VIDEO: More than 1,500 extra weekly services for train customers, Transport for NSW (28 August 2017)

See also: 2017 timetable (part 1): Morning peak

The number of stations with a train service every 15 minutes is set to rise from 88 to 126 (representing 71% of the networks 178 stations), an increase of 43%, thanks to the addition of 1,500 additional weekly services as part of a timetable revamp set to be introduced in November. This has been achieved by adding additional services in some parts of the network and by re-scheduling services to be evenly spaced where there are already 4TPH (Trains Per Hour) on that part of the network. These 15 minute frequencies will last most of the day, 7 days a week. The government has touted the benefits of this as allowing users to ignore the timetable and instead just turn up and go.

To visualise what this means, compare the Sydney Trains map shown above to the one shown below. The map above is the normal network map, showing all the stations. The map below (the regular map, modified by this blog´s author) only shows the stations that currently receive 15 minute frequencies all day. Lines with turn up and go frequencies can be seen in Inner Sydney as well and Nothern Sydney: the T1 North Shore Line, T1 Northern Line, T1 Epping Line, T2 Inner West Line, T3 Bankstown Line, T4 Eastern Suburbs Line, and T8 Airport Line.

The map shown below also includes the stations that are set to get 15 minute frequencies in November. These new stations are mostly in Sydney´s West: the T1 Western Line, T2 Leppington Line, and T8 South Line. The main lines still missing a regular all day 15 minute frequency are the T1 Richmond Line, T4 Cronulla Line, and the T4 Illawarra Line. The T1 Richmond and T4 Illawarra Line are hampered by being branch lines that service sparsely populated areas, meanwhile the T4 Cronulla Line does have 4 trains per hour, but enter the city on 10/20 minute frequencies due to varied stopping patterns.

Additionally, where branch lines with 15 minute frequencies merge in the inner portions of the network it results in even higher frequencies. Most of these stations thus provide all day frequencies of a train every 10 minutes or less, with a few providing frequency levels of a train every 11 minutes or less (often in one direction rather than both directions). The highest frequencies are seen on the City Circle, where trains travelling through in a clockwise direction pass through stations every 6 minutes or less all day.

There are 3 areas in particular, accounting for 27 stations, where this occurs:

  1. The T4 Cronulla Line and T4 Illawarra Line merge at Sydenham to provide 6TPH, resulting in even 10 minute frequencies between Sydenham and Bondi Junction.
  2. The T8 Airport Line and T8 South Line merge at Wolli Creek to provide 8TPH, resulting in 6/9 minute frequencies between Wolli Creek and Central via the airport stations in both directions. Services through the City Circle, entering via Museum and travelling counter-clockwise, continue this 6/9 minute frequency.
  3. The T2 Leppington Line, T2 Inner West Line, and T3 Bankstown Line merge at Redfern to provide 12TPH, resulting in 3/6 minute frequencies through the City Circle, entering via Town Hall and travelling clockwise, though to Central.
  4. The T2 Leppington Line and T2 Inner West Line merge at Ashfield to provide 8TPH, resulting in either 7/8 minute or 4/11 minute frequencies into the City Circle for Ashfield and Newtown Stations. Frequency levels depend on direction of travel and whether it is a weekday or weekend. However, Newtown´s 15 minute frequencies remain on weekends.
  5. The T1 Western Line and T1 Epping Line merge at Strathfield to provide 8TPH, resulting in 6/9 minute or 4/11 minute frequencies into the City and through to Chatswood for Strathfield Station. Frequency levels depend on direction of travel.

The stations affected can be seen in the map below.

Commentary: Why frequency matters

This blog has argued the merits of high frequency networks before (see: here, here, here). A network of high frequency public transport services, buses as well as trains, with easy interchanges between them, allow for a much greater level of mobility for its users.

The big increase in the 15 minute turn up and go network is to be commended. This will go a long way to improving access to the Sydney CBD. But for users wanting to make a transfer at an interchange, be it catching a bus to their local station or changing trains at an outer suburban station, a 15 minute frequency is just too long.

