Noarlunga Line Shutdown

So is the substation actually finished and live yet.
Aside from all the ADMET hype, I would doubt they would power up while much of the wiring it still being put up.
Of course this leaves the issue that the Seaford depot will have no power to even turn the lights on, on our first new train. Sad

The line would need to be in sections to turn off the power etc in emergencies, so then if they connect up or switch on the Noarlunga Centre to Seaford section they could power it up and leave the rest of it off till it is actually needed for testing etc. Most overhead electric transmission is done this way so that if something goes belly up it can be isolated and fixed safely. They can then continue on with putting up the overhead wires till the need comes to connect to the live section, a weekend shutdown should do this bit though. All they need is a completely dead section between where they are working and the live section, which in this case could be several dead sections of overhead wire, just in case of an overshoot or something. They are pretty well advanced on the wiring down there away from Noarlunga Centre station towards Adelaide.

Halo, yours might have slipped!

There was an advertising campaign for switch on 17 June although I suspect it didn't actually happen on that date; true love never does run smooth.

Do you know something?

David, right and wrong.

The system is broken into sections, hence the reason for the double poles about every 1.6 km. These sections allow both isolation and also the connection of Booster Transformers which "suck" the return current out of the rail and back into the return wire.

As it stands there is only one substation on the system, that at Lonsdale, meaning only one feed in point. another substation will go in when the line is extended to DCRCD.

At about 2 weeks ago the overhead finished at the contested poles opposite Columbia Cres Hallett Cove.

I must drive past again this afternoon.

Re the power, I've been told numerous Cummins Gensets have been either temporarily (most likely) or permanently located along the line for testing and perhaps permanent back up. Can anyone confirm or deny?

Intrieging idea if its permanent and indeed viable one for if there is a temporary power failure (or other failure) at one of the sub-stations, if only to supply enough power to maintain air-con etc on stranded trains or perhaps to get a train at low speed to the next station to unload passengers???

Ok you electrical boffins, is that concept even feasible?

for info, the 1.6km double posts are for overlaps, where one wire ends and the next begins and there is an overlap span between the double masts. Most of these are fitted with current jumpers and so are connected through. At feeder points and elsewhere, the overlap wires are kept electrically separate and may be connected through a switching device. The locations for insulated overlaps are shown on the sectioning diagram.

OK, easier question then, is the substation complete yet?

Gateway to heaven!

As of this morning, masts, portals and gantries are at an advanced state at Brighton with some cantilevers fitted; no wires strung.

It would be possible to excite the system from generators but finding a 415V to 25 kV transformer would but difficult.

Standard generators do not like supplying single phase loads, such loads cause the rotor to overheat; a specially designed alternator is required. There is also a problem when there is no load because the line is capacitive and alternators arc up at supplying capacitive loads.

It can be done but specially designed equipment is required.

There would be some merit AM investing in such a unit which could be mounted on a trailer or set of trailers one for the generator/s one for the transformer and switchgear. I am involved with the supply of equipment like this to SAPN at present.

A few portals up at Keswick, bit of zoom really highlights Anzac Highway being over a dip

Well, even if nothing else was to be accomplished those tracks look a lot straighter than the ones they replaced.

The southern end crossover, note the plethora of TSR signs and you can just see the arrow on the ARTC signal

I noted that the indicator showed to change at Goodwood for trains to Tonsley and Noarlunga! Could be confusing for non-regular travellers

Closure of Tonsley train line to be extended to November to allow 15minute service.

THE Tonsley rail line will be partially duplicated to allow 15-minute train services to run once it is reopened. Infrastructure Minister Tom Koutsantonis said the Government had asked Parliament's Public Works Committee to approve the initial stages of the $63 million Tonsley Park Public Transport project, joint funded by the State and Federal governments. He said this meant the Tonsley line would remain closed until November 2013, about eight weeks longer than anticipated. "Beginning the additional track, electrification and signalling work as soon as possible provides us with the opportunity to complete the works within the existing closure," Mr Koutsantonis said. "We again are asking for commuters using the substitute bus service to wait a little longer in return for a much better service."

The important bit is the extra 8 week shutdown for the Tonsley line. It's been shut for about 12 months now, whats another 2 months.

As of 27th of this month it will have been closed for 16 months, if it stays closed till November, that means for 18 months no trains have run. So much for a year long closure.

But the line was deliberately built off-centre so it could easily be duplicated in the future.

62440:  Thanks for these pictures, I'm assuming they were taken from the front of a Belair-bound train?

So they went for a portal structure over the four lines; correct me if I'm wrong but it's actually only for the benefit of the Seaford tracks on the far left whereas the Belair and ARTC tracks won't need catenary at this point?  At least they appear to have put some redundancy into the system, Belair could well go electric at some stage in the future.

Malcolm Fraser made an offer to the states in the late 1970's to commence 25kv interstate electrification (in the days before ARTC) but no state government at that point was interested; it's not out of the question that interstate links might be electric in the distant future.

All 4 tracks from Adelaide to Wayville are available to either Seaford or Belair trains as they always have been.    

I assume the eastern tracks will tend to be used for Seaford trains, and the western pair for Belair trains but there will be some trains that use the other pair.

So the line on the right of the photo is not an ARTC track?

Not between Mile End and Wayville - the ARTC track runs to the west of the Keswick Passenger terminal here.

62440's photos of the new Wayville station a couple of posts ago show the end of the 4 track section and the ARTC track coming in on the right.

My theory is that the crossover just south of Wayville will be where electrification ends on the Belair lines, as it is the last crossover the Seaford bound trains can use heading south before the underpass

SA Track and Signal diagrams shows the "Belair" line overhead finishes at the southern end of the Goodwood station platform 3.
Whilst it seems strange to install the overhead that far, it does mean that platform 3 at Goodwood can be used as a turnback (possibly so that the EMU's can run the Showground special)

Matthew.

For what it is worth the G Vincent track diagrams see http://www.sa-trackandsignal.net/Pdf%20files/Adelaide/AD004.pdf show the electrification on the Belair line ending just past the down end of Platform 3 at Goodwood. This is part of the proposed turn-back arrangements for serving the showgrounds.

How much of an authority G Vincent is I do not know but others seem to cite him as reliable. I am not sure all the signals shown at the down end of Wayville will be (need be) installed.

Electrification progress report.

I drove along the line from Brighton to Hallett Cove Beach and I am concerned at progress with the electrification.

Contract management experience has shown me that when work does not proceed in a linear manner but is scattered and piecemeal cost and time overruns result.

No wires are installed north of Hallett Cove.

Poles and gantries are missing in parts between HCB and Marino; no cantilevers are installed.

Poles and gantries are erected Marino to Brighton (appears complete) with many cantilevers installed.

HCB and HC station awnings do not have any hardware installed.

Thee are significant quantities of conduit both electrical (orange) and signals (white) being installed so there must be a lot of cables still to pull, terminations to be made and equipment to be commissioned.

Unfortunately my concerns about signalling for the Belair line at the Goodwood underpass proved well founded; let's hope "they" can do better this time.

Ian: Not that I'm making excuses on their behalf but they could be waiting for:
  • Removal of overhead obstructions such as trees, other power lines, street lights, etc.
  • Relocation of underground services such as drains, cable conduits.
Supposedly September is the time for testing to begin so there's still plenty of time for them to get the wires strung all the way; I'd imagine Seaford-Noarlunga will see the first test services before they try to run a set along the entire length of the line.
  Milkomeda Chief Train Controller

DPTI are also reporting that the Noarlunga Line will not be open until mid September. I was hoping for an early September reopening oh well
