Noarlunga Line Shutdown

 
  Milkomeda Chief Train Controller

It's a pity this whole electrification project is running so late.  According the to the Department of Transport and Infrastructure website, the track upgrade was finished by the end of July, so it is only the signalling and electrification crews still working on the track.  The Noarlunga-Oaklands section should have been finished within the first few months of the shutdown. The team would have had 24/7 access to this section of track, and partial access to the track from Oaklands to Adelaide while other teams were upgrading the track.

The best example of how to how to do a project is the Middleborough Road grade separation in Melbourne.  The line was closed 1 January 2007 and reopened 28 January, with 2 new bridges, a rebuilt station, 1.5 km of new track that was up to 6m lower than the original, and with electrification and signalling re-installed.  To achieve this required over a year of detailed planning, plus preparatory night works such as pile driving.  The engineers were from VicRoads, and probably had more experience with large projects than those from the public transport entity.

What is the difference in South Australia ? Is there such a short time between when the government agrees to fund a project and when physical works are to commence ?   There is then not the opportunity for detailed planning and preparatory works.  

The next large project is grade separation of the Outer Harbour line at South Road and Bowden.  If there is less pressure to start works early, hopefully there is more time for detailed planning so the shutdown period is shorter.

Track works were only completed like a week or two ago for the Noarlunga Line not by the end of July like DPTI were claiming. Drainage and vegetation crews also needed access to the rail corridor so that would've slowed the electrification crew down further.

But yes it could've gone faster with better planning and more people employed to carry out this entire project.

They could have at least put up a photo of a similar type from either WA or Queensland though as it might be closer to what they are getting as both these systems use the Higher voltage 25K.

Holdings are now being installed onto the portal structures at Adelaide Rail yard and I saw arms off to the side of the yard that are sitting there waiting to be installed onto the holdings in the yard.

Also the rest of the electrical infrastructure is to be installed through Oaklands on Monday and Tuesday


and lastly some better quality pictures of Brighton station I took today

Majority of the wiring at the station appears to be complete I think there are only a few wires missing.

Here are two of our own gantries - taken late in the day on the 31st of August 2013.
The Wayville showgrounds are on the right, camera (phone) is facing north.

Brilliant, thanks for that picture BillD.  Looks like the weather has been as fantastic in Adelaide as it has been here!

Are those gantries only for signals or I wonder if they are also for the catenary I wonder?  Looks like they could be for both.  Also, thanks to Milkomeda for those pictures around Brighton, looks like it's almost ready for use - no doubt there's probably still bonding etc to do yet.

I was speaking to a Laing O'Rourke employee on Saturday morning and they told me that all the electrical cabling should be finished in its entirety by late October, early November.
I was also informed that there will be another shutdown of the Adelaide rail station/yard in January next year for all the fittings to be installed and electrical cabling done for the run out to the Dry Creek railcar depot.
The Laing O'Rourke employee said that they haven't got the job for the cabling to Dry Creek as yet either. Tenders have been put in for the job but no contractor has been decided upon at this stage.
  Milkomeda Chief Train Controller

I did have a feeling another shutdown of the yard would need to occur for electrification works but what does surprise me is they expect the Noarlunga line to be fully wired by late October or early November

I very much doubt at a glance in a photo that anyone would really notice the difference. The cabling will look very similar here to what it does in that photo, clearance increased and possibly a slightly thinner conductor, but otherwise very much a much of a muchness.

For the first time today since last year I've seen the boom gates at Morphett/Diagonal Road level crossing go down I thought it was a test train coming through already and got ready to take a picture but it was just a construction related vehicle coming through.

Also I saw workers putting cantilever arms up on masts near Hallet Cove today

Noticed groups of bolts underside the Morphett St bridge for the first four or so tracks. Looks very much like something to hold wires up, I could be wrong.

Emerson Bridge has a few fittings on its underside as well. What is interesting is the earth strips running diagonally across in line with the rails.

Anyone know the signalling progress on the line and the like hood of a line opening date to be set next week?

