Melbourne Suburban Orbital Rail - Mapping the Route to Success - Part 1 - Southland to Broadmeadows



"Melburnians, it's a GREAT time to be a suburban orbital rail enthusiast."  
- The Bloodied Wombat, March 13, 2017
So you can imagine what the last fortnight has been in Wombat-ville. The Andrews government's commitment to commence planning for a "suburban rail loop" is most of our collective prayers for Melbourne answered in a frothing torrent of holy water.


"BAPTISE this city, Mr Premier, with your heavy rail holiness!" 
- The Bloodied Wombat, August 28, 2018.

And while we always thought the politics of such a project would be good, we've been blown away by the real enthusiasm with which the public has embraced the vision. Alan Davies has been telling me this was a stupid idea for as long as I've been discussing it, but his recent commentary has really been the outlier in pouring scorn on the project's mooted benefits.

I'd like to return specifically to some of Alan's concerns in the concluding blog to this series. But first, let's take a look at the project as it is currently proposed, and make an assessment of the logical "next steps" in project planning to ensure we return maximal benefits from the project for all Victorians.



  • In part one here today, we'll look at the majority of the network, and the portion most likely to be delivered as tunnel - from the Frankston line through to Craigieburn. 
  • Next week, we'll look at the remainder of the network through the western suburbs and how the delivery and timetabling options and imperatives out there actually look very distinct to the underground portion of the network.
  • In part three we'll look at some rudimentary cost-benefits and respond to some of the common critiques of the plan as well as look at some further incremental developments to consider to address any major goals this orbital rail plan is unable to, and so deliver a maximum benefit metro style heavy rail system for Melbourne.




i'M SORely what Melbourne needs 


For starters, we need to do something about an acronym. The notional Wombat project suffered a little from nomenclature overload, usually going by some variant of "Urban Orbital Rail" and "Suburban Rail Loop". Other commentators seem to have just settled for the obvious - the government document is entitled "Suburban Rail Loop Strategic Assessment", so SRL it is.

I'm probably a little bit tragic in this regard, but I look at that acronym and the only words that enter my dyslexic head are "Stevie Ray Vaughan". So I think we can and should do better. A loop is necessarily orbital, so we can turf one of those two words, and I think it needs a bit more LOCAL, yokels. So I'm going with Melbourne Suburban Orbital Rail or MSOR, and you'll just need to adjust your sets accordingly.


Orbital Rail Benefits - Recapped


It's all about the network effect. Human civilisation's greatest quantum advances have all taken place as a result of technology that enhanced our ability to network together as human beings. The invention of railroad itself is but one critical illustration of the phenomenon.

We've seen in an earlier blog that Melbourne's existing employment centres map very neatly to the established heavy and light rail network (image below), and it's important that we state from the outset that the PRIMARY goal of MSOR, in order to make the project stack up cost-benefit wise must be the facilitation of transport movements radially IN to designated suburban employment centres.

Melbourne Employment Densities and Centres with Tram/rail Networks

The main benefit of the policy - the entire point of spending $50bn is to purchase the necessary enabling infrastructure to allow us to build the ever more mythologised "20 minute city". The point of this MUST be a radical re-envisaging of the MAJORITY of suburban employment journeys to enable a significant mode shift to public transport.

We've estimated previously that as many as 200,000 more Melbourne commuters hop in their cars  DAILY for the journey to work than their Sydney counterparts, and tendered significant evidence that the less radial nature of that city's heavy rail network was the most obvious source of this.

But we also simultaneously discussed the ways in which Sydney has done a far better job of the planning side of the equation - on facilitating remedial land uses and attracting employers into rail-enabled locations.


The real beauty of orbital rail as imposed on the existing radial network is that it creates innumerable opportunities for multiple heavy rail "spokes" to operate radially IN to the new suburban employment centres, over-writing Melbourne's current hugely dispersed suburban employment patterns with a new map that creates a critical mass of employment destinations walkable to heavy rail stations.

And where the heavy rail network previously left enormous public transport blackspots across Melbourne's eastern suburbs, the networked, web-like lattice into which it is transformed by MSOR means that vast swathes of the east in any given direction are now just a few train stations from the new employment centres, whereas previously a commuter in Box Hill would have needed to travel in to Richmond and then out again to get to Glen Waverley, around tripling the necessary travel distance versus car.

That this is not a high demand journey today is not the point, the above shows exactly why the demand isn't there.

Wombat's Melbourne Suburban Orbital Rail Route - Southeast (orange)

We're planning here for Melbourne 2118, from which vantage point, this project will be deemed to have paid for itself several times over. In the same way we'd decry the insanity of ripping up any of our established lines today (and again, the Upfield line would never have stood up to Infrastructure Victoria's methodology if proposed today, as they would assume it would cannibalise 60% of its ridership from the Craigieburn line).


Not Because It's Easy, Because It's Hard


It's very important that we convey that it is NOT POSSIBLE to do the cost-benefit calculations on MSOR, without first calculating the potential benefits for re-shaping land use, employment and transportation patterns all along the corridor. And you CANNOT do that calculation without doing ALL the detailed planning on exactly where the stations are going, how much viable land exists around the new station for consolidation into an urban activity centre, what the potential of that location is as an employment destination, and so on.

