Plan for Metro lines to South East Sydney

The NSW government has released the South East Sydney Transport Strategy and included in the preferred scenario two new metro lines to be built by 2041 and 2056.

The Strategy outlines how Transport for NSW expects to respond to growing population in South East Sydney, an area of the city stretching from Redfern to La Perouse and to Rockdale.

The first metro line would extend from the CBD to Green Square, and Randwick and terminate at La Perouse. The second would begin at Randwick and travel to Kogarah via Sydney Airport.

The CBD to La Perouse metro line would be an extension of Sydney Metro West, and is the first Metro line to be completed, in 2041.

Metro between Randwick and Kogarah would be delivered by 2056 and would extend beyond Kogarah to Miranda.

In addition to the new metro lines, a rapid bus network would link the south east. A Transport for NSW spokesperson said that the combination was preferred over light rail options.

“After considerable consultation with Councils and other key stakeholders, two new Metro lines were considered to be the most effective means to provide for the transport needs of South East Sydney into the coming decades. Light Rail was considered, but a Rapid Bus and Metro combination allowed for better outcomes in terms of delivery and connectivity.”

The Strategy also assumes that metro will connect Hurstville and Macquarie Park and Kogarah and Norwest.

The Strategy acknowledges that current transport infrastructure in the region is not meeting the needs of the population.

Stations on the Airport Line, the only heavy rail line that runs through the region, reach capacity by 7.15am. With three in six trains arriving over capacity and four in six trains departing over capacity between 7.45 and 8.45am. With further development forecast along the line there is a need for greater capacity.

“Transport for NSW recognises that as South East Sydney continues to grow over the coming 30 years, new lines will be needed to support existing infrastructure,” said the Transport for NSW spokesperson.

The Strategy also covers the Port Botany area and while not recommending further rail to the port beyond the Port Botany Rail Line Duplication project, does set out as an objective that Port Botany has “easy access by all modes to local commercial, industrial and employment precincts.” The Strategy however does not include passenger rail to Port Botany, only recommending that Port Botany be connected via bus and private vehicle to the rest of Sydney.

The Strategy marks a shift in transport planning for the South East region of Sydney. Instead of taking a “predict and provide” approach, the Strategy identifies a vision for the region and then indicates the proposed transport infrastructure. As written in the Strategy:

“This approach recognises that continuing to accept current mode share, and in particular high levels of private car use, is not going to realise the vision, rather it will lead to increased road congestion and reduced accessibility for local residents, workers and visitors.”

Sydney Metro seeking industry contribution to potential Pyrmont station

The NSW government is increasingly closing in on confirming Pyrmont as a station for the new Sydney Metro West line, which will run from Westmead via Parramatta to the Sydney CBD.

While stations have been confirmed at Westmead, Parramatta, Sydney Olympic Park, North Strathfield, Burwood North, Five Doc and The Bays in Rozelle, a question mark has hung over a station in Pyrmont.

This week, Sydney Metro released an invitation to participate to the private sector for a potential Metro station at Pyrmont. The market engagement process aims to provide feedback on the scope for financial and/or non-financial contribution from the private sector and/or commercial beneficiaries to a station in Pyrmont.

The engagement will include written submissions and one-on-one meetings with selected participants. The invitation to respond names landowners, business, other private sector and commercial entities as potential participants.

This engagement with the private sector follows the release of a planning strategy for the Pyrmont Peninsula, which includes multiple mentions of a potential station. The station would support the strategy’s vision for a connected and low-carbon peninsula. The strategy hopes to realise the benefits of a new station by making Pyrmont a “destination, rather than a point where journeys start”.

Announcing the strategy on July 31, Minister for Transport Andrew Constance said that options were still being considered for the station.

“We’re still working through the potential for a Metro station in Pyrmont, but it has progressed to the next stage of the process.”

A new Metro station has previously been touted as a way to extend the Sydney CBD and connect the two peninsulas.

Constance said that further connections to Western Sydney would be required.

“Connecting Pyrmont with Western Sydney would encourage jobs, investment and economic growth. My job is to ensure the area is easily accessible and has the right transport options in place.”

Sydney Metro

Preparations taking place for next stage of Sydney Metro

Civil works are underway and stabling facilities are being constructed to connect the existing Sydney Metro line with its extension to the City and Southwest.

In Rouse Hill, the current stabling yards are being expanded with a new test track, stabling roads, and overhead wiring.

The enlarged depot will provide space for the extra 37 trains which will run on the expanded Sydney Metro line when it continues from Chatswood, via the Sydney CBD and onto Bankstown.

Systems Connect, a partnership between CPB Contractors and UGL Engineering is delivering the works, of which over 3.1 kilometres of track and 6,500 sleepers have been installed. Twelve thousand tonnes of ballast has also been delivered.

The facility will be operational by the end of 2021 and all works will be complete by 2022, ahead of the new line opening in 2024. A Sydney Metro spokesperson said this lead time would allow for bedding in the new rollingstock.

“The expanded depot will be used for testing and stabling of the new metro trains as they progressively arrive.

“New metro trains will arrive well in advance of the opening date for the necessary testing – there will be further updates closer to that time.”

At Chatswood, foundations are being laid to connect the existing Metro North West line to the tunnel which will take trains under Sydney Harbour before emerging in Sydenham.

Work has had to be delivered in a 48-hour shutdown of the current suburban rail services, to reduce disruption. 130 workers have been on the project, including moving 330 tonnes of soil, using piling rigs to drill 34 holes up to 8 metres deep. Future works will involve excavating 7,500 tonnes of material and repositioning the existing suburban rail line.

