SWRL Construction Progress

Anyone in a position to confirm there's a crossover at the top of the southern flyover please?

I recall seeing an aerial shot of trackwork being laid on the curve where the tracks head out onto the embankment, and there was a gap in each track as if a pre-assembled crossover was to be 'dropped-in', but can find neither the original picture or a new photo of that area with the trackwork completed.

TIA

EDIT - Google(Sat)Maps is about 3 years out of date - still shows only 3 platforms.

Weekend progress (Feb 22/23,'14) will likely not be readily visible from the train:
- the 'Down/Up Trailing CO' (northern end of Glenfield station) OHW finished by Monday 24th, to complete OHW except at the northern flyover exit,
- the track grinder was noted at work making passes across the top of the northern flyover,
- 1500v feeder cables for the southern flyover ramps were installed on a portal mast south of the station (but may not be finally connected until Leppington line is ready),
- a group of workmen were testing points for local air operation in vincinity of the old relay building,
- a group of workmen appeared to be installing cabling for P4 TDI's (southern end),
- some ballast sweeping in vicinity of the old relay building adjacent crossovers.

Based on the Liverpool P4 cut-in, watch for news in March(?) Weekly Notices for activation date of new signal system, P4 and local crossovers.

PS It obviously wasn't the last rail shutdown-weekend, but the last is another one closer.

Went past this morning and definitely nothing visible that has changed. Haven't even taken the covers off the signals that were previously covered (there's quite a few of the new signals on sections of currently unused track that are uncovered and showing red/red).

FYI - two 'new' aerial photos of Leppington and Edmondson Park stations (very early Feb '14) now added on the Gov't's SWRL Project web site today.

Aerial photos of stations are fine, but in a few months? I expect to be able to buy a train ticket and take as many close-up pix of the stations as my heart may desire. The part of SWRL not presently visually documented and otherwise inaccessible even when in possession of a train ticket, is its start, i.e SWRL junction, southern flyover (now otherwise complete) and the nearby viaducts, which would be a great aerial shot. Could someone with clout with the Government or the project (or their own plane Smile ) attend this oversight please?

No crossover there.

Thanks 'Bugnash' for the reply; will have to revise my track diagram and ideas for a Leppington shuttle.

FYI - A March 2014 GTI CU .pdf is now available at the Gov't's Project website, although it _may_ be suffering from C&P errors as it still refers to the Feb shutdown weekend. Of interest are the following activities narratively listed:

"...,HV installation and commissioning. On the Northern Flyover structure construction works will include the installation of rail, the extension of the concrete structure and graffiti removal. "

- I assume the HV refers to the HV power into the Glenfield South 1500v substation;
- The 'installation of rail' and 'extension of the concrete structure' are obscure but _may_ refer to the flyover exit connection to the East Hills Up line(?);
- 'graffiti removal' suggests GTI completion is getting close.

The March 2014 GLRL CU was not available at the time of this post.

Edit - The 'Current Works' page now shows as 'February/March Construction Actitvities', so maybe both GTI and GLRL 'March' continue what was listed for February with a few extra tasks for GTI.

The march SWLR report is now out. The second page has a bit of a blurb about the 60MVA transformer that's being installed. (BTW, when they say it will convert high voltage to medium voltage, it is probably a 132kV to 33kV transformer)

Dickson rd bridge is now re-opened.
Rickard Rd bridge (the one right at Leppington station) is expected to open in April.
Both stations are having carparks and access roads finished, plus internal fitouts and pavers installed.
The two smaller substations had electrical fitout, switch gear installation and communications cabling complete.
The transmission substation still has earthing, lightning masts and SCADA installation to complete.
As far as work on the rails... "Continued installation of overhead wiring, signalling and equipment. Communications backbone installation also continues. Signals testing ongoing."

The 33kV is the usual input voltage for 1500V traction substations, which Denham Court will send to Leppington and EP subs. There is already a substation north of Glenfield Station, and another at Macquarie Fields, so what is the purpose of the Glenfield South substation?, to replace one of these? Could Edmondson Park substation be close enough to Glenfield to power the southern flyover? Getting a train up the flyover would need a bit more current output than the MF sub might have been designed to supply in the original (nominal) flat terrain.

Curious.