In short, the potential of MSOR is less as a pure transportation project and more as a tool to guide land use and strategic planning. Because if history teaches us humans anything - we have two great assets as a species which have enabled all the marvels of our civilisation down the ages. One of those is our ability to network together with our fellow human beings. The other is an ability to plan collectively and work strategically towards a long term goal.

We've only got to where we are as a species by incrementally envisaging better worlds in exactly this fashion. MSOR is a project that dials in a very specific vision of a better world and then goes about planning for it.

Thus is Melbourne Suburban Orbital Rail the very acme of visionary, big picture human undertakings such that truly elevate one's eyes to the horizon, that actually do make a body ever so slightly proud to be a tiny chapter in humanity's infinite history.


Optimising the Route


The initial Strategic Assessment provided by Development Victoria leaves largely open the question of how many new stations will be included in the project, instead nominating a number of broad locations that are intended to be served, as well as indicating the likely interface stations with the existing network.

So, let's look at the Wombat-optimal suggested solutions to some of the core issues. Let's map out an actual proposed network, starting in the Southeast.


Our considerations here are really threefold - to cater to established employment centres currently poorly served by public transport - to facilitate enough new employment centres in order to render the 20 minute city concept feasible - and to provide new commuter stations in existing rail black spots.

We raised in an earlier post our concerns that Plan Melbourne actually fails to designate enough activity centres with enough geographic spread to come close to enabling the 20 minute city it waxes so lyrically about. That concern was overlaid by a sense that not much actual practical policy existed to facilitate the creation or agglomeration of employment or activity centres outside of the small number of headline locations.

We strongly suggest that enabling legislation should be considered for this project which grants full control to the Planning Minister for any planning issues within specified distances around the station sites - with their scope/size roughly scaled according to the 'site potential' ratings suggested below. We'd suggest doing the same for ALL the station sites in yellow and red in the map above.

We would then suggest either a new standalone body, or something within Places or Development Victoria which is responsible for involving stakeholders and developing masterplans for each of the zones, which may or may not have some responsibility for actual land acquisition or consolidation of sites as necessary. It would ideally have a charter to ensure that sensitive or heritage neighbourhoods were preserved, and that larger scale or higher intensity development were focused away from residential areas, but the body's charter would essentially be to develop these areas as employment zones.

Where the government has already nominated value capture as a key potential funding source for the project, we'd suggest you've already taken several large steps towards the need for just such a body or bodies to be established anyway.

Finally, we'd LOVE to see some sort of incentive scheme for large employers currently located a long way from public transport be facilitated to relocate to these new activity centres, and the owners of those large industrial sites be given incentives to redevelop those as residential or other beneficial re-uses.


Which Way South?


Regular readers will recall that the Wombat Plan last left this concept with two feasible N-S routes through the eastern suburbs - an inner AND an outer connection and actually advocated the staggered construction of both. The inner route is largely the one as put forward by Development Victoria. The outer route ran via Doncaster to Ringwood then on to Knoxfield, Dandenong, Braeside and Mordialloc.


The outer route was mostly about enabling rail to those several existing centres, which it should be more than a footnote here, are still probably crying out for some form of enhanced public transport solution on the basis that it's much harder to start an entire new employment centre than to better plan for an existing one.

I'm a little heretical amongst transport buffs, in that I view "park and ride" models for heavy rail into suburbia as a very major success factor in improving the overall mode share for public transport in Melbourne, and accordingly the park and ride potential of the various sites is something we'll be considering in some detail.

I should apply my usual caveat in that the first-best option is obviously having suburban bus or even new light rail services operating super-frequently in to the station from local destinations as feeders to the heavy rail system rather than cars. The extent to which further such enabling policy were put in place would actually have a serious impact on the size of the potential benefits column for MSOR, and so obviously the issue warrants addressing.

But one of the issues this project contends with is that it is retrofitting a european style heavy rail metro into areas with significantly lower population densities than much of Europe, and in order to plan realistically for final yards travel in a city that has never had a good relationship with its suburban bus network, we simply need to factor cars in for the foreseeable future.


Optimising the Station Locations


Urban Melbourne recently carried some good commentary showing what the development pipeline looks like in the suburbs slated to receive MSOR. It can be quite illuminating to read alongside my proposed route. When you get a sense of the quantum of change that is already happening, the benefits of this project appear to be as much in being able to actually take direction of that change as they are in facilitating anything new.


SOUTHLAND STATION - FRANKSTON LINE JUNCTION
Site potential: A
Park and Ride Potential: B
The first question arises at the bottom of the 'clockface'. The Strategic Assessment resolutely states that the route is intended to meet the Frankston line at Cheltenham. This has, however, widely been interpreted as actually meaning "Southland" station, and we would very much encourage the latter.

One need only look at the land usage around the shopping centre, even before thinking about further possible apartment towers on top of the shops to know which site has the greater redevelopment potential as an employment/activity/residential centre. We embark at Southland.

