Sinking of the Perth Station

 
  Bulbous Assistant Commissioner

I hope the designs for the temporary signalling between Stirling and Leederville were kept handy. They are going to need them again!

And another useful preliminary job would be to work out how to feed power to the Fremantle line when Perth yard is switched off.
"Northmetro"


the current plans are able to keep all of the lines open for pretty much the entire job, and all running at the same capacity as now..... the tunnel will be built in parts, with the Fremantle lines sent across the top of a small section of tunnel to use the old Armadale-Joondalup platforms during the rest of the works..... then once the rest of the tunnel is done, the northern three platforms (current Midland-Freo ones and the new one next to Roe Street) will be tied in via the tunnel, the trains head into there for the Midland-Freo trains, and then the temp lines are cut, and the fourth entrance line into the tunnel is tied in....... if all that makes sense....

Sinking the Freo line is easy as you describe and could be buried for the length of Perth Yard without disruption until the cut in before City West. Sinking the Mandurah line from the new tunnel to Roe St dive will cause major disruption. Including full crossover capability throughout is the most challenging bit.
Far easier and cheaper to box in the railway and landscape up to it from James St, developers will pay to build on the roof in exchange for the acreage. Lock up shops in Roe St could hide it. Assuming that the aim is to hide it, a series of landscaped bridges would restore connectivity for a fraction of tunnelling cost.

From my experience of the Perth CBD, whilst this proposal is all fine and dandy from the point of view of the business leaders and movers and shakers in Perth, to me, the incredible amount of money being spent to simply appease the aesthetic sensibilities of those that find inner city rail lines offensive  Rolling Eyes

Yes - the people whose interests a sinking will serve - business owners - should be the ones paying for it.

Agree.

In fact I beleive this whole project is only being partly completed - another half arsed construction here in "Wait Awhile". Rolling Eyes

It should be underground the whole way to Subiaco - major costs and road re-routing I know - but it will need to be done in the future due to Perths growth......

I agree with many of the points raised here (including the almost cynical but very true point that the movers and shakers of this city ought to be paying for such superficial aesthetic improvements in the city centre).

Rail extensions to Butler and Byford as well as the Kenwick link would provide a huge benefit to a city that insists on growing outwards, but with a Liberal government at the helm, I can't see this happening before I turn 70 (I am now 27 hehe).

I agree with the whole extensions; however I really do think that Mundijong should be the end of the line in the south and Yanchep as well in the North. Rather than building the whole place up and then putting in the infrastructure afterwards buck the trend and have it the other way.

As for our inner city project, I'm all for it. Perth needs to get rid of the barrier and make the connection between the CBD and Northbridge fast. The whole process of getting the project off the plans is just too slow and this is another trend we need to shake, like what burt007 said "Wait Awhile". Labour must return, even thought they suck, we need the infrastructure.

Is there, in fact, a barrier? Or does it exist only in the heads of a few architects who want a nice fat government contract?

No, its a physical barrier between the CBD and Northbridge. Its something you have to walk over or under and cannot walk straight through it. The architects I think genuinely want to do something with the space as at present its nothing but wasteland.
  GrassyNoel Junior Train Controller

Really there is no barrier, because it is possible to walk and drive over the railway. It's not the Berlin Wall. It is not easy, but then, the distance between Roe and Wellington Streets is so small that any road that crosses a sunken railway on the level of those streets will be a bottleneck for both vehicles and pedestrians. Is it suggested that pedestrian traffic hits a bottleneck on the bridges over the railway at (IIRC) Milligan St, William St, Barrack St and the city station?

Or is it a visual barrier only, the removal of which will require a fat government contract?

you make a good point grassy

while sinking the line might make for attractive "development" it isnt exactly a necessity

sometimes it's nice to actually see what happens in a city, rather than hiding everything out of sight

Most rail users in Adelaide believe that the railway station was sunk because both the railway and its users were seen as being unsightly.

...And they say Australia s a classless society...

I gather you guys don't live in Perth then! It is an unsightly wasteland, however if they put some turf down fixed the landscaping and fixed up the Wellington Street Busport then maybe it wouldn't be so bad. But as it is now its crap and something needs to be done.
  62440 Chief Commissioner

Looking at the planning proposals, the block would be generously sprinkled with towers and would remain "a barrier". If the railway is so ugly, why not just roof it over like Fed Square, ramp over Roe St down to James St and down to or over Wellington St. Any architect could make that work and the train passengers would not have to put up with huge disruptions.

If the ugliness of the railway were so important, it never would have been dieselised, let alone electrified Smile

Its not about the ugliness of the railway, its to do with making better use of inner city land. Theres nothing wrong with the railway, just the reserve, however if you want to make full use of the land then railway needs to be sunk! Surprised
  GrassyNoel Junior Train Controller

Perhaps a railway is the best use that can presently be made of land that is only there because two swamps are being covered over Smile

There is a good reason why Lake Street was so named

Is that why they won't invest in proper lighting for the station?

Hi all,
I'm confused. How can an entire station be sunk Question. What is involved with this process Question.

The title should really be renamed. The station isnt going to be sunk, just the rail lines west of Perth station.
  dw54 Assistant Commissioner

And we can add, I think fairly, that Subiaco station has been "sunk", so to answer the question: study what happened at Subi.

However, you're right. The title is wrong. The western approach tracks are proposed to be lowered.

I think little of value would be achieved, but that's my 2c.

Speaking to someone inside the PTA the other day, it will probably be about Feb or March next year before any serious work is begun. Something to do with the fact they are still finalising some of the tunnel design in term of new regulations required for tunnels.
  Northmetro Junior Train Controller

So if this all takes time, will this be the familiar story of the federal funding being fixed, the state government managing the contracts, another resources boom taking off and the state government in the s**t with their contractors' costs overrunning because they haven't spread the risk well enough?

The old timber footbridge will be dismantled and the construction of a new underpass between platform 5 & 6 will commence. Shocked Demolition of Old Western Concourse (south)

Armadale services will from refurb'd platform 6. Platform 11 reinstated for 6 car sets (for special events). Commence underpass to link with Perth Underground. Demolition of old Western Concourse (north).

Stage 3: Slew the turnback to form Midland down. Midland line will use platform 7 (east). Platform 9 becomes non-operational. The 827 crossover will be removed. Construction of northern section of underpass to platform 9, 10 and Roe Street.

Stage 4: Reinstate turnback. Commission 818,819 (east) crossovers and 828 (east) points. Platforms 9 & 10 commissioned. Midland line services off platform 9 & 10. Complete underpass link to Perth Underground.
