Tonsley Upgrade Thread

The announcement today states that the Tonsley line is not expected to reopen till February 2014, two years after closure. I'll be surprised if anyone actually returns to these trains, I sure have found driving a lot easier than commuting.

'The Tons will reopen when the level of interest in patronising the line has dropped to a sufficiently low level that we can close it' is what I think the press release should have said...

Aaron, I would have agreed with you except for the duplication works.

Personally I have found the Tonsley line very useful even though I live further south and I know others who also use it. To my mind it was an under appreciated asset.

Forgot to mention last week I think I saw them beginning to do signalling works on the line as I went past the crossing on Daws Road.

I noticed poles erected on the duplicated section to the north of Daws Rd. Also noticed crews working on the turnout just north of Celtic Ave and the signal box just south. The signal were still not illuminated.

I would hope the Tonsley line becomes a more appreciated asset when the Tonsley TAFE opens on the 6th January 2014 and as the precinct expands. Other tenants on the old Mitsubishi site will be Flinders University, Tier 5 & Siemens along with a residential development.

Thanks Milkomeda and Tonsley213, good to see those nasty Liberals haven't killed all progress on reopening the line. Was it really worth starting a huge argument with the state government over $17m, of course not, but who said anything the Liberals do made sense ?

Nothing makes sense in politics so we will not mention Oaklands station or the tram bridge at Black Forest with the opening too narrow for additional lanes on South Road.

I just hope that somehow a bus interchange with a chance at working is built at Tonsley.

I also hope that a train/tram interchange is built at Goodwood.

The signals just N and S of Celtic Ave are now lit red.  The Celtic Ave LX was activated briefly while I was having a look this afternoon.  Signal and LX cabinets at Clovelly Pk were being worked on.  Balises have appeared near a wheel detector just S of the Charles St Ped Xing which is having new mazes constructed (automatic gates?).

It sounds as though the Tonsley line upgrade is advancing ahead rapidly and finally something good is being done to improve the line!

Update.

Metal portals have been erected at the crossings at Daws road and Celtic ave also on most poles/masts between Mitchell Park Station and Tonsley Jtn, cantilevers have been installed, they may be installed further south I haven't ventured any further.

Update

Catenary and contact wire has been strung up from Tonsley through to not far north of Celtic Ave.
  62430 Assistant Commissioner

Location: Metro Adelaide
Catenary and contact wires with droppers now installed on down and up lines from Thirza/Daws on to main line at Tonsley Jn.  The overhead configuration corresponds to the yet to be installed double junction and not to the existing track layout.  In particular the existing crossover has not been wired, which precludes the running of electric trains before the new pointwork is installed.  I think that much of the overhead work must have been done last weekend. Some pictures taken on Monday 17th:

1. Branch looking towards Tonsley Jn


2. Looking S at Tonsley Jn


3. Looking N just N of existing crossover

Any word on when the junction work will be done?

I noticed this afternoon that the stop barrier on the branch at Tonsley Jn has been shifted clear of the track. Is this an indication that some test train movements are underway or imminent?

I had a closer look at the branch at Ascot Park late this afternoon.  The stop barrier at the junction was lying clear of the track.  The stop signs on the down track at Signal 1036 have now been removed and only one sign remains on the up track at this location.  Now that the boards have been moved, the balises and AWS approaching Signal 1036 in the up direction can be clearly seen on the down track in the photo below.  Also a 90 speed restriction sign is visible.

That signal is a wee bit close to the up track.   I assume it will be shifted when the junction is completed.

Just my thoughts exactly.  Looking closely at the photo, there is a concrete base and orange cable ducting that could be the new signal location.  

If some TSRs were visible, we would know the line is due to open!

That signal could be temporary till the new junction is installed. So as to allow single track operation and completion of track work at the junction it will be removed and placed the side of the track that it is now close too.

At the Clovelly Park Park-and-Ride on 5 March finishing touches were being made to lighting at the 600-space car park. It is a surprisingly long walk from the car park on the south side of Alawoona Avenu to the station. Pedestrians are required to cross Alawoona Avenuel, and there is no designated walking route. It is a pity the car park were not on the northern side of Alawoona Avenue, which would have reduced pedestrian-vehicle conflicts, and required a shorter walk.

At the station itself there has been minimal upgrading during the shutdown. It has even accumulated some graffiti.

I would suggest this is because the station was (still is ?) planned to be rebuilt south of Alawoona Avenue.

The DPTI Tonsley Upgrade webpage seems to have been recently updated with reference to recent electrification and signalling work. The implication is that the service won't now resume until after the new junction is installed. When I passed last week, the signal cabinets at the junction were open and being worked on.

Significant work has been completed on the Tonsley line to date, including electrification, resleepering and duplication of 1.1 km of track to enable a future 15 minute service when operational assets allow. The re-signalling of the Tonsley line to ensure compatibility with the overhead electrification infrastructure was completed in late 2013. Final works involve matching in the new double track junction with the main Seaford line. This work is extremely complex and has involved detailed planning by the track, electrification and signalling teams.

Signalling works are underway to incorporate the new dual track section of the Tonsley line and to signalise the new dual track junction configuration, to be commissioned in co-ordination with the final junction works. Electrification works such as the installation of masts and overhead wiring for the new duplicated junction and track alignment are complete, with final adjustments and quality checks required when the transition is made to the new track. On completion of this work the Tonsley line can re-open to passenger services.

So with the State Election safely out of the way (at least the ticks in boxes part), we can soon expect announcement of the shutdown of the Seaford line for a number of days while the extremely complicated task of installing the double-line junction, signalling mods & overhead adjustment is completed. Welcome back to the N3 and N4s!

Did someone already mention this work is scheduled to happen over Easter long weekend?
If this is true, what about the Crows match at Adelaide Oval on 20th April? Footie tickets valid for free travel on the N4?

I suspect the substitute buses will probably be renamed to S1 and S2 now

I'd expect that trains would continue to run between Brighton and Seaford over that period, as per the testing period with the electrics, as the overhead could be isolated, east of Hove. This means the old N1 (Adelaide - Wayville - Brighton Express) and N2 (Adelaide - Brighton All Stops) services would cover the gaps, rather than an N3 and N4. With a fully operational depot, railcars, and staff available, only a fool would close the entire line now.(unless other works that we don't know about are applicable).