Unlocking the park and ride potential of the site, given it is surrounded by residential areas would be a key success factor, and this would obviously be dependent on arriving at a mutually beneficial arrangement with Westfield to utilise the existing parking areas.



MOORABBIN STATION
Site potential: B
Possible Location: Blamey and Nelson Rds
Park and Ride Potential: D
Moorabbin represents one of the few properly established existing employment centres that we are adding to the heavy rail network, so the proposed location is really at the heart of the industrial zone.

We would suggest significant scope exists, given the large nature of the landholdings in the area to create a small central retail/hospitality zone around the station, but this would not be an attractive location for residential redevelopment at scale. Moorabbin's role would remain primarily as an industrial-style employment zone, and as such park and ride is a lower priority at this location.

SOUTH OAKLEIGH STATION
Site potential: C
Possible Location: Huntingdale and Centre Rds
Park and Ride Potential: B
South Oakleigh is currently a small scale employment zone, which has appreciable redevelopment potential for potentially some more intensive scale office and retail developments around the new station. It is also bounded by significant residential areas, so we would suggest some property acquisition to enable construction of a park and ride structure would be a key success factor.

CLAYTON STATION - DANDENONG CORRIDOR JUNCTION
Site potential: B
Park and Ride Potential: C
This station has always been at the fringe of the actual employment zone, so its catchment contains a mixture of residential and commercial sites with some consolidation potential as the broader employment zone develops.


MONASH UNIVERSITY STATION
Site potential: D
Possible Location: Around the site of the current bus terminus at the Southern end of the campus
Park and Ride Potential: N/A
The core reason why this station has scored so low on the site potential rating, is that locating the station well for on-campus purposes renders its potential to cater to surrounding residential and employment areas minimal, and because we can't be stopping the trains every 500 meters, forces us to place the second new Monash precinct station in a sub-optimal location for unlocking the maximum potential value of the precinct.

The potential to reduce car dependency amongst the campus' 30,000 odd students and academics is significant enough that these issues are obviously unavoidable, and accordingly park and ride would be inappropriate and unworkable here.

MONASH NORTH STATION
Site potential: A
Possible Location: Dunlop and Springvale Rds
Park and Ride Potential: B
Again, this is probably not the optimal location from a broader precinct planning perspective - so if forced into a site like this, the precinct planning should obviously do what it can to try and develop something of a walkable town centre in the vicinity the station.

GLEN WAVERLEY STATION - JUNCTION
Site potential: B
Park and Ride Potential: C
An established site obviously, does a reasonable job catering to the adjacent Glen shoppping centre, and has a reasonably good residential catchment with a small number of commercial sites nearby providing some redevelopment opportunity.


WAVERLEY NORTH STATION
Site potential: D
Possible Location: Springvale Rd
Park and Ride Potential: B
An entirely residential area, this station would be a purely commuter station, and therefore sufficient landholdings to enable appreciable park and ride would need to be considered.

BURWOOD EAST  STATION - #75 TRAM INTERCHANGE
Site potential: B
Possible Location: Burwood Hwy and Springvale Rd
Park and Ride Potential: B
A great opportunity to develop a more pedestrian-friendly mixed use zone around this intersection, where the 75 tram also forms another two "spokes" into a possible employment hub, and where the size of the land holdings thereabouts offer decent scope for renewal, we would urge strong consideration be given to giving this potential employment hub much more focus than it might appear to warrant at first glance.


BLACKBURN STATION
Site potential: D
Possible Location: Blackburn Rd
Park and Ride Potential: B
An entirely residential area, this station would be a purely commuter station, and therefore sufficient landholdings to enable appreciable park and ride would need to be considered.

MIDDLEBOROUGH STATION
Site potential: C
Possible Location: Middleborough Rd
Park and Ride Potential: B
Another site with some established commercial/industrial and good potential for an actively planned mixed use precinct.

BOX HILL STATION - LILYDALE/BELGRAVE JUNCTION - #109 TRAM INTERCHANGE
Site potential: A
Park and Ride Potential: B
Box Hill station, as poorly integrated as it is with the existing shopping centre and bus/tram interchanges, presents a real opportunity, if the long mooted complete re-build of the thing were still on the cards, then Box Hill unquestionably has the greatest potential of any eastern suburbs site on the MSOR for an effective high density residential, office and retail hub.

However, the issues relating to transport connectivity would need some really good planning around them to maximise the opportunity here. We should also seriously consider the extension of the 109 tram along Whitehorse road to provide a new rail "spoke" into this highly significant potential activity centre.


SPRINGFIELD STATION
Site potential: D
Possible Location: Springfield and Dorking Rds
Park and Ride Potential: B
An entirely residential area, this station would be a purely commuter station, and therefore sufficient landholdings to enable appreciable park and ride would need to be considered.

Specifically situated to titillate Simpsons fans.

DONCASTER STATION
Site potential: A
Possible Location: Shoppingtown
Park and Ride Potential: A
Another established shopping centre and major bus terminus with significant surrounding residential, including some medium-high density as well as commercial and industrial. Excellent potential for effective creation of a medium-high density mixed use zone, which would posit interesting challenges in needing to make an effectively private space (the shopping centre) the town centre.