That´s why identifying where services are more frequent than a train every 15 minute is so important. As it turns out, 27 stations in and near the city currently do; reaching Chatswood, Bondi Junction, Wolli Creek, and Strathfield. Most of these have gaps between train services of no more than 10 minutes, with the best service levels seen on the City Circle for anyone travelling through it on a clockwise direction of a train every 6 minutes or less all day.

But there is still scope for improvement that requires little to no additional spending on operating costs. Here are some suggestions:

  1. Re-schedule trains on T1 between Strathfield and Chatswood to eliminate the 11 minute gaps between some services. This would allow for a train every 9 minutes or less all day without having to add more trains.
  2. Look into making express trains on T2 stop at Newtown during weekends to give that station 8TPH across the full week. Both these changes may be possible without having to add more trains.
  3. Re-route trains on T3 to run through the City Circle via Museum and then terminate at Redfern where they can turn around at the Macdonaldtown turnback and return to Bankstown through the City Circle. This would increase frequencies through the City Circle up to 12TPH in both directions, providing a train every 6 minutes or less all day with only a small increase in cost.
  4. Re-schedule trains through the City Circle to have even spacings. Where there are 12TPH, this would mean a train every 5 minutes rather than 3/6/6 minute gaps in the frequency as is currently the case. It would result in 5/10 minute frequencies in other parts of the network, rather than 6/9 minute frequencies, such as the Airport Line.

In the longer term, the two new Sydney Metro Lines should result in a large increase to the all day high frequency network out to Rouse Hill, Parramatta, and Bankstown. Sydney Metro Northwest is currently slated to run at 10 minute frequencies all day. When it gets extended through to Bankstown increasing its frequencies up to a train every 5 minutes all day would be a big improvement that would achieve the earlier stated goal of providing a true turn up and go network that makes interchanges easy and seamless.

Two thirds of stations on the Sydney Trains network will enjoy a train to the city every 15 minutes during most hours of the day on both weekdays and weekends under a revamp of the train timetable set to be implemented in late November. The plans will also see a boost to peak hour services, with the number of trains entering Sydney´s CBD stations increasing to 114 during the busiest hour of the morning; a 3.6% increase on the existing 110 trains per hour, while Liverpool will see the addition of fast express trains into the city during the morning peak.

The new timetable is accompanied by a new network map (shown above), which was reviewed by the Transit Maps website.

All up, an additional 1,500 services are being added per week. Half of these during the weekend. For comparison, the 2013 timetable changes saw an increase of 700 services per week, with no change to the weekend timetable. The increase in service levels will be supported by a $1.5bn capital investment, the largest part of which will be the purchase of an additional 24 Waratah trains. This will increase the existing fleet of Waratahs trains from 78 to 102.

This post will look at how the changes affect the morning peak hour. A future post will focus at the off-peak.

The Good

The number of trains into the city from Parramatta is set to increase from 20TPH (Trains Per Hour) to 24TPH. If the 4TPH on the Blue Mountains Line which stop at Parramatta but terminate at Central´s Sydney Terminal are included, Parramatta will soon see 28TPH into Central Station during the busiest hour of the morning peak.

It achieves this by extending the T2 Inner West Line to Parramatta, with 4TPH on that line now starting at Parramatta rather than Homebush. This was one of the few ways to increase capacity into the city from Parramatta, as the Western Line is currently at maximum capacity of 20TPH.

The new timetable then resolves the issue of overcrowding on the T2 Line from additional passengers boarding at Parramatta by adding an adding additional capacity on the T2 Leppington Line and T3 Bankstown Line. It is able to do this as these both run into the City Circle, which is the only line with significant spare capacity. The City Circle currently uses 34 out of the 40 paths (that being 20TPH in each direction) available during the busiest hour of the morning peak. The new timetable adds an additional 4TPH into the city, meaning that 38 paths out of a potential 40 will now be used. As a result, the T3 Bankstown Line will see an increase from 8TPH to 10TPH, and the T2 Leppington And Inner West Line will see an increase from 12TPH to 14TPH. This should, in theory, offset the loss of 4TPH to Parramatta.

