Questions about the decision to build the tunnels for the North West Rail Link (NWRL) too narrow and too steep for existing Cityrail rolling stock have resurfaced as the government signs the tunnel boring contract for them. Transport Minister Gladys Berejiklian had already admitted that any savings from narrower tunnels on the NWRL would be outweighed by the costs of retrofitting the existing Epping to Chatswood Line, but it now appears likely that one of the bidders for this contract had offered to bore the tunnels at the larger diametre for the same price.

Rumours of this have been circulating, and were first raised in this blog last month on 29 May in the comments section:

“I heard that one company that tendered offered to bore the tunnels to the regular specification for double deckers at no extra charge to facilitate future integration and they were told to go away.” – Joni (29 May 2013)

It was then put to Ms Berejiklian during question time last week. She was asked whether she had received such advice, a question which she dodged in her response. Her refusal to deny it strongly suggests that she has received such advice. The response did, however, contain one of the best interjections made during questions time, by Labor MP Richard Amery:

Mr MICHAEL DALEY: My question is directed to the Minister for Transport. Given the budget appears to confirm that the North West Rail Link will be nothing more than a privatised shuttle service, has the Minister received any advice that the tunnels for the North West Rail Link could be bored to a width that would accommodate double-deck trains at no additional cost to the project?

Ms GLADYS BEREJIKLIAN: Members of the New South Wales Labor Party should hang their heads in shame in relation to the North West Rail Link.

Mr Richard Amery: We’ll have to, to get through the tunnel.

The logical conclusion from this is that the government’s decision to proceed with narrower tunnels is not due to financial considerations. Instead, it is to guarantee that the NWRL remains a segregated, privately operated system that does not interact with the existing Cityrail network.

This is the dominant vision of the transport planners at Transport for NSW, and has been ever since 2008 when they convinced the state government to build a completely segregated metro line from the CBD to Rouse Hill (since abandoned and replaced with a cheaper option that also uses portions of the existing network rather than building completely from scratch). This would prevent the new line from being operated by Railcorp, an organisation that is seen by these planners as slow, inefficient, expensive, and lacking a user (i.e. passengers) focus. Ms Berejiklian often cites that it costs $10m per day to operate, about the same as the London Underground but with about a quarter of the patronage. She is therefore leading a structural reform of Railcorp, with the creation of Sydney Trains and NSW TrainLink, but simultaneously also pursuing the option of a completely new line operated by “anyone but Railcorp”.

The decision to make the tunnels narrower and steeper guarantees the independence of this new line, ensuring that the private operator can be held entirely accountable without being able to blame the government rail operator (e.g. because a delay on Sydney Trains prevented the private operator from running on time), while also neutering union opposition to advancements like driverless trains. It is the poison pill that prevents any future government from having a change of heart and integrating the NWRL into the rest of the Cityrail network. Their fear is that a future government could do this in order to, for example, once again scrap the construction of a Second Harbour Rail Crossing, a project announced and subsequently abandoned so many times that transport planners may have found a way of ensuring it gets built – by holding another line hostage in the process.

Nor would wider tunnels necessarily be some silver bullet, the tunnels would still be too steep for existing rolling stock. And it’s worth remembering that any future tunnels under the Harbour (the government is planning its Harbour Rail Crossing to be an under the Harbour tunnel) may also have to be quite steep and the existing tunnels between Epping and Chatswood are already too steep for some existing rolling stock, resulting in new rolling stock like the Waratah trains being built to be compatible with the steeper gradient. Similarly, there are few technical barriers to prevent future double deck rolling stock designed to navigate the narrower and steeper tunnels on the NWRL. But it will prevent that from happening long enough to see whether private operation of heavy rail results in better outcomes, and should be expanded; or is a repeat failure like the privately owned Airport Line, and should not be repeated.

Correction: It’s been pointed out that Tangaras, although not initially used in the Epping to Chatswood tunnels due to their steepness, now are used in them. This is confirmed by the proposed October 2013 timetable. In other words, rolling stock that was not initially able to be used on the Epping to Chatswood tunnels were later able to be used in those tunnels. This is consistent with restrictions on existing rolling stock on the NWRL tunnels, where future changes could also allow double deck trains to still be used on them.