WEST DONCASTER STATION
Site potential: C
Possible Location: Doncaster Rd & Eastern Fwy
Park and Ride Potential: B
Some small scale nearby retail, but a mostly residential area, and thus this would primarily be a commuter station.


BALWYN NORTH STATION
Site potential: D
Possible Location: Bulleen Rd & Eastern Fwy
Park and Ride Potential: B
An entirely residential area, this station would be a purely commuter station, and therefore sufficient landholdings to enable appreciable park and ride would need to be considered.

HEIDELBERG STATION - HURSTBRIDGE JUNCTION
Site potential: C
Park and Ride Potential: C
As an established station servicing a sizeable mixed use retail, commercial and medical precinct, it offers limited scope for additional park and ride, nor would we really want to encourage that near an established retail shopping strip.


HEIDELBERG HEIGHTS STATION
Site potential: C
Possible Location: Edwin and Bell Sts
Park and Ride Potential: B
Largely residential area, some small scope for enhanced commercial along the main roads in the vicinity.

NORTHLAND STATION
Site potential: B
Possible Location: Northland S/C
Park and Ride Potential: C
Largely established industrial area, but as industrial does offer reasonable scope for future precinct planning. A core challenge here again would be to effective activate anything beyond the shopping centre - perhaps the best realistic outcome would be a mixed use development of the existing shopping centre.

WEST PRESTON STATION
Site potential: C
Possible Location: Waterdale Rd
Park and Ride Potential: C
This is an existing small scale industrial area south of La Trobe University, and as such offers tremendous opportunity for creating a transport-oriented employment precinct either allied or independent to the University


LA TROBE UNIVERSITY STATION
Site potential: C
Possible Location: Somewhere near the Agora
Park and Ride Potential: N/A
The issues here are similar to Monash, except the larger distances mean that station location doesn't really force compromises elsewhere, although it won't be a long way between stops to Plenty Rd ...

BUNDOORA PARK STATION - #86 TRAM INTERCHANGE
Site potential: C
Possible Location: Plenty Rd
Park and Ride Potential: B
Some larger dispersed commercial and industrial sites along Plenty Rd. The large amount of surrounding parkland makes this a less than ideal point for the actual interchange with the tram, and so we suggest positioning the station to attempt to garner the largest residential catchment for the station.

THOMASTOWN SOUTH STATION
Site potential: B
Possible Location: Cheddar Rd & Hanrahan St
Park and Ride Potential: B
Thomastown is a kind of sprawling, lumbering semi-industrial suburb that was absolutely gutted by the 1990s recession - having been home to enormous swathes of now vanished manufacturing. The area is only really just now starting to re-make itself, and it has enormous potential for re-development of almost unlimited scope, scale or use.

THOMASTOWN STATION - MERNDA JUNCTION
Site potential: B
Park and Ride Potential: B
Surrounded by variously industrial, retail and residential zones, Thomastown Station offers significant potential for the creation of an effective mixed use neighbourhood, and in fact if we were grading the prospects of the activity centres, we think no other such centre presents so high a potential with the addition of orbital rail. As we can see, it's possible to create fully 3 stations (2 new) which are very well located to create a large scale, medium density mixed use suburb. We strongly suggest Thomastown needs to rise up the activity centre priority list accordingly.


THOMASTOWN WEST STATION
Site potential: C
Possible Location: Ring Road and Mahoney's Rd
Park and Ride Potential: B
Although this station would have a large residential catchment, it would also serve the eastern end of the larger industrial sites situated between Mahoney's and the ring road, providing some further redevelopment opportunities across the wider Thomastown activity centre.

CAMPBELLFIELD STATION - UPFIELD JUNCTION
Site potential: B
Possible Location: Camp Rd
Park and Ride Potential: B
Significant planning has already gone in to re-instating the former Campbellfield Station, which closed in 1956. In fact provision was made for the station during the recent level crossing removal, and this is an obvious urgency. It's long been an incredible frustration for users of the orbital smart bus routes that because of this station's absence they don't actually connect conveniently anywhere with the Upfield line. There are significant industrial, commercial and retail sites in the vicinity of the proposed station, including Campbellfield Plaza, such that the potential for developing an effective mixed use neighbourhood around the station is quite high here.

BROADMEADOWS STATION - CRAIGIEBURN JUNCTION
Site potential: A
Park and Ride Potential: A
Broadmeadows is obviously one of the main designated activity/employment centres under Plan Melbourne, around which extensive work on future land use planning and so on is already underway. We will look next week at the possible infrastructure issues around the station, where it is anticipated this would be the point that we finally rise above ground since we first hopped on at Southland, from this point, we need to share some infrastructure with the existing network, so we'll discuss that next week.