The Bad

The increase in services through the City Circle now mean that Sydney’s city stations are one step away from being full during peak hour, with 114 of the available 120 paths on the 3 CBD lines being used up. This is 95% of maximum capacity.

With demand on the rail network currently growing at a rate of 10% per year, there is a risk that the network will reach capacity well before additional rail capacity comes online in 7 years when the Sydney Metro is extended through under the CBD in 2024.

The only other viable stop gap would appear to be an increase in services into Sydney Terminal. Internal government plans prepared in 2014 show this could increase capacity into Central Station by 16% during the busy morning peak, but it would cut many direct services between the city and Sydney´s outer suburbs. The current timetable goes part of the way in doing this by rerouting some T1 Richmond Line services through to the T5 Cumberland Line, but for now Richmond retains direct services into the city.

The Ugly

The T2 and T3 lines will now have some very unusual stopping patterns during the morning peak. Some stations on theT3 Bankstown Line will now have a 19 minute gap between services during the morning peak. This seems designed to cater for the new Liverpool express services.

It is unusual because this undoes part of what the 2013 timetable changes aimed to do: simplify the timetable to create regular clockface timetable. Strangely, those same stations still enjoy regular 15-minute clock face frequencies during the off peak hours of the day.

To complicate things even further, there is a possibility that these unusual stopping patterns will not survive past 2024, when the Sydney Metro City and Southwest absorbs the Bankstown Line.

The Sydney Trains network contains 178 stations. 25 of these stations have all day 10 minute frequencies. This is mostly in the CBD, Eastern Suburbs, Airport Line, and Lower North Shore Line.

Prior to 2013 this high frequency network was even smaller, consisting only of the 9 stations on the T4 Line between Wolli Creek and Bondi Junction. This remains the case on weekends, with the 2013 timetable improvements only applying to weekdays and not weekends.

In addition, the T1 Line between Strathfield and Chatswood does have some 11 minute gaps which have been counted as 10 minute frequencies even though the technically do not meet the strict 10 minute criteria. But stations like Hurstville in the South and Parramatta in the West, serviced by 7 and 9 trains per hour respectively, do have 10 minute frequencies if measured at Central Station; however different stopping patterns prevent them from having evenly spread out 10 minute frequencies outside of the CBD.

This distinction is important; as a rule of thumb passengers generally value waiting time twice as much as their travel time. The result of this is that a passenger would rather spend 25 minutes travelling on a train than 10 minutes waiting for a train followed by 10 minutes on the train. The 10 minute waiting time is worth the same as 20 minutes of actual travel time, therefore the second option feels like a 30 minute journey and so passengers would often opt for the first option of 25 minutes. This is even though the first option involves a longer total journey time.

This high frequency network could hypothetically be expanded by changing the stopping patterns of some trains. This eliminates the need to provide additional services, though may sometimes necessitate additional train revenue service hours. This is not an exhaustive list. For example it leaves out stations like Newtown which could achieve 10 minute frequencies by having all T2 Line trains stop there, rather than just the current 15 minute frequencies resulting from half the T2 Line trains that do stop there.

  1. T1 trains that stop at Strathfield to also stop at Burwood. There are technically trains every 10 minutes at Burwood, but the T2 trains are so slow that they arrive in the CBD after the T1 trains. So what is needed here is for some more of the 13 T1 Line trains that stop at Strathfield every hour to also stop at Burwood.
  2. T4 trains that stop at Sydenham/Wolli Creek to also stop at Tempe. The trains that skip Tempe are not timetabled to run any faster than those that stop there, so this could be done without slowing down the timetable.
  3. T1 and T5 trains between Blacktown and Harris Park to add stops at intermediate stations spaced evenly apart. While the T1 Line has 7 trains per hour passing through this section of the network, there are also 2 trains per hour on the T5 Line, resulting in 9 trains per hour in total. This would not provide 10 minute frequencies into the CBD, but would provide 10 minute frequencies for those getting a train to/from Parramatta or Blacktown.

The Sydney Trains network actually looks a lot better when all day 15 minute frequencies are the benchmark. 113 stations out of 178 (63%) have 15 minute frequencies. This is high enough for turn up and go journeys when only 1 train is required. However, if a transfer is required; such as to another train or between bus and train; then 10 minute frequencies are a much better benchmark for turn up and go services.

