Tonsley Upgrade Thread

 
  justapassenger Minister for Railways

As much as I see the football service as being strategically important for public transport (running a high quality service with plentiful capacity for football and other major events is the best advertising the public transport system can ever get) I do think it would be better to have a partial shutdown on a weekend where many buses are available than on a weekday with the regular peak load.

There is at least the advantage of it being school holidays either side of the Easter weekend - having one or two days of partial closure should be bearable with the lower peak loads.

Who knows, the works may be able to be staged appropriately to have the crossover installed from Thursday evening over the Friday and Saturday, the mainline open on the Sunday (match day) and then the signalling work done on the Sunday night and tested on the Monday public holiday.

More activity around the junction today.  Trenching and duct work was happening around the Charles St ped xing and a surveyor was also active.

You never know, there could be an engineer or two there who have retained some professional pride instead of falling into public service mediocrity.

If memory serves me well, the trackwork for the junction is being made in Castlemaine and the concrete sleepers for it in Rockhampton. Danny G., the trackwork boss, said that he would be back in April to complete the junction but anything could have happened since then.

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.

Noticed this morning that this signal is now gone (not even replaced).
Lots of cabling activity occurring between the Tonsley track and Ascot Park station today as well.

In order to complete works on the Seaford, Tonsley and Belair lines, a seven day closure of the Seaford line and a three day partial closure of the Belair line is required. The work will enable:


  • Connection of the new duplicated Tonsley line track to the Seaford line (including final electrification configuration and signalling system upgrades to accommodate the new track duplication), which will allow the Tonsley line to reopen for passenger services on Monday 5 May 2014.

  • Earthworks to improve surface drainage at the O-Sullivan Beach railway cutting.

  • Electrification of part of the Belair line, between Adelaide Railway Station and Goodwood Station, to allow for critical operational flexibility on the Seaford, Tonsley and Belair lines.

  • Installation of new Automatic Train Protection equipment.

  • Other minor works, including in the Adelaide Yard.

The above now appears under Latest News on http://www.infrastructure.sa.gov.au/RR/rail_revitalisation/works_notifications. I have highlighted significant items including the reopening date for the Tonsley line.

Alex, thanks for posting those interesting photos - presumably they'll lift those points in by crane.

The DPTI notice of work refers to use of a PEM/LEM turnout installation system.  The PEM is a radio-controlled self-propelled gantry system and the LEM is an associated system of self-propelled trolleys.  (A websearch for pem lem turnout installation system yielded this information). Conventional cranes would be awkward to use because of the presence of the overhead installation.  The pre-assembled trackwork will be shifted from the assembly site at Tonsley Stn along the branch to the junction for installation.  I am looking forward to getting photos of the work over Easter.

Although DPTI earlier this week quoted a date of 5 May for reopening of the branch, this has now been amended to 'by middle of May' to allow for driver training.

This is a simple trolley system as used to install the dual gauge turnout to North Quay yard in North Freo. Same issue with no work space and overhead line. Turnout was assembled in North Quay yard and railed to location, run down on ramped rails and jacked off the trolleys.

Report pm 18/04/14.

Old turnouts cleared away.
Ballast compacted and roughly levelled.
Up turnout in place with balks being added.
Two block with a roll of plans, much head scratching and many others standing around waiting for outcome.

Assessment, reasonable progress for Day 1; work will probably continue into the night because portable lighting is on site.

I think I would have installed the crossing on the down line first, lining it up with the down main and up branch, and built forward from there.

Once the track is in the switch actuators, detectors and cabling needs to be installed.
There is a slab for a booster transformer and some hardware on the pole for a section switch and connection just on the down side of the junction.

I noticed today that there is an isolation section in the overheads just as they come away from the main line at Tonsley Junction. Is this a phase break or just an insulation section?

Some more shots from today (18th April 2014).

The first image shows prefabricated points destined for the Adelaide Up track north of Ascot Park station. The points were assembled in a yard near the Tonsley station and transported to Tonsley Junction. The unit is holding short of the Seaford down line while preparations are completed for its installation.
[img]http://i154.photobucket.com/albums/s264/billd_photo/Tonsley_Jn_2538_zps8bdfbe41.jpg[/img]



If you look ahead of the machine you'll see a rather frail-looking temporary track to carry the transporter.
There was a ramp with a considerable drop from normal rail height to the temporary level - see the middle bogie.
Once in position, hydraulic rams in the vertical components lift the track panel clear of the bogies, which are then driven out by remote control. The vertical rams, along with horizontal counterparts then "walk" the panel sideways into position.

The machine has lifted a prefabricated diamond crossing and once the powered bogies are in place it will be ready for transport

nm39

A phase break would normally occur at a feeder station (where multiple phases are available) or at the boundary between two feeder station areas. Since the AdMet system currently has a sole feeder station, the insulator you have observed on the branch will be for sectioning and will allow the electrical feed to be controlled through the Tonsley switching cabin. This is a HV cable awaiting connection to the Tonsley section of the overhead.

There are a number of section insulators throught the installation, at ARS, the various crossovers, the centre road at Brighton and at the Lonsdale and Seaford depots for section isolation.  As previously observed the Lonsdale feeder point is dinstict in having a pair of adjacnet insulators for each track.

An unofficial update until Alex C gives us some more great pictures...thanks Alex.

As of about 1800 this evening.
All track now in place but some thermit welding still to do.
They need to work out a better way of locating baulks and lining things up. With heavy concrete baulks in lieu of timber pushing with a crow bar just does not work; there has to be a better way and it is not swinging the backhoe bucket like sledge.

9:30pm, Wednesday the 23rd. All quiet on-site.
Both tracks were blocked by STOP signs pointing toward the city at the 6th Ave end of the works.
I was hoping to find a group of enthusiastic orange-vests with clip-boards waiting for a test train but there weren't any workers in sight.

Sounds like they've finished the junction - I'd imagine driver training will probably start in the next few days?

Sorry, but I'll have to say I'll believe it when I see it.

The new timetable appears as if it will just need just 2x 3000 for the peak Tonsley service. This should be achievable with the current fleet, remember that since the current timetable started there have been at least two EMUs brought into service, allowing DEMUs to get cascaded off the Seaford line - a couple of them can now be brought back.