Video: WestConnex: Greiner’s folly, Part 2: South-west: the problem & the solutions, EcoTransit

This post was inspired by the recent EcoTransit video posted above. In it, the claim is made that 90% of trips into the CBD from the South West are by public transport, while 90% of trips to South Sydney and the UNSW/Prince of Wales Hospital area are by car. No source was provided for these figures, although a 2008 government report entitled Employment and Commuting in Sydney’s Centres, 1996 – 2006 does provide data for Sydney as a whole and is the basis of this post.

Notes: Car journeys include both drivers and passengers. The majority of the balance of journeys were made by public transport, with walking and cycling generally not exceeding 5%-10%. All figures refer to journeys to work only and come from 2006 census data.

The data splits Sydney up into:

  • 33 major “centres” (714,496 jobs or 37.1% of Sydney’s total)
  • “no fixed address” (78,077 jobs or 4.1% of Sydney’s total)
  • “unknown” (110,342 jobs or 5.7% of Sydney’s total)
  • “remainder” (1,020,985 jobs or 53.1% of Sydney’s total)

As a general rule of thumb, the centres tend to have both a higher employment density plus a lower share of journeys to work made by car, and these two are negatively correlated (i.e. if one is higher, the other tends to be lower). At the top of the list is the Sydney CBD, with an employment density of 546.4 jobs/Ha and share of journeys by car of 19.5%. This compares to the figures for the non-centre areas of Sydney (“remainder”), with an employment density of 0.8 jobs/Ha and share of journeys by car of 85.2%.

There are some shortcomings of these data:

  • They are relatively old (7 years). This means, for example, they pre-date the 2009 opening of the Epping to Chatswood Rail Link.
  • They only include journeys to work (as this is the question asked on the census). Journeys to schools, universities, TAFE, etc are not included, even though they tend to occur at similar times as the morning commute, nor are journeys for recreation, shopping, etc.
  • They don’t indicate what level of parking restrictions (for both on and off-street parking) have been put in place. Limiting the amount of available parking (particularly free and abundant parking) leads to a significant decrease in driving to work. The case of limited parking vs increased employment densities is a bit of a chicken and egg argument over which causes the other. It’s assumed here that they go hand in hand, and therefore employment density can be used as a proxy for parking limits.
  • They don’t show which specific mode of transport was used (e.g. driver vs passenger or train vs bus vs walk). These figures are available in the original source document, but have been aggregated for simplicity.

Looking at the data in a more visual form, patterns become quickly evident. Here the mode share of trips by car is shown on the y-axis, the employment density is on the x-axis, and the size of each bubble indicates the size of each centre by employment. Bubbles are colour coded by centre type the same way as in the table above.

The link between employment density and driving to work is quite clear – the higher the employment density, the less likely workers are to drive to work. The correlation is strongest up to an employment density of around 150. Above this, higher employment densities do not seen to result in lower car usage, with the Sydney CBD (the large blue bubble on the far right), being a bit of an outlier. However, that is based on a fairly small sample size of 4 centres, whereas there are 29 centres under the 150 jobs/Ha threshold.

Proximity to the Sydney CBD also seems to result in lower car mode shares, evident by the non-CBD Sydney Central centres and the City Education/Health Precinct (the 3 blue and one green bubble on the bottom left) all having a lower car mode share than other centres with similar employment densities. Removing these 4 centres gives a much cleaner correlation, where going above the 150 jobs/Ha threshold still reduces car mode share, but at a lower rate.

Education precincts also have lower car mode shares. The City and Randwick Education/Health Precincts (the two green bubbles in the bottom left) both have lower car mode shares than other centres with similar employment densities. This is more pronounced for the former, given its proximity to the CBD, but can still be clearly seen for the latter.

Business parks, on the other hand, tend to have higher car mode shares. Norwest Business Park and Macquarie Park (the 2 red bubbles at the top), both have much higher car mode shares than other centres with similar employment densities. Olympic Park and Rhodes also have higher car mode shares than similar centres. This may suggest that it is their lack of good rail connections that encourage their workers to drive. The former 2 had no rail connections in 2006, while the latter 2 had only limited rail connections.

But support for this in the data is mixed, given that North Sydney and Chatswood (the two red bubbles on the right) both enjoy excellent rail connections, but still display a greater tendency for its workers to drive. In the case of North Sydney (the red bubble on the right), it has a much higher employment density than Surry Hills/Kings Cross (the lowest blue bubble on the left) does (369 jobs/Ha and 137 jobs/Ha respectively). Yet both have similar car mode shares (39.4% and 37.9% respectively) and are both in close proximity to the CBD. In addition, the Randwick Education/Health Precinct (the green bubble second from the bottom) has no rail connection and achieves a similar car mode share to St Leonards/Crows Nest (the red bubble third from the right) which does have a rail connection. This is despite the former having a lower employment density to the latter (70 jobs/Ha and 107 jobs/Ha respectively).

