The overpass near Yarraman is south of the existing line, but the raised rail around Noble Park is north of the line. It's probably easier to have a short section at ground level than to build over the current line.
I'm not sure why they're building the new Noble Park station on the northern side, but they'd have to acquire some properties if they wanted to build one long section on the northern side between Sandown Park and Yarraman.

Will any stations directly above streets replace ones next to level crossings. That's another advantage brought by grade separation.

They don't want station platforms to span roads where possible. Easy enough to jump the tracks and jump down onto the road.

Only daredevils would do that.

Most likely its to connect it to the waterpark and skatepark, probably to get that feeling of skyrail being a recreation area or something.
Weather its better then where it is at the moment or not is up to debate.

Probably to keep the viaduct as far away from Lightwood Road, where there are many houses that could of been effected by the blocking out of the North sun.

Look at Richmond station. Part of it is above Punt road, and it can be easily accessed from both sides of that road.

Engineering Question. How will the rails be laid on the elevated sections? Will they be directly cliped to the concrete beams or will they be on sleepers on ballast? Does anyone on here know?Very Happy

I think this video from LXRA might help explain things too as it shows how the track will be constructed on the viaducts.

People might be interested in an update as to how far they have got on the Caulfield - Oakleigh section.

On Friday, 17.11., they completed the Up and Down viaducts over Koornong Rd, Carnegie. They then erected a further two spans on the Up viaduct towards Caulfield.

The construction beam for the Up viaduct was then removed, taken to bits, moved back to Murrumbeena, turned end for end, and re-erected to start work on Down viaduct towards Hughesdale.

Since then the Down viaduct has been extended about four spans towards Hughesdale.

At the other end, the Down viaduct was completed today to the portal structures just south of Grange Road. I would suspect that the remainder of the Down viaduct at the Caulfield end (where it crosses the existing lines and the ramp to ground level) will be erected by crane. I would guess they will now move the construction beam back to Carnegie and recommence work on the Up viaduct.

There's still quite a bit of work to do, but it feels like the end of the erection of the viaduct is in sight.

you can find damooops's photos here -


I'm assuming that this photo by damooops shows the last pylon north of the track and that the next few will cross over the current lines and continue on the south side.

Pretty much.

The photo is taken from the northbound service lane of Dandenong Rd just south of Grange Rd.

The span is resting on the first of two portal supports which takes the Down viaduct across the two existing tracks to the south side of the reservation where the ramp will be constructed. At this point, the span is already partially over the existing Down track.

After having another look at damooops's photos I've concluded that at least two of the pylons that will take the down skyrail track over the current tracks are up (if that makes sense).
That means that there about ten more pylons to go for the Grange Road section of the down track which are yet to go up.

Does anyone else think its stupid that they put all that scaffolding around every pylon? Imagine how much time must be spent dismantling & reassembling the scaffolding.

Surely could have been done better.

Line duplication work is underway between Dandenong and Dandenong South

I wasn't aware of this. Is this part of the level crossing removal project? Is it part of the scope of works for skyrail? Anyone got any ideas?

They're a safety system, which is why they're on every pylon. You need a way of getting workers off the viaduct spans in a hurry. Ladders only work if you're fully ambulatory (which you may not be if you need an ambulance). Cherry pickers/mobile scaffolding are slow and never around when you need them, so they don't cut the mustard either.

Braddo,
What would you propose instead?

Gauntlet

No, I believe that all the pylons are up. The tops of the pylons in the final (initial?) section are wider than the pylons further south and will take two beams.

There are two portal structures which span the existing up and down tracks. This represents three spans that take the Down viaduct across the existing track. North of of these spans, both viaducts will be squeezed into the gap between the Up line and Lorne St/Girdwood Ave (I would suspect that the Down viaduct will foul the existing Up line).

Have you seen a house being built recently? Modern OH&S frowns on unguarded heights.

And I guess you haven't seen the cricket team of people on top of the pylons when they are erecting the spans.

In practice, putting/up removing scaffolding is quick and easy for the scaffolding contractors. It's certainly far cheaper than an accident. And easy access to the top of the pylons speeds up the work - which is where the real cost is.

Thank you. I had no idea at all about this! I think it's because I assumed the Dandenong Rail Project (or whatever it is marketed as) was just Skyrail + Platform and Signalling upgrades.

Hi - it has been a while since anyone updated the progress.

I have been away and saw the LXRA is not really giving any updates either.

The PTV apps and website indicate busses until 14 Feb between Dande and Westall.  Does this mean they are finishing the Noble Park viaducts? Last December it was seemingly advanced.  All spans are in place decking and ramps/stations being built.

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