Profiling the New Stations

We could break all these down by typologies relatively easily and these would determine what type/how much enabling policy you put around facilitating new uses for each, looking something like the following. If we throw in a few of the western suburbs stations to complete the picture, we're looking at something like the following:

1. Designated Employment Centres
Broadmeadows
Box Hill
Monash/Clayton
Airport
Sunshine
Footscray

2. Existing or Potential New Employment Centres
Thomastown
Campbellfield
Burwood East
Middleborough
Moorabbin
South Oakleigh
Glen Waverley
Northland/Heidelberg West
Sunshine North
Keilor Park

3. Universities
Monash
La Trobe

4. Shopping Centres
Doncaster
Southland
The Glen/Glen Waverley
Airport West
Northland
(THINK about it - you will be able to shop 5 massive malls in 1 day with 1 Myki (or 2050 equivalent))

5. Residential/Commuter
Waverley Nth
Blackburn
Springfield
West Doncaster
Balwyn Nth
Heidelberg Heights
Bundoora Park
Keilor East

So that gives us around 20 "destination" stations, and we contend that this is number is much closer to the optimal number of activity centres than the last version of Plan Melbourne posited, if we are to enable a "20 minute city" in more than rhetoric. We contend that facilitating these new land uses and transportation patterns in to them is a goal so important that it is worth spending $50bn over an extended timeframe to solve. But more on that in part three.

Be sure to tune in next week, and we'll look at the western portion of all this in a lot more detail, as well as consider what a Melbourne rail timetable might look like in 2050, once all of this is up and running.

As usual questions, comments and critique are welcome - we love hearing your feedback!

Why Melbourne Cannot Build Metro Rail 2 until Stage 1 is Complete

Correct call, Cap'n!
Victorian Transport Minister, Jacinta Allan

This week, the Greensparty in Victoria committed themselves to building Melbourne Metro 2, which is really a bit like Caligula committing his horse to the Roman Senate in terms of its impact on reality.

"If we held the balance of power in Victoria, committing to building this would be a key prerequisite for our support", is a very different message altogether, and one that would garner them a hell of a lot more credibility with public transport advocates and the general public alike.

Pretending that you'd ever be in a position to actually build the project yourselves, getting out your crayons and doodling wishful lines on a map (qv the umpteen dozen random and ridiculous tram extensions they took to the previous Victorian election) without any concern whatsoever for cost-benefit analyses, only undermines your credibility as a political party.

We are supposed to have turned a corner in this country in relation to infrastructure spending. We are supposed now, in Australia, to be driven by the imperative of allocating scarce resources to those projects with the highest benefit-cost ratios, and we've created a raft of semi-independent bodies to ensure this.

Now, it must be said that I very strongly feel that the way many of these bodies are making their assessments are still strongly based on methodologies that systemically bias road projects over public transport ones.

For Infrastructure Australia to start out with the assumption that "70% of Doncaster Rail's patronage would be cannibalised from existing public transport services" dooms that project's prospects before you've even got your calculator out, and it is completely fallacious when you look in detail at the evidence. Journey to work data shows that public transport mode share in areas proximate to heavy rail is SIGNIFICANTLY higher than this assumption presumes.

But for a party that currently holds two Victorian lower house seats to have put their plans for building a Metro 2  in the public domain whilst holding a straight face is just insulting to the voting public. Could one journalist not have insisted on their explaining how and in what parallel universe this is ever going to happen?

The Greensplan. Note also they are claiming credit for extensions to Wollert and Wyndham Vale,
both of which have been in PTV's Network Development Plan for YEARS ...


"If we held the balance of power in Victoria, committing to building this would be a key prerequisite for our support", would be a good answer to that question. Without that, we are left with - "well, we are going to quadruple our Statewide vote from current opinion poll data, and from our highest ever recorded level of support in just 3 months' from now, and thereby secure government".

But then you're also left with "and we're going to throw out any notion of deferring to Infrastructure Victoria and return to politicians using these billion dollar projects as political pork barrels." It's inspiring stuff, isn't it?

Transport Minister Jacinta Allan's response to the proposal was entirely the correct one. Even if the project stacks up, it absolutely cannot be built until the Metro One Project is complete. That is scheduled for 2021. 3 years from now.

You cannot undertake a project of this scale without fully three years of planning, systems and engineering prep work. That's exactly how long it has taken to get Metro 1's shovels in the ground after the election of the Andrews Government, so let's forget about implying sophistry on the Minister's behalf, and let's credit her with being the only party to the discussion who appears to be living in the real world.

You can add to that assessment the fact that there are actually a finite number of workers adequately skilled for these sorts of projects available at any given time, and if you try and build such a thing in an environment of scarcity, you wind up significantly driving up labour costs and ballooning the total cost of the project.

But there's another crucial reason why Metro 2 cannot possibly be built before Metro 1 is complete. We need to consider the interaction of the two projects and the overall project goals. In fact there may be a far more cost effective solution for Metro 2 which builds upon the infrastructure already in place for Metro Rail 1. Readers will be unsurprised at this point to learn there exists a patented Wombat Plan for Metro 2 which does precisely that.

Hang On, What IS Metro 2?