This suggests that the type of public transport available does not impact its mode share significantly. Instead, it’s the quality of that transport, things like speed and frequency, that determine its use. So somewhere like Rhodes, which has relatively infrequent and slow trains on the Northern Line, is not as well services as the Randwick Education/Health Precinct, with its frequent express buses that come in from Central and the CBD via bus only lanes.

Summary

Higher employment densities are correlated with lower car use in journeys to work, particularly for densities up to 150 jobs/Ha. Proximity of employment to the CBD enhances this correlation. Meanwhile, workers at universities are less likely to drive, while workers at business parks are more likely to drive. The availability of frequent and fast public transport encourages a modal shift to public transport, the mere existence of a rail connection does not.

Further Reading

Paul Mees’ 2010 book Transport for Suburbia discusses the issue of population density and whether a high population density is required to achieve high public transport usage. He argues that it is not, and that a low density city can still achieve high public transport usage.

Post Script: Paul Mees sadly passed away earlier this week on Wednesday, before this post was published, but after the above paragraph was written. He was a public transport advocate, heading the Melbourne based Public Transport Users Association for a decade, as well as an academic at both Melbourne University and RMIT.

Chris Loader at Charting Transport looked into this further for cities from various countries, then in more detail on Australian cities, and finally into great detail on just Sydney. Two maps looking at employment density and public transport use in Sydney most relevant to this from the final link are included below.

An earlier post on the WestConnex looked at whether it should link up to the CBD, and what sort of trips car travel is best suited to compared to what sort of trips public transport is best suited to.

A quick follow-up to yesterday’s post about integrated fares, looking at both case for and the case against rolling out integrated fares at the same time as integrated ticketing (Opal).

Sydney might be ready for integrated ticketing, but is it ready for integrated fares? (Source: Beau Giles)

Sydney might be ready for integrated ticketing, but is it ready for integrated fares? (Source: Beau Giles)

First, the case for, by developer Stephen Mok, who argues that a trial is not a true trial if it does not also test the removal of intermodal transfer penalties.

“There’s two reasons why I’m concerned right now:

1) I’m surprised that intermodal transfers are not part of the trial. I would’ve thought that IS part of making sure the technology works – surely the integration between transfers with timing, default fares, etc needs to be tested too? And if it’s going to be tested, I would’ve guessed ferry/train would be an easier starting point, before buses are involved.

2) The communications seems to be quite different this time, compared to the start of the ferry-only trial. There’s a lot less of the “more details coming” talk. The “you only pay when you catch a train or bus or ferry” and “there are only single fares on Opal” don’t technically rule out free intermodal transfers, but also doesn’t sound open-ended. The lists of the benefits of Opal (daily cap, travel reward calculation, etc) sounds final, rather than a list that will be extended. Today’s comments from Gladys defending the pricing itself under Opal (vs existing periodicals) reinforced that too – making it sound like there really will be no MyMulti replacement in any form!” – Stephen Mok

And the case against, by engineer Perry Stephenson, who argues that adding complexities early on increases the chance of failure from both an engineering and political perspective.

“If you’re a clever engineer, looking at the roll-out like a clever engineer would and identifying the risk that by attempting to integrate fares as well as roll out a swipe-card system simultaneously, you’re likely to hit some fairly complex problems along the way and likely end up failing like the T-Card did.

Instead, if you focus on the technical issues surrounding a swipe-card roll-out, complete the roll-out quickly and within budget and get 12 months of operations for troubleshooting post-launch, you’re in a much better place to focus entirely on the integration of fares using your new, stable, real-world tested ticketing platform. Also you’ll have 12 months of adoption by the public and hopefully high numbers of users.

I know it can often by politically difficult to try and explain engineering considerations to the public (especially when they start trying to use that logic against you in letters to the editor) but I’d suggest this is the real reason they aren’t doing both at once.” – Perry Stephenson

In other news, Charting Transport has a new post up about multimodal trips in different Australian cities, which is quite relevant to this topic. A must for anyone who loves lots of graphs!

