Tomorrow is the first day since NYD that Caulfield to Westall will be open, so there's a little bit of a breather from train replacements [for the time being]. There's varying locations of closures on varying nights next week from 8pm, and then the first REAL DEAL closure Tuesday 30th January to Wednesday 14th February of which the new Noble Park sky rail station will be open

I saw they said 100 beams done, 70 to go around Murrumbeena, so they will be a while before they will be doing track/overhead there

That's across the road from home. Smile It looks like they are trying to finish installing the spans for the down side first, presumably so they can start working on tracks etc while they finish the up side. Last I saw the up side is only done from Murrumbeena to just past Carnegie - they have a lot more to go! Down is most of the way to Poath Road and most of the way to Grange Road so a lot more done on that side.

Edited: Did a very quick count on the plan and I reckon there's about 37 spans done on the up side. The remaining 63 would all be on the down side.

I had a quick look at how far the spans have been installed at both ends today.

In total there are 86 piers on each side (172 in total) in Area 1 - Caulfield to Hughesdale. Pier 1 is at the Caulfield end.

Down side has spans installed from pier 9 to pier 77. The "ruler" has been sitting on piers 77, 78 and 79 since before Christmas.

Up side has spans installed from pier 12 to pier 59. Another span is being loaded on the carrier and will take it to pier 11, probably before morning. The "ruler" is presently sitting over piers 12, 11 and 10.

Piers 1 - 8 are the double track piers on the south side of the existing line and I don't know if they will use the carrier there. (If they don't I have no idea how they will install them!)

The final pier before the embankment at Hughesdale is pier 86.

So in total 170 spans in total, with 115 spans installed as at 7 pm on 18 Jan 2018.

I also don't know how they will install the end spans - the carrier requires the "ruler" to extend out to 3 piers beyond the location being installed and as yet there is no sign of any subsititute such as scaffolding. There is a fair bit of space at Hughesdale so they could potentially crane in the last ones, but there is not as much space at the Caulfield end.

I am no expert on this, I just watch the big engineering and disaster shows on TV and I've been watching what's happening across the road from home (between piers 72 and 75) with interest. If anyone wishes to correct me on my wild speculations I will welcome that!

Update on Falconlea's excellent report.

At the Caulfield end today they were preparing to install the beam on the Up viaduct between Piers 9 & 10. This would make both the Up and Down viaducts complete between Murrumbeena and Pier 9. I suspect this will be the finish of the straddle crane at the northern end; the Down viaduct has been complete to this point since before Christmas.

I rather suspect the remaining beams will be installed by crane as these represent the ramp down to ground level. Thinking about it, I'm not sure I'd want to drive the straddle crane, complete with beam, down a 1 in 60 grade towards the end of the viaduct...

I only drove past the Oakleigh end. It appears that the Up viaduct has been completed to within 5 or 6 piers of Poath Road. The Down viaduct hasn't been commenced beyond Murrumbeena.

There are no sign of the platform covering at Murrumbeena or Carnegie, but the ground level buildings are well advanced and the platforms are being constructed.

It's been confirmed that the Noble Park viaduct will open to commuters on February 15. This means Chandler Rd, Heatherton Rd and Corrigan Rd level crossing boom gates will operate for the last time before the rail line closure between Westall and Dandenong around January 29.
The Clayton and Murrumbeena viaducts will open on later dates this year, one would predict.

The Clayton section will open mid-April AFAIK. The Murrembeena/Carnegie section is still a fair way off.

I was quite wrong about the installation of beams at the northern end; they are continuing to use the straddle crane. Yesterday or early today the first beam across Grange Rd was installed. This was on the Down viaduct. The Up viaduct had the beam just south of Grange Rd installed today, so the next beam tonight or tomorrow will be the Up viaduct across Grange Rd.

Interestingly, work seems to have been suspended at the southern end. The Down viaduct is still about 6 spans north of Poath Rd, and the Up viaduct hasn't been commenced south of Murrumbeena.

And the carrier was off towards Grange Road this morning with another span.

There are delays at the Poath Road end due to a faulty pier that had to be disasssembled and repaired. I haven't slept well for several nights due to these works.

Does anyone know *how* they are installing the spans given that there is only one "ruler" down at the Grange Road end? And they appear to only be using the Up viaduct to transport the spans. I am guessing that a couple of the spans must have a cross over where the carrier can move to the other viaduct?

The crane can lift the straddle carrier across at Murrumbeena

It's departing down one track and then installing on the *other* track. I wanted to know how they're doing that trick - I know they lift it over at Murrumbeena but that's not what's happening.

This morning I purposefully went on a stopping all stations train replacement Westall to Dandenong so I could travel alongside sky rail and am wondering why trains aren't operating sooner than Thursday due to a 3 carriage Siemens operating a few test runs back and forth between those stations

Hmmmm, had a look at Twitter and searched "skyrail". Some good photos on one tweet today.

But lots of 'No Skyrail' hysterics and spam too unfortunately.  That's their democratic right, even though their astroturfing tactics are rather obvious...

Yeah I saw the photos from vicsig twitter account.

Apparently I've been blocked by few of those anti-skyrailers. Shows how ignorant they are.

I hate the stupidity that is "no skyrail". If you choose to buy a house right beside a railway line, it is surely assumed that there will be constant noise, occasional maintenance and certainly criminals searching for graffiti-ing opportunities (regardless of the presence of a bridge). And then when an elevated line is constructed (surely, if they were smart and considered their local crossings to not be permanent), they complain as if they are building skyrail on their land. Honestly, if you by a house next to a railway, don't expect the railway to stay the same! And then there are the 'poor' people of Carrum, struggling to enjoy the privileged of living in a beach-side suburb, wondering why a government doesn't spend billions of dollars on a solution about as likely to survive climate change as the outer polar ice caps of the Arctic Circle. And surely noise cannot be an excuse. The new technology actually reduces noise, and there is nothing like blasting bells at 12:00 at night. Yes, it is within their right, but surely they could have foreseen something of the like coming!

I've wondered the same thing, but haven't been in the right place at the right time to find out.

As for the ruler, I've been assuming that they simply jack it from one side to the other (both beams are now on the same pier head).

I wonder if there are or will be paint vapour detectors under the viaducts.

They've wasted no time pulling out the old infrastructure in the Noble Park section. The tracks, sleepers, wires and stanchions are pretty much all gone!

One of the Governments main selling points Is the curation the open space under and around the viaducts, so they want to show the public that this Is well and truly under way, along with dismissing noskyrail propaganda claims (like their claims that diesel trains will be unable to run on the viaducts and will still need the ground level tracks)

Gotta love their scaremongering claims about diesel locomotive fume emissions (they don't seem to exist when a diesel locomotive climbs out of a trench)

As at today, the northern end of the viaduct is just about down to ground level. There are just two more beams to be placed on the Down viaduct, and three on the Up viaduct. The 'ruler' is located to install the next beam on the Up viaduct, and I would expect that to happen today or tomorrow.

It's not clear how the last four beams will be placed. The front most support of the ruler is on the last pier, so if any further beams are placed using the straddle crane the supports would have to be placed on the abutment (or beyond).

They are currently working on the side walls of the embankment at Caulfield beyond the abutment. They were piling today.

And overnight another span was placed in Murrumbeena. Clearly part of the new Hughesdale Station with all the cut-outs on the side.
