Hey mods, the Suburban Rail Loop thread has disappeared, it still appears in Google results however.

(original link: https://www.skyscrapercity.com/showthread.php?t=2117418)

Anyhow - geotech investigations have started in Box Hill

https://www.premier.vic.gov.au/suburban-rail-loop-site-investigations-start/

Suburban Rail Loop Site Investigations Start

The next stage of Suburban Rail Loop is now underway with geotechnical work beginning at Box Hill.

Premier Daniel Andrews and Transport Infrastructure Minister Jacinta Allan visited the site where the drilling has started, which marks another step towards transforming Victoria’s public transport system.

Site investigations at Box Hill signal the start of a program of ground works across Melbourne’s southeast that will help understand ground conditions and plan for the new underground alignment and station locations.

The geotechnical investigations involve drilling boreholes of depths between 30-60 metres. The rock and soil are then tested for composition and stability, with each site taking around two weeks to analyse.

The geotechnical investigations are a vital part of development and technical work that will determine the stages and timing of the project, and how it will be built.

The Suburban Rail Loop will connect Melbourne’s middle suburbs to priority growth precincts, and link all Victorians to major health, education and employment centres.

The 90-kilometre rail link will connect every major railway line from the Frankston line to the Werribee line via Melbourne Airport, easing demand on existing lines and shifting more Melburnians out of their cars.

When finished, it’ll mean that people living in the regions won’t need to travel through the centre of Melbourne to access jobs in growing economic precincts outside the CBD.

Victorians are encouraged to have their say on all elements of the project through a community survey and local pop ups have begun along stage one of the Suburban Rail Loop.

Construction on the first stage of Suburban Rail Loop is expected to begin in 2022. To have your say visit railprojects.vic.gov.au.

Quotes attributable to Premier Daniel Andrews

“We said we’d get the Suburban Rail Loop started and that’s what we’re doing – with geotechnical work now underway in Box Hill.”

“Suburban Rail Loop will change the way we move around Melbourne, slashing travel times and better connecting people with jobs, education and other vital services, wherever they live.”

Quote attributable to Minister for Transport Infrastructure Jacinta Allan

“Whether it’s removing level crossings, the Metro Tunnel or North East Link – we’re getting on with the projects that Victorians voted for and need.”

From the General Melbourne thread.

SRL Cheltenham/Southland to Box Hill, and MARL will commence in 2022.

The rest of the SRL will be a project for the 2030's.

.....is what they are saying.

SRL from Box Hill to Cheltenham is a minimum of 21km of underground rail. If they start works on the ground by 2022 my guess is that it would be prep works only (like what QLD did with CRR).

No way this will have a detailed design and ready to start by then.

On another point, I wonder if it would be better to have the SRL commence at Moorabbin Station, then Huntingdale, Monash, Glen Waverly then Box Hill. Similar distance but more opportunities at the stations.
21km is about 25% longer than Sydney Metro Southwest's 15.5km. SMSW also has 7 underground stations (Crows Nest-North Sydney/Victoria Cross-Barangaroo-Martin Place-Pitt Street-Central-Waterloo) and SRL1 would have 6 - (Cheltenham/Southland-Clayton-Monash-Glen Waverley-Deakin/Burwood-Box Hill).

I don't know how strictly this was adhered to but Sydney Metro conveniently puts these indicative timeframes on their website.



"Start by 2022" is convenient spin for the government but if it really is just preparatory works, who cares really, the shovels come soon after.

Worth noting that SRL is at roughly the point Sydney Metro City/SW was in about 5-6 years ago (2013-2014)

First significant works on that were in 2018. So 2023 start of genuine construction sounds feasible. Funding/business case permitting

2022-2023 also squares with the major wind down of construction activity on Melbourne Metro 1 (like how 2017-2018 was the major wind-down period for Sydney Metro Northwest) - that's assuming all the major civil works are done by late 2022/2023 and it's more about fit out and testing by then.

By the by, I assume most people understand the significance of 2022, by if not - it's the next Victorian election year (Last Saturday in November 2022).

I think we should be tendering this massive project out to the Chinese on a BOOT basis.They will most likely have it done in 10 years!