Sydney still lacks true integrated fares. In Melbourne, a single ticket allows you 2 hours of unlimited travel within a certain zone. You then decide how to get from your origin to your destination, what sort of vehicle or combination of vehicles. In Sydney, passengers are generally penalised financially if they transfer from one vehicle to another (unless it is from a train to another train). Someone travelling from Enmore to Circular Quay would be better off changing at Newtown for a train (as would the network as a whole as it would allow the removal of buses from the CBD), but doing so requires paying for an additional train ticket or upgrading to a more expensive myMulti ticket and so virtually all stay on the bus the whole way.

One possible solution, possible now that the Opal smartcard is being rolled out, is to charge passengers based on the total distance of their journey (point to point fares). It wouldn’t matter which, how many, or what combination of vehicles was used, the fare would remain the same. Alternatively, the existing zonal system used for myMulti tickets could be retained (zonal fares), but set at the same price for single or multimodal journeys. To do so for either the point to point or zonal methods means changing the relative fares of single mode and multimodal tickets. This is a relative change, so it could be an increase in the former, a decrease in the latter, or a combination of both. Further cuts in fares is difficult, due to a falling farebox recovery ratio (explained below using the example of Cityrail).

IPART sets fares so that farebox recovery (what passengers contribute in fares) is roughly 28% of Cityrail’s efficient operating cost, but none of the capital cost. So things like the North West Rail Link, South West Rail Link, and new Waratah trains are paid for entirely by the government, but things like staff salaries or electricity to run the trains are partly paid for by ticket sales and a government subsidy. The efficient costs refers to the total operating costs less any non-fare revenue (government concessions, rental income, etc) received.

This 28% target has not been met in recent years. It was 27% in 2008/09, falling to 25% in 20011/12 (Source: Review of maximum fares for CityRail services from January 2013, IPART Nov 2012, page 13).

There were a number of reasons for the drop. The introduction of myZone in 2010 saw a number of fares cut, but almost none increased. No fare increased was made for 2011, though the following year’s increase was a double up to make up for that. The current government has promised no fare increases above CPI without any improvements in services, and has stuck to the CPI limit since 2011. Also in 2011, an additional discount of 9% was provided on periodicals (monthly/quarterly/yearly tickets).

More recently, the government effectively increased fares for ferries by removing them all from Zone 1 and some from Zone 2 in the myZone system, forcing myMulti users up to a myMulti2 or myMulti3 if they wanted a multimodal ticket. The current Opal fare system also does not include periodicals, which if retained could increase fares for some by hundreds of dollars a year. However, most fares will remain cheaper under Opal than under the the current magnetic stripe tickets, particularly for off peak users.

So if cutting fares further is difficult, assuming a limited transport budget that is not increased, then the government would have to increase fares in order to achieve integrated fares. Recent reports suggest that this is not the government’s priority, and that there remains a preference for charging different fares for different modes due to the varying cost structures of different modes. Some minor improvements have been made – such as integrated fares for a single mode (e.g. ferry to ferry, or train to train while temporarily exiting the station), or the daily $15 cap and weekly free travel after the first 8 trips.

This might be enough for now, but will create problems come 2019 and 2020 when the North West Rail Link and South East Light Rail Line are opened. These two projects will in part rely on feeder buses and passengers transferring to second mode of transport in order to reach their final destination. This integrated network approach is a more efficient one, allowing a higher capacity of passenger movements along a central spine using rail based transport. But it needs integrated fares to be truly successful.

The danger remains that Sydney will get integrated ticketing and an integrated network, but no integrated fares.

The North West Rail Link (NWRL) as currently planned, will require many passengers to get out and change trains at Chatswood. Based on government estimates, two thirds of passengers from The Hills in Sydney’s North West would have to do this in order to reach their final destination on the Lower North Shore or CBD. This would continue until a Second Harbour Rail Crossing is built, something which currently lacks a start date, end date, or funding.

The Northwest Rail Link will include a new railway from Epping to Rouse Hill, plus a retrofitted Epping to Chatswood Line. Click on image for higher resolution. (Source: NWRL EIS - Introduction, page 1-3.)

One alternative would be to build additional capacity through the CBD first, and then extend that capacity into the outer suburbs second. In other words, build the Second Harbour Rail Crossing now, and the NWRL and South West Rail Links some time next decade. From a purely engineering perspective, this makes perfect sense – there’s no point in building new lines in the outer suburbs, if all they are going to do is dump passengers in the inner city once they reach a bottleneck.