Meanwhile, the 10 minute frequency network is set to expand dramatically in 2019 and then 2024 when the 2 stages of the Sydney Metro project are scheduled to begin operation. This new line will also run at 10 minute all day frequencies, and extend these frequencies further out into the outer suburbs of Sydney than is currently the case.

Hits

Happy New Year. 2013 has been an eventful one. This blog received almost 138 thousand hits during a year in which:

In the coming year, we can look forward to the opening of the Inner West Light Rail extension to Dulwich Hill and the completion of the Opal rollout (currently scheduled for the end of 2014). Meanwhile, expect the major parties to begin to announce their transport plans ahead of the next state election in early 2015, with things like a Second Harbour rail crossing, a Western Sydney light rail network, Bus Rapid Transit for the Northern Beaches, and potentially plans to privatise the state owned electricity transmission network as a means to pay for all the much needed infrastructure all likely to feature prominently.

But until then, here are some of the major events and stories from the past year, as posted, shared and commented about on this blog —

The clear thing in common here is the North West Rail Link (NWRL), which tends to generate a lot of discussion back and forth in the comments section. The post on the Macquarie Park light rail was the most commented on post and not actually about the NWRL, but the comments soon shifted towards discussing the NWRL.

This probably understates the level of sharing over Twitter as tweets are only counted once, regardless of how many times that one tweet may be re-tweeted, whereas Facebook shares are each counted uniquely. That said, the most shared posts have tended to be driven by shares on Facebook rather than tweets on Twitter.

WestConnex was by far the biggest generator of hits from web searches, with the home page being the destination rather than the post itself (preventing those posts about WestConnex from ranking higher) and reflects the fact that the car remains the primary mode of transport for Sydney residents. This is in contrast to activity in the comments section and social media, both of which are more likely to be transport enthusiasts, neither of which had WestConnex in their respective top 5 for the year.

This does perhaps provide a reminder to some advocates of public transport (the writer of this blog included) that there remains some disconnect between them and the regular person on the street when it comes to enthusiasm for public transport and dislike of cars or roads.

The opening of the South West Rail Link (SWRL) connecting Leppington to Glenfield will result in the biggest change to the Sydney Trains timetable since the just implemented 2013 timetable came into effect in October (all figures below are based on this newly introduced timetable). The major question over how it will be integrated into the network revolves around the need for rolling stock.

The government has recently passed up the opportunity to increase its fleet of Waratah trains by an additional 8 to 12 above the currently planned 78 trains. These additional trains would allow the network to operate entirely with air conditioned trains, and without them it will instead have to operate some of the older S-Set trains (which are currently being phased out for lacking air conditioning). The government is retaining about 24 of the S-Set trains for this.

The non-air conditioned trains may not necessarily operate on the SWRL, and which ever line they do end up on will probably only use them during peak hour when the need for trains is at its highest.

The amount of rolling stock requires will depend on which line the SWRL will be connected to. One option involves running the SWRL via the East Hills and Airport Line. In the morning peak there are currently 2 East Hills Line trains per hour starting from East Hills, running limited stops to the CBD via the Airport, which could be doubled to 4 and then extended to Glenfield to link up to the SWRL. This has the advantage of being fast (42 minutes from Glenfield to Central), being relatively uncrowded (the East Hills and Airport Line could have approximately 109 passengers per 100 seats after the October 2013 timetable is implemented), and having spare capacity for adding 2 more trains per hour – which would reduce this overcrowding. However, this would require additional rolling stock, both through the doubling of existing peak hour services from East Hills from 2 to 4 trains per hour and their extension to Glenfield (where the SWRL begins).

The alternative is for the SWRL to operate as an extension of the South Line. During the morning peak hour there are currently 4 South Line trains per hour starting from Glenfield, running limited stops to the CBD via Granville. This has the advantage of not needing to add additional services or extend them, as 4 trains per hour already start at Glenfield. However, this route would result in a much longer journey (61 minutes from Glenfield to Central), is relatively crowded (the South Line could have approximately 114 passengers per 100 seats after the October 2013 timetable is implemented), and has no spare capacity for running additional trains without altering the way in which South Line and Inner West Line trains operate. This is because South Line trains run express from Strathfield while Inner West Line trains run all stops, but the lack of overtaking tracks reduces the maximum hourly capacity from 20 trains per hour down to 12.