In the general thread I said.........

"Well I guess time will tell won't it. What I'm certain of is that the State Government will have full construction contracts signed and work underway before the 2022 election. It was taken to the 2018 election as policy.

It will also have MARL underway by then, completion 2031, and North East Link well progressed, completion 2027. Mornington Peninsula Freeway extension and Westgate Tunnel will be completed. But I digress."

I was then asked what made me so certain? The answer is the political necessity for the State Government to assist in its re-election, as Tayser said above.

There are already a large number of staff being employed for this project.

I think having MARL underway as the first part of the SRL and the next section clearly in the pipeline (as in planning approval and enabling works) is easily enough for them to spin to avoid any political risk, and that's eminently achievable

I know there are lots of people working on it, but there's a lot to do. And most of them are things that are hard to accelerate or compress - doing enough design to put together a business case, putting together the business case, trying to get the business case approved (both at state level and federally), doing further design for planning/environmental approvals, putting together the approval documents, putting them on exhibition, dealing with feedback and updating them, producing packaging strategy for procurement, producing procurement documentation including reference design, putting packages out for tender, receiving evaluating and negotiating tenders.......

For an "easy" railway that's about 3-4 years worth of work. Say 2-2.5 years fastest possible from investment decision (ie business case approval). This isn't an easy railway. It will go through an urban area with a sh1tload of stakeholders, multiple options on sites for tunnelling, stations and access, and will require some creativity in the business case as it needs doing in sections but will only really deliver benefits when finished, which combined with discount factors makes for a stretch on a BCR

The map's been (ever so slightly) updated to include Wyndham Vale.

^^ My suspicions are looking more and more likely.

Noted, but there is political need and there is reality. Unfortunately, sometimes the two do not meet.

If MM2 gets done and handles all Geelong trains, that alleviates the need to quad the current Tarneit line. It could just become SRL with interchange for the city.

I think you'd need to quad it regardless. SRL and Melbourne City Trains. Or SRL and RRL trains.

Either that or you have a spur and have half the Wyndham Vale trains go to the city and the other half to the airport with half the airport trains continuing around the loop.



I think they will end up with RRL as Melbourne and SRL (4 track) with Geelong, Werribee and Freight through Werribee (6 track ultimately if freight need 2 tracks).



Anything can happen though.

Suburban Rail Loop work begins as geologists drill deep for $50b line
July 23, 2019 — 3.53pm Tina Jacks

Deep drilling that will help pinpoint the locations of stations on the $50 billion Suburban Rail Loop has begun as the initial steps are taken on Labor's signature rail project.

The first sign of works on the Suburban Rail Loop are now under way in Box Hill, where boreholes up to 60 metres deep are being sunk to test rock and soil for composition and stability.

It's one of hundreds of geotechnical drilling sites that will dot the 90-kilometre largely underground rail line through Melbourne's middle suburbs, connecting nearly every metropolitan train line in a ring around the city.

The project will include 16 stations, with a new map of the project released on Tuesday showing a potential new interchange station at Wyndham Vale.

I'm almost certain they will announce some "construction" though. Just to tease and just release the tenders well after the election.

Its odd, I was the OP for the first thread, I didn't delete it.


Anyway, I'm surprised they still have Glen Waverly included. I know it is subject to change and all and the whole western section is still to be refined as it'll be the last stage.

Has there been much talk of a real increase in density around each of the stations? Especially the interchange stations.

^ this is why it's a **** up of epic proportions for the deletion of the old thread, this was discussed at long length.

In short - Monash, La Trobe and Sunshine are three NEICs that have somewhat advanced planning in place to see major uplift in floorspace across commercial/jobs, residential and retail.

Whitehorse CC / Box Hill development unit within council have been nagging to get the Box Hill Interchange rebuilt/altered no doubt in conjunction with the centre operators. Plus Box Hill doesn't need much of a nudge to see new development (it's already happening).

And the various other councils (Monash, a big one) already have other strategies in place. That said, there's no doubt going to be changes over the next few years but it's not as if this is all starting as one giant low-density suburban mass with zero plans to change anything.