Melbourne is doing exactly this. It’s current proposal is the Melbourne Metro, a new underground line through the CBD. And it is building this despite calls to build lines to places like the airport or to Doncaster (the latter has similar transport challenges to Sydney’s North West). Not only that, but this has put the Melbourne Metro at the top of Infrastructure Australia’s priority list, resulting in the Federal Government committing $3bn in funding to its overall $9bn cost.

A strong case can be made that the Victorian Government has got the policy right, while the NSW Government has not. But what could be argued is that the NSW Government has got the politics right. This is for a number of reasons.

Building a Second Harbour Rail Crossing will not guarantee that the NWRL will be built, but building the NWRL will force a future government to build a Second Harbour Rail Crossing. In a world where political realities make long term planning a dream rather than a reality, and where transport projects are announced, cancelled, changed, re-announced, and then cancelled again, this is not necessarily a bad thing.

The narrower and steeper tunnels, which force the new line into being run completely independently from the rest of the network, will also allow the government to trial new methods of service delivery, such as franchising or driverless operations on trains. The former has allowed for Sydneys bus network to see improvements to services, lower fares paid by passengers, and reductions in operating subsidy paid by the government to provide them. The latter would reduce the marginal cost of each train service, allowing the government to increase services without as large an increase in operating costs. Neither of these could work effectively if the NWRL was integrated into the rest of the network.

Vancouver Sky Train

These sorts of changes are possible on an existing line, and the Eastern Suburbs & Illawarra Line has often been touted due to it operating virtually independently from the rest of the network. But it is much harder to convert an existing line compared to a new one. Unions are likely to resist change, and existing passengers may have fears of the unknown. Both of these fears would be eased by seeing such changes in operation first, and if they work then they can be rolled out to the rest of the network.

Of course, for those who consider a Second Harbour Rail Crossing an expensive and unecessary expense, then there is little reason to support what the government is doing. The same goes for those who oppose one man or driverless operation. For everyone else, while this may not be smart policy, it certainly looks like smart politics.

I had the chance to see Vivid on Saturday night. I found it interesting, but it was far too crowded for my liking. Still, it’s great to see cultural events in Sydney that bring so many people in. Such events are what make Sydney such a vibrant place to live in and what makes so many people want to come here.

The problem caused by large numbers is the transport problems that it creates. It was pretty bad on Saturday night when I went – George St was closed Northbound past Wynyard and we had to get out of our bus early and walk the rest of the way. But it was even worse the following night on Sunday.

The rail system was overwhelmed, with weekend timetables being run despite the huge numbers of extra people:

Video: byupyu

But crowds had an impact even before the final weekend. It affected me almost 2 weeks ago when I was trying to catch a bus home from Fox Studios, as numerous buses went by full without picking anyone up. It reached the point where some people waiting at the bus stop gave up and walked off before a bus let us on.

It soon became clear that Vivid was causing peak hour like crowds in the CBD, but without peak hour capacity.

This is not the only time when big crowds converge into the CBD and then try to get home, it happens twice a day in the morning and evening peak hours as well as during the New Year’s celebrations, but generally handled well in each of those cases. Given the quantity of people, public transport is the best way to move them. But in this case, there doesn’t seem to be enough capacity to keep up with demand (as well as other occasions – the Christmas party season comes to mind, particularly given the alcohol consumption that forces people into either public transport or a taxi in most cases).

Demand for public transport is a good thing, but only if it is met with sufficient supply. This was the problem faced in Melbourne a decade ago, and this is how the PTUA, their public transport advocacy group, was instrumental in fixing the problem of insufficient public transport. Hopefully we can achieve something similar here in Sydney for major events like Vivid.

Update (7:59PM, 10 June 2013) – There were some additional bus and ferry services timetabled for Friday and Saturday nights, though no additional trains nor anything for the Sunday of this long weekend that just passed. Roads Minister Duncan Gay has reportedly told 2UE that  “We’ve now got effective New Year’s Eve [crowds] and frankly we need to treat it that way”.

NSW Transport Minister Gladys Berejiklian confirmed earlier today that the North West Rail Link will have driverless trains. The new line will be run independently from the rest of the network by a private operator, featuring screen doors and completely automated rolling stock.

Driverless trains are a massive game changer, and have many potential benefits. The most significant is the reduced marginal cost of operating an additional train service. It’s the marginal costs that matter, because it indicates the cost of providing an additional train or savings from cutting one. With lower marginal costs, a much lower level of patronage is needed to maintain a reasonable level of cost recovery via fares. Anecdotal evidence from Vancouver’s Sky Train driverless network (where you never have to wait more than 8 minutes for the next train, even late at night) shows that driverless trains there resulted in marginal cost of $11 per hour.