Broadly speaking, Melbourne Metro Rail 2 is the proposal to re-route heavy rail services from the western suburbs of Melbourne over the Yarra River from Newport Railway Station, thereby providing the new Fisherman's Bend development zone with much needed heavy rail access.

Most proposals to date have conceived this project as a rail tunnel running through Fisherman's Bend then back under the river to new underground platforms at Southern Cross Station, Flagstaff and CBD North, and continuing through the inner north before returning above ground at a junction with the existing South Morang and Hurstbridge lines.

However, we contend that there is a way of doing this which provides significantly better returns in the all important 'project benefits' column.

What's Wrong With These Proposals?

We start out with the proposition that the extra capacity potentially provided by this proposal at both Southern Cross and Flagstaff (the lowest trafficked city loop station by a significant quantum), is completely redundant to the network's needs.

We also contend that Melbourne has created a significant urban problem in the Southbank residential redevelopment zone. One of the main benefits of this type of living is supposed to be reducing car dependency, but we've seen a lot of data recently suggesting that car use and certainly car ownership in Southbank is actually out of control.

The area is walkable to everything in the CBD, and has trams running along Kingsway, Queensbridge and Sturt Streets, but these tram routes actually really border the main areas of the suburb rather than running right through it. If the logic exists to provide heavy rail access to the Fisherman's Bend redevelopment zone, the same logic should have applied when we were planning Southbank. We believe the heavy rail opportunity now created at Fisherman's Bend provides an opportunity to remedy the lack of planning at Southbank.

Melbourne Metro Rail - Wombat Style

We therefore propose that instead of running via Southern Cross Station, Metro 2 should continue east via 1-2 new stations at Southbank and re-join the remainder of the network at the Metro 1 tunnel, whose capacity it would share through the CBD, before running underground through the northern suburbs and meeting South Morang/Hurstbridge roughly as per existing proposals.

Click the images below to enlarge.


So, we're essentially creating 4 new stations south of the river - Wirraway (which I've situated so it can in fact serve both the Wirraway residential zone and the designated employment zone to its north), Sandridge, Casino/Convention Centre, and Southbank.


In the north, which is really pretty well transport enabled already, it's just two new stations for the shorter tunnel - we see the return from the dead of Museum Station (at which far too many people arrive by car - the location was never sensible from this perspective) and Johnson St, approximately half way between Smith and Brunswick Streets. Alternative name would be "The Rochy" :)


Metro Tunnel Capacity

The obvious benefit of the Wombat proposal over anything running via Southern Cross is the shared tunnel infrastructure with Metro Rail 1. Armchair critics will already be reaching for their revolvers about the limited capacity of that tunnel reintroducing a bottleneck into the network.

I fully concede that would be the greatest weakness here, but I don't think it actually need be a limiting factor once we sit down and actually look at the numbers, given that we are building the Metro 1 tunnel with future high capacity signalling in mind.

Let's look at how this might work. We are suggesting that ONLY Werribee line trains be re-routed through the Wombat Metro Tunnel, and that Williamstown line services would continue to run above ground to Southern Cross and/or Flinders Street, otherwise we're left without any trains at Seddon, Yarraville and Spotswood.

Looking at the 2016 Network Development Plan's projections for 2026 - 20 peak hour services are scheduled to run via Newport. Unfortunately the plan is agnostic as to how many of these originate from Williamstown and how many from Werribee, but let's assume a ratio of approx 3:1 in Werribee's favour, so let's say 14 and 6. It assumes 14 services running via the Metro 1 tunnel by the same date.

PTV Network Development Plan
Peak hour projections for 2031


So the key limiting question here is whether the capacity of the Metro Tunnel would allow for 28 peak hour services within the tunnel under construction. Given the current, prehistoric, steam powered network signalling has an acknowledged capacity of 20 trains per hour, we're looking for a 40% improvement, to allow a train every 2.18 minutes.

Network signal capacity is something of a dark art - as we're already experiencing with the high capacity trials underway, but there is no denying that this demand would be within the acknowledged international capabilities of high capacity signalling systems of up to 36 trains per hour.

At the other end, we then have the option of re-routing either the entire Hurstbridge or South Morang Lines through the tunnel (both would not be an option for capacity reasons and it would again render a whole raft of inner city stations redundant), OR this could be the route of a future Doncaster rail link along the Eastern Freeway.

Looking ahead to 2031, if the Airport rail link DOESN'T utilise Metro 1 tunnel, and instead runs direct to Southern Cross, then we would need to be able to run 33 trains an hour through the tunnel, and we concede that this would be straining the upper limits of today's high capacity signal technology, but you would then have the option of running some Werribee services above ground to Southern Cross to further mitigate.

PTV Network Development Plan
Peak hour projections for 2031


Furthermore, if the capacity constraints were only in a single direction through the CBD, you would actually have the option of running some Werribee services BACKWARDS through the CBD - ie above ground from Newport - South Kensington then into the Metro 1 tunnel and returning to Werribee via Fisherman's bend.