At the 'Sydney' end of P1 (Up) at Macquarie Fields the existing signal has 2 lamps in the top cluster (R&G), but the 'new' one to soon replace it has 3 (RYG?); the top 'Y' is used to indicate a turnout, yet there are an additional 2 'new' signals before the turnout just south of the southern flyover ('Up' to Glenfield P1). Can anyone explain why all the new signals?

Curious (again).

I can see two possibilities for the additional substation.
1) With the new Glenfield layout allowing many more trains through, as well as multiple simultaneous trains running in the same direction, the load would increase.
2) One of the main issues with 1500VDC traction supplies is that the lower voltages don't travel so well, so need more frequent substations. It is possible that this is required to power trains halfway to the EP sub.

I suspect that it is a combination of these. The new substation is darn close to the Mac Fields one, though! Maybe they just wanted an upgrade and will rip out the Mac Fields one later.

As far as the up gradient, I would have thought that the rated power would be a function of the trains maximum power usage (i.e. the trains wouldn't be rated to pull more power on the uphill, they would just accelerate more slowly). I could be wrong, though.

I'm pretty sure I saw this transformer being transported along Pennant Hills Road early Sunday (22/02/14) morning.

1) Agreed. Glenfield has doubled its platforms, so twice as many trains can be starting at the same time, so the sub total installed power output would need to rise.
2) Agreed. The typical sub spacing these days is about ~ 7km max, and the high current used also sponsored use of a double contact wire, to ensure 1500v is seen by a trains traction equipment. With two subs on an 11.4 km line, initial impression is that EP ought to be able to supply all the way through the southern flyover, but not having seen a grade profile for the line, I believe it is a grade either side of the freeway tunnel and a climb over the viaducts to the top of of the flyover, so perhaps GS also provides the power for this section as you suggest.

With DC traction motors and starting resistors the starting characteristics were fairly simple to understand, but choppers and invertors in modern rolling stock are a different breed.

Reporting on SWRL (GTI) Progress in March will be limited to guessing. The March CU Update shows no rail shutdown weekend for March, and while I did expect the Up/Down TCO OHW to be finished by Feb 24, a check at Glenfield on the 24th showed some related wires are covered by yellow/black sleeves, which suggests it is NOT completed.

Did note the old Signal Relay building was half painted in a 'Dark Brown' when I passed it earlier this week, so graffiti cleanup may be under way.

"On the Northern Flyover structure construction works will include the installation of rail, the extension of the concrete structure..." remains largely obscure - what 'rail'? (derailment check rails on the bridge portion?) and what 'concrete structure' needs extending?

A piece of the guesswork is to suspect the HV commisioning set for the 22-23 March (also a Sat/Sun) could prove to be a shutdown weekend, but don't quote me. Smile

If BOF is now over his Fast 2nd Sydney Airport Train to Canberra fantasies, and that it appears that Badgery's Creek will finally happen, extending the SWRL from Leppington to the airport site should be a no-brainer.
  normw Junior Train Controller

A check today at Glenfield (8th) revealed the (derailment) guard rails are now in place on both the Northern and Southern Flyovers (did take some pix but no web site). I assume these are the 'rails' to be installed per the March '14 GTI CU; still no idea where the concrete structure needs extendng?

The depot being built on the (now old) construction site adjacent to the East Hills down main looks impressive; I would guess a service point for signals and/or perway for the Glenfield-Leppington region, but will poke about further.

The political system has quite a few of those...what is needed is more 'have-brainers'. Smile

Notice the four (4) platforms.

Notice the "platform screen doors" for greater safety. Wink

The four (4) platforms at Leppington have been a 'known' since construction at Leppington began, probably back in 2012 or there abouts, and mentioned in earlier messages in this thread (always a good read of history).

If, by 'platform screen doors' you mean the hand rails along the platform edges, these are a normal safety requirement during construction, and similar rails would have been in place on the platform roofs when the roof sheeting was being applied. Recently openned platform 4 at Liverpool had similar 'temporary' hand rails from the day the platform concrete edges were first poured until the day before the platform was declared open for train services. Platform edges are really a hazard even for train passengers, but it is one construction workers do not have to be exposed to.

Information that has been shared with me, is that Stage One (Platform 4 and the EHUM from just south of the Souther Fly-over and the Northern Flyover) will open soon, but will not be joined to the existing EHUM until the weekend before it is to Commence operation.

Fact:
Crew Training for this section of track including the flyover will be commencing next week (23/3/14) By way of an instructional video and physically walking the track.