But there a also reliability and safety benefits. An automated train never calls in sick, or turns up to work late. Meanwhile, human error was responsible for both the Waterfall and Glenbrook disasters, both of which resulted in fatalities.

The transport union has decided to oppose this move, which is unfortunate. Their suggestions that driverless trains will be less safe flies in the face of the Waterfall and Glenbrook examples previously mentioned. It also overlooks the fact that modern aircraft run on autopilot all the time, despite being massive flying machines, where there are many more chances for something to go wrong than a train on a fixed guideway. They probably also fear job losses, but the benefit of driverless trains means that limited resources can be better allocated, to have more station staff or more staff roving trains (something which neither drivers nor guards on trains currently do).

Other concerns have been raised. Advocacy group Action for Public Transport raises the issue of assisting passengers on a train that breaks down between stations on the NWRL, which can be up to 6km apart.

Shadow Transport Minister Penny Sharpe suggests that this represents a broken promise, given that the government had previously said it had no plans to introduce driverless trains. That criticism boils down to how much you consider weasel words to be a broken promise.

Ultimately the decision to go with driverless trains is a good one. It will benefit passengers, and has been proven to work well in many other cities around the world.

The evening peak is very similar to the morning peak. Frequencies are slightly lower, as patronage is more spread out in the evening than it is in the morning. However, this also means there is more scope to increase frequencies in the evening, whereas in the morning there are some lines which are already at the maximum 20 trains per hour limit.

As with the morning peak, the main winners are stations further out (particularly those further out from Hurstville, Gordon, and Revesby), while services are now more harmonised, simpler and more evenly spread out. More services follow clockface stopping patterns, with a particular stopping pattern generally occurring once every 15 minutes. Extra services have also been added, increasing the number of trains passing through Central in the busiest hour of the evening peak from 96 to 109. This is a much larger increase than in the morning, where the equivalent figures are 109 to 117 (or 118 if you count the two 4 carriage trains as two trains, rather than the equivalent of a single 8 carriage train). This should significantly reduce overcrowding issues.

Some stations lose out from fewer services (though generally those remaining services will have extra available seats), and a very minor few will see longer journeys, but these are kept to a minimum. Standouts here are Kograh, Rockdale, Beverly Hills, and Kingsgrove.

Overcrowding

A net 13 additional services have been added during the busiest hour of the evening peak. This includes an extra 15 services: 5 on the Eastern Suburbs Line, 2 on the Illawarra Line, 1 on the Airport & East Hills Line, 2 on the Bankstown Line, 2 on the South Line, 2 on the North Shore Line, and 1 on the Western Line, while 2 services have been removed: 1 from the South Coast Line and 1 on the Inner West Line. As a result, 3 of the 4 busiest lines will see their average load drop under 100%. This means that, assuming passengers loads are evenly spread between and within trains, every passenger will be able to sit down in these cases where loadings are under 100%.

The one line that remains over 100% is the Western Line, which has no spare capacity to increase services any more than is currently the case. Additional demand here must be satisfied from passengers going to other lines or taking the train at times other than peak hour.

2013-06-05 PM Overcrowding Oct 2013

More harmonised stopping patterns on many lines should also result in a more even spread of crowds between trains, which should reduce the spiking of loads on some trains.

This is important, as overcrowding is one cause of delays and disruptions that have so negatively affected Cityrail in recent months. So this will be an interesting measure to look at once the new timetable is introduced in October.

How to read the tables below

  • The PM peak is (roughly) all trains that depart from Central Station between 5:00PM and 6:00PM each weekday evening. This has sometimes been shifted forward or back if the busiest period for that particular line is slightly different.
  • The 2 exceptions to the above are Macquarie Park bound services from the CBD and Parramatta bound services between Blacktown and Harris Park. In these cases, it’s trains departing from Macquarie Park and Parramatta Stations between 5:00PM and 6:00PM.
  • Frequency refers to the number of trains that stop at that station during that hour. It indicates the total capacity of the line, in terms of seats and standing room.
  • Headways refers to the time between trains at Central Station (and not the time between them when they arrive at their destination station). The important figure is the maximum headways, as it shows how long the wait is to the next train can be if you just missed the train.
  • Journey time indicates whether journeys are longer, shorter, or the same, and by how long. This can sometimes be subjective, so use it as a rough guide.
  • Green means better (e.g. shorter journey times, higher frequency, shorter max headways), yellow means unchanged, red means worse.

