not be reinstated, what I am not clear on is whether there will be a new access path to these two platforms from Central Walk, or whether it will only be from the northern end in the final configuration. (Access to platform 14, once reinstated, is clearly shown from the Metro concourse renderings, and of course 15 is permanently gone.)

Pretty sure that there are new escalators to 12/13 and 14 either side of the Metro concourse.

Thanks, the ones to 12/13 weren't visible from the vantage point I had.

The early concept diagrams show the original access to 12/13 from the old tunnel, but this is gone now, so it seems this part of the design must have changed later on.

And Paul's latest video.. shows the access to 12/13 around 7.15.

People on social media are starting to complain about the fact that the metro fleet has longitude seating which limits seating capacity to 378. Guessing that people are use to the 3+2 seating layout that has been a the default train seating layout in Sydney since the red rattlers
