Sydney Central to Parramatta

The only problem with your western express is the following.

1. Every train on the western line is already a western express from Parramatta. Parramatta is not lacking for service whatsoever. People from Parramatta have no right to complain about rail services.
2. Bankstown services normally use the inner circle meaning that they go in via museum and not Town Hall. The city via Bankstown services from Liverpool are normally the only services that use the outer circle.
3. Moving western express services onto the city circle is just going to screw over main south services again. For the small pain of a couple of minutes between Redfern and Central they should get over it and accept that they still get a 25 minute service from Parramatta and the same time by train from Penrith as it takes for a service from Liverpool.
4. The western line doesn't need fixing. It just needs separating from main south services between Strathfield and Granville. This will free up 10 trains per hour for both lines.

1. Tend to agree. My concept was to provide more capacity for Parammatta and beyond
2. thanks for the info
3. Why? Issue is that extra trains from the west (assuming needed) need to go somewhere and the traditional NSL cannot take much more nor can the terminal stations.

4. Yes, agree you can delete all the references on my original post except

- Retain the Metro to Ashfield to remove 4 trains per hour and the bottle neck it blocks on a further 8 trains per hour

- Beyond the Straithfield, the loss of the CC and Epping services enables both the Nth and Middle tracks to be merged with express

- The SW services now remain on the southern tracks, currently 8 trains per hour, increase to 12 trains per hour. 6 each via Granville and Reagents Park.

- 4 slots to be used by trains running all stops from Westmead or Paramatta to Ashfield.

- SW trains have slight express west of Ashfield depending on demand at intermediate stations.

- Track capacity of south tracks is now 16 trains per hour.

If you move western line trains onto the city circle then you are again screwing over inner west and main south services as they will hold up those services at redfern while a western line train takes a spot at the flyover. The north shore can easily handle 24tph.

The problem is past Strathfield where western, BM and main south line services merge with one another and the track goes from 6 to 4 and the ensuing conflicting moves occur. An extra track pair is needed to fix this issue. Meaning something has to go underground.

If the all stops inner west services terminated at Ashfield instead of Homebush then many of the issues with capacity on the inner west line would go away. The distance is so short and the service would not get in the road of the semi express services.

Turning the metro at Central for Parramatta in my opinion would be even cheaper as it is only about 10km further to drive but you have not got a dozen or more stations to fix up and it is easy to hang wiring on the top of a tunnel.


That is apart from all the chaos involved.

Metro from Redfern to Paramatta is just under 25km and would cost in the order of $6 - 10B as tunnels are by far the most expensive bit.

I proposed to Ashfield which is about 7km and would require 7 x UG stations including Ashfield, each worth about $150m a piece so about $1-1.2B for the stations and 7km of tunnel another few billion.

Meanwhile on the surface things are streamlined and tracks are less dual purpose.

What chaos?Shane if the 15km of NWRL cost $1.15b I doubt that 25km would cost anymore than fixing up the Bankstown line plus the central to Sydenham tunnels plus the chaos involved in doing it.

I do agree that a surface line would have less headwind problem but tunnels would be far easier to implement.

Evidently there are about 20,000 people on the DD who could get on the metro and get a one seat ride to the CBD but I don't know how many would get on the metro at Bankstown.

Eventually it all depends on money

The NWRL is costing $8 billion dollars.

The NWRL project cost $8B

You say the tunnels only cost $1.15B, so where is the rest???

Ok the NWRL includes
- trains (which you also have to buy)
- full service depo (which you also need to build)
- trackage above ground, 5km or so
- modifying the existing ECRL
- 6 stations (which you need to build at least 3).

So while it is well known that going underground is very expensive, we have 15km of tunnels that somehow cost less than 15% of the budget. This I find very hard to believe.

Again lets compare with other like projects in Brisbane, WA, Vic and even the ECRL itself, none are anywhere near $1.15B for 15km of tunnels. Most are similar in per km of tunnel as is NWRL.

I know what the press release said, but what is the scope of this $1.15B ? A hole in the ground with tunnel liner?

Ok on the rest CC but the western line

Recheck the number

East of Straithfield
- 4 trains per hour inner west
- 8 to SW

- 4 to Epping
- 16 Western main (12 express and 4 become local)

- 6 to CC
- 4 (I'm guessing) to Blue Mountains

Total 42? (please correct mistakes)