Airport & East Hills Line

2013-06-04 Draft SWTT 2013 East Hills PM

An extra express service is added during the evening peak hour, raising the total number from 11 to 12. This allows for 3 different stopping patterns, each with 4 trains per hour at 15 minute intervals, down from a far more complex 7 stopping patterns that currently exist. More trains run express, skipping stations East of Revesby, resulting in significantly shorter journeys for outer suburban stations but fewer services for stations such as Kingsgrove and Beverly Hills, which lose their express services.

Bankstown Line

2013-06-04 Draft SWTT 2013 Bankstown PM

An extra 2 services are being added during the evening peak hour, raising the total number from 6 to 8. Many outer suburban stations will see significantly shorter travel times, particularly to Cabramatta, Warwick Farm, and Liverpool. In particular, Bankstown Line trains will arrive at Liverpool only 5 minutes after the trains on the South Line do. This may encourage some passengers going to Liverpool to travel via Bankstown instead of via Lidcombe (particularly those on the Eastern part of the CBD who travel from Museum or St James stations), thus taking some pressure off the congested trains on the Inner West and South Lines. This is more evident during the PM peak, when South and Bankstown Line trains depart from different stations, whereas in the AM peak they would all depart from Liverpool.

Meanwhile, the truncation of Inner West Line services to Homebush means all trains to stations on the extremities of the Bankstown Line will now be serviced exclusively by the Bankstown Line. The loss of Inner West Line services will require passengers seeking a direct service onto the lower frequencies and longer journey times for Bankstown Line services to Wiley Park, Yagoona, Berala, or Regents Park. For those willing to make a transfer at Lidcombe, the higher frequencies and faster journeys on other lines could actually translate into a shorter overall journey.

Stopping patterns have been simplified, falling from 4 types of stopping patterns down to 2.

Inner West Line

2013-06-04 Draft SWTT 2013 Inner West PM

One fast service (stopping at Newtown, Petersham, Summer Hill, Ashfield, Croydon, Homebush) has been removed. This alone accounts for the majority of longer journey lengths in the table above.

Despite the loss of some services, maximum headways have not increased, and have actually dropped in some cases, eliminating the sometimes 18 minute long waits for the next service. This is due to the harmonisation of stopping patterns, with 1 stopping pattern for the 4 Inner West Line trains per hour, running at 15 minute frequencies, and 2 stopping patterns for the 8 South Line trains per hour, also running at 15 minute frequencies each.

The main winner here is Newtown, which will now have 8 services in the evening peak hour, up from 5, also reducing maximum headways down to 9 minutes.

South Line

2013-06-04 Draft SWTT 2013 South PM

Many stations on the South Line will have the number of services to them cut, but more harmonised stopping patterns have cut the maximum headways, which is a net benefit for most stations. Where maximum headways are up, it is generally by only 1 minute, whereas the majority will see them fall by 2 to 3 minutes. The big winners are the outer suburban stations South of Granville, which have a significant drop in travel times, as well as Flemington, where the maximum headways from from 22 minutes to 15 minutes. The main loser is Auburn, which loses its fast services from Central.

North Shore Line

2013-06-04 Draft SWTT 2013 North Shore PM

Two additional services has been added, increasing the total number from 13 to 15 in the busiest hour of the evening peak. Stopping patterns are now predominantly skip stop rather than express and all stops, making direct travel from one suburban station to another not possible. This has reduced the number of stopping patterns from 5 to 4, allowed a more even and harmonised spread of services, and reduced travel times to outer suburban stations North of Gordon. Maximum headways are down for most stations, even for those with no additional services.

The main losers are Pymble, Asquith, and Berowra, which see their maximum headways increase. Although it is only 3 minutes in the case of the first, and up to 4 of the 5 minutes in the latter 2 are made up for in shorter journey lengths.

Northern Line

2013-06-04 Draft SWTT 2013 Northern PM

This section of the network is mostly unchanged. Better timing of slots used by trains appears to have allowed services headed North of Epping via Chatswood to do so more quickly, presumably because the current timetable requires them to wait for a fast train from Strathfield to first pass before it can proceed. The other main change is the addition of additional CBD bound services from Epping via Macquarie Park. These run every 15 minutes between 3:30PM and 5:45PM, which increases the frequency between 5PM and 6PM, up from the current 4 services to 7. Maximum headways during this period drop to 9 minutes, but as the extra services end before the evening peak hour is over, the maximum headway remains 15 minutes.