DPTI works notice 2013-08-27 for Marion Underpass includes the following:

Removal of approximately 70m of both rail tracks will occur on Saturday 31st August.
These tracks will be stacked in the rail corridor, clear of the underpass site.
From Monday 2nd September, earth works will commence. Excavation of the underpass
area up to 4m deep will take place. Earth moving plant and trucks will be on site, with
regular truck movements to and from the site taking place. Truck loads of removed
soil will be covered when leaving site.  Once excavation works have been completed,
installation of pre-cast concrete sections of the underpass and ramps will be delivered
to site on large vehicles and placed in position by crane. Back filling of the area will occur
after this, with delivery of materials and earth moving equipment again on site to complete
these activities to enable reinstatement of rail tracks by late September.
Final works during October and November will include completion and fit out of the
underpass, including lighting, CCTV, emergency phones, TV monitors, convex mirrors and
fencing.

So I guess there won't be any trains this month.

There was a large work crew setting up this morning on the west side of Ascot Park Station. I doubt that it is connected to the Tonsley Line crew. There was a reel of cable on a deployment frame so I am guessing that part of their work is to install signal cabling or something to do with the power supply. Anyone in the know?

So does this mean that the ENTIRE Seaford line will be open next year instead of this month?
What a joke!Evil or Very Mad

No the line can still be opened while the basic underpass works are in progress thats why they will be having a temporary pedestrian crossing while the works are carried out. However they need to remove the track around Marion station to start the works (Excavate the area) before putting it back (If you read the article you would know this).


DPTI wouldnt be that stupid to extend the line closure for at least another 3 months the Noarlugna Line commuters are already pissed off enough as it is.

A late September line reopening is still quite possible but early October seems to be looking more likely now.

Milkomeda: Thanks for that pic at Oaklands, it looks like the gantries are only for signals and not for catenary because there's concrete poles immediately next to it.  Interesting, thanks again.  Oaklands station looks good from that angle but I've heard from a friend who uses it that it isn't very effective at protecting you from the wind and rain.

Even allowing for optical illusions the signal gantry seems too low.

The more distant gantries are for the OH wires.

In some places concrete masts have been erected but they are right in the sighting line of signals, see 532, 1531 and 1636 as typical, and will have to be replaced by gantries. This replacement has already ben done at a couple of sites.

It does seem low doesn't it Ian; you'd wonder what sort of protection is given to stop the structure going live.  On second look it appears as though the signal gantry has been there for a while - there appears to be some rust stains on the left hand side of the support.  Perhaps it's an older one and they've yet to replace it.
  justapassenger Minister for Railways

I can confirm that is the old signal gantry which has been there since the station rebuild five years ago. You can see it clearly on the oblique aerial photos on Google Maps - and these are not recent images, as the large number of cars parked at the station for proper train services* show.

Done right, the new signals would be located further back behind the location of the camera to allow room for the platform to be extended to fit a double unit consist, at only 120 metres there will be two cars partially or fully off the platform. That is unacceptable for such a major station even if there are carriage-level SDO systems specified on the new EMUs (as opposed to Unit Deselect which locks the whole rear unit) and potentially unsafe for Adelaide-bound trains to have the rear end overhanging the level crossing behind.


I've also used Oaklands station regularly in the past, both the current one and the previous one. Neither one ever protected from the wind - the old concrete buildings simply made the wind howl as it curved around the structure, the air moves even faster when it does that. I think the current one is better with regards to rain, the depth of the platform shelter is such that you would be extremely unlucky to have rain blowing in strong enough and at exactly the right angle to hit everybody who can't retreat towards the back or stand closer to the front.

One thing is for sure, the newer more visible layout is a huge improvement in terms of security. The seats might as well have not even existed on the old one because they were always soaked in urine (from vandals, but these days you'd assume it was from seniors card free interpeak joyriders) and it's a lot more visible now it's closer to the road and doesn't have a dingy underpass as the main access route from the bulk of the parking.


* incidentally, the announcement for Goodwood station on the Belair line has been amended to 'change here for substitute buses to Noarlunga and Tonsley.'
  Milkomeda Chief Train Controller

I would think they would replace that signal gantry at Oaklands station with a taller one or have the 2 signals off on the side of the tracks infront of the electrification gantries so they are in clear view
  justapassenger Minister for Railways

This kind of thing is exactly why this work should have seen the installation of ETCS level 2 on the Seaford, Tonsley and Belair lines instead of sticking with old hat colour light signals. Signal sighting ceases to become an issue when you have a HUD in the cab which the driver can always see irrespective of what's going on outside.

I guess we just missed the boat this time around.