So there you have it. We tender the merits of the Wombat Plan on the basis that it
1. Minimises costs through shared infrastructure
2. Provides heavy rail access to major destinations and public transport blackspots in Southbank
3. Creates future capacity for Doncaster Rail (the peak hour constraints would all be in the opposite direction)

Tallying Years of Failed Planning - from Melbourne's Heavy Rail Dark Age into Renaissance

In the years 1930-2017, while Melbourne's population has grown FOURFOLD, the only major rail track expansion projects performed in the city have been the Alamein extension and City Loop.


I came across this map the other day, and was instantly struck by the fact that the Melbourne metropolitan railway network appeared more extensive in 1930 than it does today.

And it's an interesting case study of how transport priorities shape a city's development.

Settled in the 1830s, and booming by the 1850s, Melbourne's core was established in the pre-automotive era. The only private transportation option for almost all early Melburnians rich or poor was the horse /and cart/carriage, and horses required stabling and intensive daily "maintenance". So unless you were a business owner who needed to transport heavy goods, or were well enough off to afford servants to take on the chores, chances were you relied on public transport and/or foot to make your way around what was an infinitely more compact city than we know today.

By the time the first automobiles began appearing on Melbourne's streets around the turn of the Twentieth Century, the rail network had been central to the city's development for nearly fifty years, and what was in it's day one of the world's most extensive cable tram networks had been steadily replacing the far slower 'omnibus' network of horse-drawn trams since 1885.

By the 1900s, the driving force for new railway lines were the farmers and loggers beyond the city's core suburbs seeking primarily to get their goods into Melbourne. The growth of settlements beyond the city fringe essentially followed the spread of the railways, and there were no "car commuter" towns as we would know them. The only sensible and efficient way to head in to "town" for most was by train.

Melbourne in the 1930s - Another World

By 1930, Melbourne's population was around 1 million, or 22% of its current size. The metropolitan south-east ended around Moorabbin. Circling round anti-clockwise you'd find not much but bush settlements beyond Camberwell, Heidelberg, Preston, Coburg, Broadmeadows, Essendon, Footscray or Williamstown.    

Even by well into the 1930s, petrol-driven cars were mostly expensive luxuries affordable only by the few. In 1922, a population pushing towards one million people owned just under 45,000 motor vehicles, a rate of ownership well under 5%. Prior to the introduction of the Metropolitan Road Code in 1936 there were no speed limits on Melbourne roads, no requirement to keep left, nor park in any particular place (see picture above), so the city's roads in the 1930s were still rather unruly and dangerous places.

So, at the time this map was made, the vast majority Melburnians remained dependent upon the now extensive public transport system to go about their business.

Many planned extensions of the rail network were interrupted by World War Two, after which time planning modes had begun to give primacy to the private motor vehicle, and investment in rail disappeared from the policy agenda.

Following the completion of the Glen Waverley line in 1930, the Ashburton line was extended to Alamein in 1948, but these were the only non-electrification extensions until the City loop opened in 1980. As a measure of how few votes politicians thought there were in public transport, even as recently as the early 1990s, Jeff Kennett seriously entertained a proposal to completely close the Alamein, Williamstown and Upfield lines and replace most lines with buses after 8pm.


Rail in Melbourne - What We Have Lost

Melbourne's historic rail closures are shown below. The yellow lines are those closed since the turn of the century, the purple are nineteenth century closures. The eastern purple is the outer circle line, partially replaced by Alamein. The northern is the Inner Circle.

The white lines are the modern track additions. The Rosstown Railway is shown by the line running St.Kilda-Malvern, now to be basically replicated by the Metro tunnel. The notoriously disastrous freight only service never turned a profit.

The green line is the current day Urban Growth Boundary, the orange line a guesstimate of the suburban boundary around 1930, the shaded area a guesstimate of the populated core without sparser/satellite regions.

Today Kew, is of course well serviced by light rail, and the Port Melbourne and St. Kilda light rail services both have higher patronage than the heavy rail they replaced. Neither the Whittlesea nor Healesville closures were within the current urban growth boundary, and remain reserved for future growth, with the South Morang-Mernda extension announced only recently. So Melbourne has at least been spared the fate of many US cities who are only now replacing the rail services they ripped out fifty years ago. So far, so good.

Our 1930s rail map doesn't necessarily represent the high water mark for coverage of the suburban railway network, nor is it an apples with apples thing to compare to today, when a large number of these services were still provided by steam in 1930, the map includes services to satellite settlements, so a comparable map should perhaps include today's V/Line network, while the Melton service remains unelectirifed, so is that actually an effective comparable loss? It's actually quite hard to present systematically.

By 1930, Doncaster was already the obvious gap, but most everywhere else the city's development can be seen to have essentially followed the heavy rail corridors, and thus a reasonably comprehensive geographic coverage for rail. It does bear remembering that Doncaster remained largely orchards until the 1950s, and of course had already had the experience of Melbourne's first failed tram route through to Box Hill. These fringe satellite towns in the 1930s were essentially still rural in character and contrasted markedly with transport-enabled inner Melbourne.

The following table probably outlines things best - and it's the net km figure by period that maps it most relevantly. I've obviously not tallied the net kms prior to 1920, when most of the track was laid. So it's not a complete picture, but it's a telling snapshot of the last hundred years. I've assumed a 2020 opening date for Melbourne Metro. See the image below for an illustrations of the regions I've used.

