Great news, i dont use it but it must be great for those commuters who do.

The article stated "Transport Minister Stephan Knoll said the additional cost would be spent on purchasing 15 new electric rail cars." The "additional cost" was $175 million to be paid by the state government.SBD wrote: ↑Sun Jul 15, 2018 3:00 pmWhat rolling stock will be used? There is nothing in the press release about either buying more 4000-class, or about converting the 3000-class to be powered from the overhead wires. I don't recall anything in that area for stage 1 either, as the stated benefit was in getting Seaford train sets to Dry Creek under their own power.
1) According to the Public Works Committee Report No 613 (january 2018) (https://www.parliament.sa.gov.au/Commit ... =5&CId=340) the scope of the project is to Gawler Central.SBD wrote: ↑Sun Jul 15, 2018 3:00 pmI have two questions:
1) Does Stage 2 "Salisbury to Gawler" only go to Gawler Station/Gawler Junction, leaving the necessity for at least a stage three to Gawler Central or beyond, and possibly a stage 4 to Roseworthy, or is it shorthand for electrification of all current services?

The Public Works Committee Report 583 tabled November 2017 contains a schedule of works for the Operation Control Centre (OCC) Relocation project:Listy wrote: ↑Wed Jul 11, 2018 10:59 amIt could be SAHMRI related. The trenches do look like footings, but so far they've been laying pipe in them and then covering them over again. The trench running along the boundary fence which connects to this construction goes at least as far as the new rail underpass & 3 more trenches with pipes were recently built heading away from the work site & toward the train lines.Llessur2002 wrote: ↑Tue Jul 10, 2018 5:18 pmStrip footings are currently being dug in the Adelaide railway yard on the opposite side of the tracks to the existing control centre.
Is there a new facility being put in here when the old one is closed to make way for the new SAHMRI 2 building? I thought it was going further afield to Dry Creek or something...
Thus the observed work would appear to be the building to house the new power supply and safety critical signalling equipment.The required works for the relocation and vacation of this site include the following:
- The relocation of the Adelaide Rail Yard power supply, involving the construction of a new power supply building within the Adelaide Yard to house the railway power supply and safety critical signalling equipment. The power supply will require a new high voltage external power supply from SA Power Networks.
- The fitout of the new OCC at Dry Creek, including a new control room and associated services, and the connection of the control room to the ground floor equipment rooms.
- The construction of a duplicate operationally critical main and backup computer-based railway systems and networks.
- The completion of redundant high capacity optical fibre links to connect the new OCC and signalling equipment to the Adelaide Yard to replace the existing local connections. This will comprise an interim solution to enable early testing and provide redundancy until the Gawler Rail Electrification Project conduits and aerial fibre cables are completed.
- The facility commissioning, including staged commissioning of new systems, and staff and equipment relocation.
Just out of curiosity, wasn't the Adelaide rail yard completely reconfigured during the months long closure a few years back to allow for the Seaford electrification? Wasn't the electrification of OH and Gawler still on the cards at that time, and the whole yard designed for electrification of the 3 lines?. Wasn't SAMRI and associated uni buildings already planned even then? Why wasn't the new power and signalling done then? Not saying its a major drama now, but surely it would have been cheaper/quicker/easier to do it all at once?PD2/20 wrote: ↑Tue Jul 17, 2018 6:10 pmThe Public Works Committee Report 583 tabled November 2017 contains a schedule of works for the Operation Control Centre (OCC) Relocation project:Listy wrote: ↑Wed Jul 11, 2018 10:59 amIt could be SAHMRI related.

I had a look at the site yesterday from the river side and noticed that the 4 huts in the work compound bear Lendlease logos. Does this indicate that Lendlease are undertaking the OCC relocation or does it reflect their role as main contractor for the electrification (include resignalling) work?
The Yard itself is ready to go for Gawler Electrification. All lines have overhead wires and the Gawler line has a few gantries in place ready for wireclaybro wrote: ↑Wed Jul 18, 2018 10:12 amJust out of curiosity, wasn't the Adelaide rail yard completely reconfigured during the months long closure a few years back to allow for the Seaford electrification?

The January 2013 month-long closure saw the erection of the overhead gantries over the immediate approaches to all 9 platforms from east of Nairne Junction (where the Seaford/Belair and Port/Gawler lines diverge. The pointwork of the crossovers at Nairne Jn between the Belair/Port?Gawler lines was replaced on a like for like basis. Apart from the removal of a couple of crossovers under the Morphett St bridge on the approach to Platform 2, the track layout and signalling of the Adelaide Yard remained unchanged during the revitalisation and Seaford electrification. I believe the signalling installation dates back to the late 1980s. The Seaford line signalling and associated communications links beyond Port Rd were completely renewed at electrification. As part of the Torrens Jn and T2t works the signalling out to Croydon and North Adelaide have been replaced.claybro wrote: ↑Wed Jul 18, 2018 10:12 amJust out of curiosity, wasn't the Adelaide rail yard completely reconfigured during the months long closure a few years back to allow for the Seaford electrification?

In Adelaide Yard only the Seaford and Belair lines into Platforms 1-4 currently have overhead .
Could they move Dudley Park to either side of Pym St i.e southbound south and northbound north of intersection and scrap Islington? Make Ovingham high frequency instead.claybro wrote: ↑Fri May 18, 2018 11:34 amAgree that stations that do not directly service a high traffic retail or services areas, or are not suitable for accommodating a bus interchange so that local buses can feed into them should be closed. These small little suburban whistle stops, might be convenient to the couple of hundred people in the immediate few blocks, but as you say, they add huge cost and time constraints on the system as a whole. Not particularly familiar with the Gawler Line, but if these stations are in low density areas, they should be closed.
From a practical point of view, both Dudley Park and Ovingham should be scrapped. The plot twist? They equally shouldn't be, as both stations help facilitate efforts to densify the area, especially along Churchill Road. There are no immediate bus connections, but again Churchill Road is literally a stone's throw away.claybro wrote:There's no way Islington would be scrapped, it services an expanding retail and soon to commence high density housing precinct. If anything Dudley Park could be scrapped, it is in a low density suburb, has no provision for bus connections, is not highly visible from any main road and serves no shpping or service precinct. So it is typical of many Adelaide suburban stations and demonstrates many of the problems with the current train system.
One thing I've been curious about for a while. Do you know why it's called "Nairne Junction" even though it's not in Nairne?
Islington station should have a good bus connection on Regency Rd. Unfortunately the only route that serves it is route 300, which is low frequency. If we eventually get a grid for our public transport network, Islington Station-Regency Rd will be a good connection point.Nowlistencarefully wrote: ↑Wed Jul 18, 2018 9:59 pmCould they move Dudley Park to either side of Pym St i.e southbound south and northbound north of intersection and scrap Islington?