Western Line

2013-06-04 Draft SWTT 2013 Western PM

Note: Cityrail claims that there are 19 trains per hour to Parramatta during the busiest hour in the evening peak, but I’ve only been able to find 18. The figures in the table above assume 18 trains, whereas the table at the beginning of this post assume 19 trains.

The Western Line has a number of long distance services where a fast train will leave Central after a slow train, then overtake the slow train and arrive at its destination earlier. These slow trains have been excluded in the above figures. In the case of Penrith, 4 services have been added due to them being slower services that still arrive at their destination before a faster service due to better timetabling.

The main improvement on the Western Line comes from more harmonised stopping patterns, leading to lower maximum headways. Some outer suburban stations, Schofields, Quakers Hill, Marayong, and Penrith in particular, have a significant decrease in journey times.

Some stations will see a slight deterioration in service, but only very minor.

Western Line/Cumberland Line (from Parramatta)

2013-06-04 Draft SWTT 2013 Cumberland PM

The addition of all day half hourly Cumberland Line services had the potential to improve access between Parramatta and nearby stations (rather than direct services from the CBD). However, as with the AM Peak, this does not appear to have occurred. Some stations will see a slight improvement, but some will see a slight deterioration.

Illawarra Line

2013-06-04 Draft SWTT 2013 Illawarra PM

As with the AM Peak, the main winners here are stations South of Hurstville, which will see journey times cut significantly. Most stations will see big decreased in maximum headways, in many cases down from 17 minutes to 10 minutes. The more simplified stopping patterns should also decrease the number of disruptions and delays.

Meanwhile, services to Rockdale and Kograh have been cut, and journey times increased by a few minutes. Those services that these 2 stations do keep will terminate at Hurstville, which should mean passengers heading to these stations will have more seats.

Correction: An earlier version of this post showed a map of the proposed Opal rollout as including stations between Granville and Liverpool. This has since been clarified by Transport for NSW as being stations between Strathfield and Liverpool via Regents Park. The map now been corrected.

Sydney’s Opal smartcard will be expanded into the rail network on 14 June 2013. It has currently operated on only 2 ferry routes, to Neutral Bay and Manly, and just 700 cards have been distributed thus far. However, passengers will not enjoy integrated fares, paying a separate fare for a journey involving both trains and ferries rather than a single fare for a single journey.

On 14 June, Opal will operate on limited sections of the ferry and rail network. (Source: Opal website)

A trial of Opal will initially operate on the Eastern Suburbs Line and City Circle, starting at Central Station. In the fourth quarter of 2013 this will be extended north to Chatswood and expanded to include all ferries. Then in the first quarter of 2014 Opal’s coverage will spread further, first to Strathfield and Wyong, then to Richmond, Emu Plains, and Liverpool (Source: Opal website).

After the initial trial on the Eastern Suburbs and City Circle Lines, Opal will then be rolled out progressively onto the North Shore, Inner West, Northern, Western, and South Lines. (Sources: Cityrail, Transport for NSW, Opal website)

The expansion of Opal into a multi-modal ticketing system will not be accompanied by multi-modal fares. Opal users who travel on just a single mode of transport will pay less than one who travels on two modes, even if their origin and destination are exactly the same. This penalises passengers for having to make a transfer via higher fares, despite this being an added inconvenience to them. An ideal fare system, one which uses integrated fares, would charge passengers based on the distance they travel, regardless of which and how many modes they use to get there.

The reluctance to integrate fares at this point may be due to the government’s choice to focus on rolling out Opal first, and fixing the fares second. The recent decision, on the advice of IPART, to correct the anomaly on ferries where a myMulti ticket was cheaper than a myFerry ticket supports this view. Fixing the other anomaly that was introduced with myZone, cheap long distance bus tickets for Northern Beaches and Northwest bus services, could be the other prerequisite to introducing full integrated ticketing.

Despite this, the $15 daily fare cap, along with the unlimited free journeys each week after the first 8, together act as a kind of integrated fare. Passengers currently need to determine the best ticket at the start of each week in order to pay the lowest fare, be it single tickets, a weekly, or a myMulti. With Opal they will be able to travel first, and then the cheapest possible fare will be charged at the end of the week. These are definitely improvements, but still retain what remains an unnecessarily complicated fare structure.

Opal cards can be obtained by ordering them online from the www.opal.com.au website. The smartcard is free, but requires a minimum $40 deposit.