And to reiterate this is measuring actual TRACK expansion, not electrifications of existing track.

Using final electrification as a common metric would make sense, but it just becomes an exercise and a half, and wouldn't provide a much more meaningful picture. The network was mostly electrified by the end of the 1930s, however both the Fawkner line to Upfield and the Reservoir line to Lalor had to wait until 1959. The Belgrave line wasn't electrified until 1962, Epping until 1964, Pakenham 1975, Sydenham 2002, and Melton is still waiting.

It does all invite one very stark conclusion. Bar Alamein and the loop, all of the expansion in Melbourne's metropolitan train network since 1930 has occurred as electrification of existing regional track through the city. And if we were to break it up into 20 year blocks, it would essentially show total net stagnation for the past eighty to ninety years. Only Metro rail will tip the ledger back in favour of growth.

From the time it was last extended to Alamein in 1948, Melbourne's heavy rail network has essentially been relying on the same track infrastructure laid mostly one hundred years earlier.

 

 

Marvelous Metastasising Modern Melbourne

But as we've seen, the primary mode of rail network expansion in Melbourne has been via electrification, and this HAS enabled Melbourne to grow radially while providing heavy rail access to most new regions, albeit only in sites where the rail network already extended beyond the suburban fringe. The yawning transport black hole beyond the end of the Glen Waverley line looms as one of the city's most obvious historical planning failures.

So, as we've moved from the orange to the green below, the proportional geographic coverage of rail has declined. As the motor car removed the imperative to only create new housing within a finite distance of a rail station, so the sprawling hinterlands away from heavy rail that would have previously been undevelopable soon saw housing estates rising on them as the fifties moved into the sixties.

The arrival of television in 1957 compounded the extent of these external changes a still relatively young Melbourne was facing. Theatres closed all across town. A city which in 1956 saw enough demand from night owls and shift workers to run a twenty four hour tram network, had closed it by the end of 1957. Melbourne's CBD lost its primacy as a shared recreational or shopping destination for the entire city as car-parking enabled suburban malls took over. It took the CBD over thirty years for it to regain something of its former role.

The "green wedges" policy did to some extent force development towards the radial "spokes" of Melbourne's heavy rail network, but because the spokes are necessarily further apart the further one travels from the CBD, and where housing densities in these locations were significantly lower than historic inner Melbourne, huge blackspots emerged particularly in the outer east for anyone not within walking distance of a station.

And with a consequent decentralisation of employment centers - even heavy industrial areas actually have a very low employment density so are difficult to adequately provide public transport to, and frankly with a suburban bus network that has ALWAYS been third world, and which neither properly supports nor adequately integrates with heavy rail, we know what the outcome has been -

public transport in Melbourne now has around a 11% mode share, where in the 1930s this would have been somewhere like 85%, and our roads are permanently clogged with commuters instead of the commercial vehicles they are actually necessary for.


What's worse is the current mode share is only a recovery back to 1975 levels. Public transport mode share continued to plummet all the way to the 1990s. In 1997 it bottomed out at 7.7%, almost half the figure for Sydney, where today that gap is only around 3%. So something about this was a very Melbourne phenomenon. And wombat readers will detect a soapbox when I go on to suggest the less radial nature of Sydney's network, combined with its geography was a key reason why it was better able to cope with the "sprawl" era of planning.

But I don't suggest that era actually covers more than about forty years, around 1955-95. I would in fact suggest Melbourne hasn't planned for any major new housing developments in rail blackspots since about the mid-eighties, and some degree of policy lag is to be expected.

 

 

Calculating the Failure

The following map illustrates the current state of Melbourne's "preparedness" to cope with the next phase of its development.

The blue lines are current the heavy rail network with Metro rail. The pink are currently operating V/Line routes. The red are closed routes where the track remains reserved for future development.


Interestingly, the shaded core 1930s component when mapped with today's metropolitan tram system shows you pretty neatly around when we stopped investing in that network. Of course it's to the city's eternal credit that network was retained, minus the radial lines into Footscray, but it has, along with the already noted "spoke effect" of widening a radial rail network, created (or, some might argue merely enhanced) a great disparity in transport options between Melbourne's inner and outer suburbs.

But at a closer look, public transport black spots were already appearing around rapidly growing communities in the south and north east by the 1930s.


The other point worth making is that NONE of the track extensions even as far ahead as a vaguely proposed Metro Two tunnel have added a centimeter of track outside Melbourne's 1930 boundary. We haven't built a single skerrick of extra track for ANY of the multitudes living in the multitude of new suburbs we've built during that time.

However, the rail reservations created in the city's west, particularly those now created by Regional Rail Link ensure that we are unlikely to commit the more egregious mistakes of the past fifty odd years over the next.

The issue for discussion, as far as this commentator is concerned, is how far we can go in undoing the mistakes of the east, particularly as we acknowledge an urgent need to develop suburban CADs in those locations and build a future airport rail.