Once the Bankstown Line is linked up to a Second Harbour Crossing and its trains removed from the City Circle, an additional 4 trains per hour can be added to the East Hills Line during the AM peak. However, the South Line will retain the same constraints previously mentioned. Additionally, should an airport ever be built at Badgerys Creek then an extension of the SWRL and East Hills Line could connect the new airport to Kingsford-Smith Airport with a continuous rail line.

Despite this, in both cases it would be possible to run all SWRL trains via the South Line and still maintain a quick and easy cross platform transfer at Glenfield. By sending all South and Cumberland Line trains through the SWRL, it would also allow independent operation of the lines to Leppington and Macarthur from Glenfield. This would prevent delays on one section of the line from immediately flowing on to the other section. This “sectorisation”, as it is known, would be even more pronounced once single deck metro trains run on the Bankstown Line and it is truncated to Cabramatta.

A similar challenge exists during the off-peak. Here are 3 possible options:

  1. The South Line currently operates at half hour frequencies, and these 2 trains an hour can be re-routed to the SWRL. This removes two services per hour from Campbelltown, albeit trains so slow that passengers can reach the CBD faster by waiting for the next East Hills train and catching that instead.
  2. Two trains an hour on the East Hills Line (one each starting from/terminating at Kingsgrove and Campbelltown) could each be re-routed to the SWRL. This removes one service per hour from Campbelltown, bringing it back down to half hourly services all day. Though some clever timetabling of the Cumberland Line could allow passengers South of Glenfield a quick transfer at Glenfield for a fast SWRL train into the CBD, reducing the 30 minute wait between trains.
  3. The Cumberland Line is re-routed to the SWRL. This removed a direct link to Parramatta for anyone South of Glenfield and a direct link to the CBD for anyone on the SWRL. This makes it an unlikely choice, if passengers are required to make transfers then it should be for those with non-CBD destinations.

The SWRL was recently announced to be running 12 months ahead of schedule and $100m under budget. However, the revised mid-2015 completion date is still 3 years behind the initial 2012 completion date, with the revised $2.0bn budget well above the $688m it was originally expected to cost (Source: Daily Telegraph).

This Thursday, the writer of Transport Sydney will be joining a few other brave souls in attempting the All Day Challenge (previously known as the Cityrail Challenge) and try to travel to all 176 train stations in the Sydney Trains network in a single day. This is one of the final opportunities to do so under the current timetable before the new timetable comes into effect on 20 October. Under the new timetable, Inner West Line trains will no longer operate past Homebush, but the Cumberland Line will operate all day rather than just during peak hour.

Facebook group has been setup and rules posted. In brief, the rules are:

  • Participants must begin and end at Central Station.
  • All 176 stations in the Sydney Trains network must be passed at least once on a train that stops at that station
  • Travel must be by train only. Leaving a station is allowed for breaks, but travel must recommence from that station
  • Points are awarded for being first to stop at a station, travelling on different train sets, being first back to Central, etc

Anyone wanting to keep track on the day can either follow the action on the Facebook page or on Twitter with the hash tag #AllDayChallenge.

2013 timetable finalised

The government announced today the final version of the October 2013 timetable. Much has been written on this topic in this blog so far this year, so links to that have been included below rather than just repeating it all over again.

One of the less publicised improvements is the extension of the 10 minute frequency network. Currently, trains on the Eastern Suburbs Line between Bondi Junction and Sydenham run every 10 minutes between 5AM and 9PM on weekdays. This will now be extended through to midnight. Meanwhile, trains on the North Shore Line between Central and Chatswood will run every 9 minutes (Southbound trains) and 11 minutes (Northbound trains) between 5AM and 9PM, while trains on the Airport Line between the City Circle and Wolli Creek will also run every 9 minutes between 6AM and 10PM.
