Melbourne Airport Rail Link

Location: Dubai UAE
From Mercer Dr
- Follow Airport drive in median on viaduct
- Straight over the top of Value Car Park
- Just prior to Airport drive, slight curve to right to go over corner for Merc service centre to aim for Macca's in distance.
- Holiday Inn kept to left
- Left turn to go in between carpark and Qantas Terminal over the top of the surface carpark.
- All on viaduct like Brisbane
- Direct air bridge access to International and Qantas,
- Bit further to Virgin using the existing airbridges
- T4 access via Virgin

Terminus station, no hope of extension. Agree if you want extension you need to go UG, not sure the trhough trains need to access the actual airport station though as airport users from north would be very low.

Job done.
Two of the golden rules of modern railway design are straight platforms and min 200m radius curves, both of which can be ignored/exceeded, but there are consequences.

The awful Rushall curve is something in the order of 130m radius and the problematic Sydney Olympic Park curves are around 150m.

Assuming airport trains are the same length as 6 car suburbans, approx 180m of straight track is needed for the platform(s) which is just doable assuming the station is between the Park Royal and T2. Avoiding the Nth corner of the Park Royal and the high part of Melbourne Drive, and squeeze in a reasonable curve would be quite clever.

If only provision had been reserved for rail access...

Very Valid points

The proposal I suggested was a straight section for the station and assumed cross overs to fit is at least 300m long. On a compass heading looking along the station would be around 45 degrees west of north.  ie SW to NW alignment. Curves should also be ok.

You mean over the carpark between the Park Royal and Melbourne Dr with the buffer stops adjacent to Departure Rd outside T1? Quite doable, although I would advocate to place the platforms on the same trajectory but on the other side of the hotel as being a more central location.

Then by going a little higher to clear the terminal buildings, and on viaduct across to the Western side for the proposed international terminal. Laughing

The trains will be 10-car going through the metro tunnel, so you need platforms length of at least 220m (same as the metro tunnel)

There has been no mention of Stations being provided at Airport West or Keilor East By the Government.

Cant remember who I saw the information from, but they are leaving provision for future stations in the documentation.

Correct. There is only one provision of a station at Airport west, just past Fullerton road, in the planning documentation that Marcus Wongm checked out via the Tenders website.

And that's it.

I still can't get over the expense and the time scale of the Melbourne Airport Rail Link. Western Australia have nearly completed 8.5 km of track, 8 km in tunnel, 3 new stations, 2 underground taking 6 years to complete at a cost of $1.86 Billion.

Whilst in Victoria, 2 couple of bridges, sky rail, using existing corridors and 1 new above ground station, is going to cost $10 Billion and take 7 years.

With this massive descope I hope that $10 Billion gets whittled down to $1.5 to $3 Billion. And it should be able to be completed at the same time as the Melbourne Metro.

Yet to see official comment on time or budget, just that up to $10B was pledged to build it. Until the tenders have been awarded for $10B worth of works, I'll hold my thoughts on the project.

It is just political commitments, no budget yet. Looking at closer to $5B, most likely to be less than this. What will happen to the remainder of the commitment is anyones guess. The Western Rail Plan springs to mind.

Betting we'll reach 100 pages before any construction begins.

Yep. Aided and abetted by over engineering of a branch line.

Another step on the way for the airport.  The mystery of what will happen at the airport remains for a further announcement.

Tenders have been let for the new bridge over the Maribyrnong, therefore may I suggest the hardest part has been resolved with an obvious $$ commitment from state and federal governments.

I'd still be very interested to see what future design /provisioning is feeding/ has fed the sunshine Track layout / design (if any). Really getting on my foaming / conspirator hat I wonder if the relatively disconnected new cross platform transfer at sunshine is well away from most of the existing station because re-design/rebuild of that is being considered later on w WWP.

Although realistically probably being done because its cheaper and easier not to touch or alter what's there.

While the new Maribyrnong viaduct is the largest new structure in terms of visual impact for the project, I'm not sure it's the most difficult. I think Goose is on the money here. Threading the new services through the Sunshine - Albion gauntlet quickly and smoothly and maximising the ability for passengers to make quick changes at Sunshine, and not stuff up future capacity improvements, is the difficult part.

It’s probably a good thing that the governments seem to want to do this on the cheaper side, that is, not adding new tracks between Sunshine and the CBD. It’s not required if you have ARL being an Airport - Sunshine shuttle, atleast in peak. Install a turn back between the UP and DOWN tracks before WV / Melton join MM1 mainline and then you can have for example 10/10/10TPH WV/Melton/Sunbury through MM1 in the peak, with 6TPH Airport shuttle. Then during the quieter periods, it can be fine to have Airport trains through MM1 as the MM1 won’t be at track throughput capacity.

The point is, that we don’t require new tracks between Sunshine - CBD, we will have the track capacity, if we have ARL as a shuttle during peaks.

MARL as a shuttle during peaks is not a good idea as that is when most international flights arrive and depart...

We don't need another track pair between Sunshine and the CBD because we already have two: if you electrify RRL out to Melton and WV as part of the Western Rail Plan you could get 24 (MM1) + 20 (RRL) trains through Sunshine without a sweat.

That's easily enough capacity for Sunbury, Airport, WV, Melton, Ballarat and Bendigo if you're running the big HCMT.

Not to mention business travellers, if you want any hope of capturing any of that market then you don't put obstacles in the way like making people change trains

44 TPH? how do figure that if they don't quad the tracks to Melton and WV as planned

Sunbury (12), Bendigo (4) and Airport (6) come into Sunshine via Albion (or over it), giving you 22 TPH.

Melton (6), WV (6) and Ballarat (4) come via Deer Park, adding another 16 TPH into Sunshine.  There's even some more capacity there for extra Melton services or some stray Geelong trains to come by.  The quadding out to Deer Park would only be to segregate VLine and Metro trains through that section to and untangle some of the crossing paths before you hit Sunshine.

But other than that, there's plenty enough tracks out there already to move many thousands more passengers so long as we're setup to actually use them.
