To the surprise of many, the state government yesterday announced a major $2 billion upgrade of the Dandenong/Pakenham/Cranbourne lines — they’re saying it’ll be enough to boost capacity by about 30%.
The government’s press release is here, or you can watch a video:
25 new high-capacity “next-generation” trains. They’ve been talking about this for years. The newest trains on the Melbourne are basically a 10 year-old design with some tweaks. If the talk has been correct, this new batch will have more doors (to cut dwell times at stations), fewer seats, walk-through passenger areas, no middle cabs (pointless as almost all services now run as full 6-car sets) and lots of handholds. Probably a tad longer (perhaps even a 7th carriage) — overall carrying about 20% more passengers per train.
In other words, they’ll be similar to the sorts of high-capacity trains you see in other big cities around the world. Of course squeezing more people in needs to be balanced out with enough seats so that people travelling long distances don’t have to stand all the way. (See also: How many seats do we want on our trains?)
Grade separation of four crossings. They’ll hit the worst of the remaining ones: Clayton Road (where the level crossing often causes long delays to buses and ambulances), Centre Road (so close to Clayton Road you’d pretty much have to do it at the same time), Murrumbeena Road (infamous for long delays to road users) and Koornang Road. In the process there’ll be new stations at Carnegie, Murrumbeena and Clayton.
Early works on more. Planning and early works funding for the grade separation of Grange Road (Carnegie), Poath Road (Hughesdale), Corrigan Road, Heatherton Road and Chandler Road (Noble Park). When these are eventually done, and given the Springvale grade separation is currently underway, the entire stretch from Caulfield to Dandenong will have no level crossings, making it possible to run a lot more trains, without causing a ruckus by blocking up road traffic — as in fact happened yesterday when following a disruption, some motorists waited up to an hour.
High-capacity signalling. As I explained a few weeks ago, “moving block” signalling makes it possible to run a lot more trains along a line. Presumably this will include at least the busiest section, from the City Loop to Dandenong, but it may also include the full lines, out to Pakenham and Cranbourne. It will also need all trains running on the line to be fitted with in-cab equipment, including V/Line trains.
Maintenance depot at East Pakenham. At a guess, this is where the new trains will be serviced, and I’d hope some extra track for this facility will also allow Pakenham suburban trains to shunt out of the way of V/Line trains.
Power upgrades to make sure there’s enough juice for all these new trains.
It appears the package is fully funded, not an election promise. It’s not clear where the money came from, but according to the government it is actually funded: The $2.5 billion for the Cranbourne-Pakenham project will be included in the Budget and is “all new money”, Dr Napthine said.
The project is scheduled to start in 2015, with completion in 2019.
What’s not included
Duplication of the Cranbourne line. I’m very surprised not to see this listed, though the rumour is that works will address at least some of it. I hope so, because the cost of it would be tiny in comparison to the rest of the package, and having a single section of track will hamper efforts to get the most capacity out of the project.
Third or fourth track to Dandenong. With little CBD stabling capacity, you wouldn’t go to the expense of a third track unless you are also building a fourth. This package doesn’t appear to include this, though it’s said to be in the longer term plan for the line, particularly if the Port of Hastings is eventually developed. Hopefully the grade separations and new stations are being built with this in mind.
Metro rail tunnel. This is commonly seen as a solution to rail capacity at the CBD end, but actually it doesn’t matter that much yet. Two tracks from Dandenong into the City Loop means that, provided no other trains share that loop tunnel, capacity shouldn’t be an issue. This could, of course, mean bye-bye to Frankston loop services.
Enough new trains for the whole line. If you have peak services every, say, 3-4 minutes, and a round trip of about 140 minutes, you’d need about 40 trains, plus a small number of spares. Obviously there’s scope to expand the order later, but for consistent loads and running times to maximise line capacity, ideally you’d want every train to be the higher capacity model.
In practice they might decide they’ll target them at the “peak of the peak” hour, or on the busiest of the two lines, until they eventually have enough bigger trains.
Connecting buses. No doubt they’ll benefit from the removal of level crossings, but there’s no word on service upgrades. Getting the trunk route to the south-east working well is great, but its potential is so much greater if there is a network of frequent connecting services for the benefit of people travelling to or from locations beyond walking distance of stations — at present many connecting buses are hopelessly infrequent. Smartbus routes are a good model here, and can be provided on more routes and services boosted, particularly on weekends.
It’s also unclear if quirks in the train timetables will be fixed: late Sunday starts, infrequent services early on weekends, 30 minute waits after 7pm on weekends (and after 10pm on weekdays). Hopefully these will be included in the service upgrades to accompany the infrastructure and fleet improvements.
Overall it’s a great upgrade. It will bring the Dandenong line into the 21st century, with modern trains and signalling, providing a big boost to capacity… it will bring the operation of the line much closer to world’s best practice.
There’s one glaring exception: the remaining single track on the Cranbourne line. Surely if you’re throwing a couple of billion dollars into the line, you’d have to fix this. Hopefully that is the case.
V/Line passengers may be unhappy that they’ll still sit behind suburban trains for the metropolitan portion of their trip. That’s an annoyance, but they alone aren’t reason enough for extra tracks… V/Line’s figures indicate for the entire morning peak, the 5 trains arriving in Melbourne between 6:59am and 9:28am carry 856 passengers — about one suburban train load. Certainly something needs to be done to improve travel times for regional passengers (and attract more of them off the road), but the immediate concern is suburban capacity. And the new signalling and measures to reduce suburban train dwell time delays will help.
It does make sense to target one line with a package of upgrades to ensure its performance will be humming as demand continues to grow. But it begs the question of when other lines and other public transport users around Melbourne will benefit from this kind of modernisation.
- Marcus Wong makes some great points about the unusual way this proposal has come to fruition: Dandenong line upgrade and probity concerns
- PTUA: Big win for south east, no win for west and north, masks ‘split personality’ on transport policy
- The $100 million Bayside (Frankston/Williamstown/Werribee) package
- In the west, the Regional Rail Link is underway, and will help the Williamstown, Werribee and Sunbury lines
- Also yesterday: PTV released a timetable API — a what? It means geeks who write apps can now look up official public transport timetable information
- …and the state government announced their scheme for concession fares for international students — basically yearly tickets only, and they haven’t yet published the pricing
Note: The Coalition’s plan for the Dandenong line has been superseded by the Labor government’s plan, released in late March 2015