Limiting resources and using recycled materials has been a key focus of the project, both in the first stages of Sydney Metro and current upgrade works.

At the new stabling facility in Rouse Hill, crushed recycled glass used to bed down pipes, instead of sand, using 1,000 tonnes of recycled glass. Recycled road base made of old crumbled concrete is used to make the hardstands for laydown areas and a car park for staff.

Water saving measures include using recycled water, such as rainwater and runoff. Dust block is used to bind fine dust, instead of water.

KTK Australia denies forced labour allegations

Allegations that slave labour was used in the production of components used in a number of Australian rollingstock fleets have been strongly denied by KTK Australia.

In a statement, KTK Australia said that such allegations “are based on no official documents, interviews or testimony”.

The allegations stem from a US Department of Commerce blacklist that included KTK Australia’s parent company, KTK Group. The US Department of Commerce said that KTK Group was implicated in human rights violations such as the forced labour of Muslim minority groups from Xinjiang Uyghur Autonomous Region.

KTK Australia disputed the basis for these implications.

“KTK Group has never employed workers who are members of the Uyghur ethnic minority,” said the KTK Australia statement.

KTK Australia’s website lists its components as in use on a number of Australian rollingstock fleets. These include NSW’s New Intercity Fleet (NIF), and Sydney Metro, the X’Trapolis and High Capacity Metro Trains (HCMT) in Victoria, and Queensland’s Next Generation Rollingstock (NGR).

Bombardier, which manufactures the NGR fleet, said that it was closely looking into the allegations.

“Bombardier Transportation is aware of the recent action by the United States Commerce Department in relation to KTK Group Co. We are actively monitoring this new dynamic – impacting the transportation industry – and any effect this could have on our own supply chain, projects and products,” said a Bombardier Transportation spokesman.

In Bombardier’s Supplier Code of Conduct, which all suppliers must agree to, forced labour, modern slavery, and human trafficking are explicitly prohibited. The code outlines:

Bombardier will not engage in the use of forced or enslaved labour or human trafficking, nor will it tolerate their use at any level in its supply chains. Suppliers must not demand any work or service from any person under the menace of any penalty. For example, Suppliers’ employees must be free to leave work or terminate their employment with reasonable notice, and they are not required to surrender any government issued identification, passports or work permits as a condition of employment.

Alstom, which manufactures the Sydney Metro and X’Trapolis fleet, also prohibits forced labour in its supply chain. Its Ethics and Sustainable Development Charter requires that suppliers commit to the “elimination of all forms of illegal, forced or compulsory labour”.

A Victorian Department of Transport spokesperson said that it was assured that there is no evidence of forced labour in the supply chains of its rollingstock.

“We have asked our manufacturers to take additional steps to ensure the integrity of their supply chains, and we continue to monitor the situation and will consider further steps based on the outcomes of ongoing supply chain investigations.”

A Transport for NSW spokesperson highlighted that suppliers must comply with Australian laws covering subcontracting and reporting requirements.

“Transport for NSW also has rights to access and audit the supplier’s records and the materials, goods, workmanship or work methodology employed at any place where the supplier’s activities are being carried out.”

The NSW spokesperson said that the components in use on the NIF were from the French arm of KTK.

In a report published by the Australian Strategic Policy Institute (ASPI), which is in part funded by the US State Department, KTK Group is named as one company that was involved in the transfer of Uyghurs out of Xinjiang. The report cites online news articles.

KTK Australia noted that the cited articles refer to non-Uyghur workers from Xinjiang constructing a playground in a city in Jiangsu province.

“KTK Group confirms that in 2018-19 it did employ a small number of workers from Xinjiang, who were not ethnically Uyghurs, all were properly employed and paid the same wage as all KTK other workers in the same positions,” the KTK Australia statement read.

The US Department of Commerce blacklist prohibits US companies from working with listed companies. KTK Group has no investments in the US and said the decision would not have a material impact on the business.

“KTK Group is a transparent company and we welcome any international customers to inspect our facilities and to audit our labour practices.”

Alstom to trial fully autonomous shunting in the Netherlands

French rail manufacturer Alstom has signed an agreement with Dutch infrastructure operator ProRail to test automatic shunting locomotives in 2021.

The tests aspire to a level 4 grade of automation (GoA4) where the trains will be fully automated, a first for shunting trains in the Netherlands.

Alstom will fit the automatic train operation (ATO) technology to diesel-hydraulic shunting locomotives owned by Lineas, the largest private rail freight operator in Europe. This technology will include automatic control technology, intelligence obstacle detection, and environment detection.

During the tests, train staff will remain aboard to ensure safety, however regular tasts such as starting and stopping, pushing wagons, controlling traction and brakes, and handling emergencies will be fully automated.

Bernard Belvaux, Alstom managing director for Benelux said that the trial would improve the operation of railways.

“This project is paving the way for fully digitalised railway. These tests will help the European rail system benefit from an increase in capacity, reduced energy consumption and cost while offering higher operational flexibility and improved punctuality. This test is fully in line with Alstom’s strategy to bring added value to our customers for smart and green mobility.”

Alstom has previously delivered ATO for metros around the world, including on the Sydney Metro, where the system also runs at a GoA4 level. This experience has enabled Alstom to demonstrate the benefits of an automated railway. By reducing headways and operating uniformly, automated trains can increase capacity, cut costs, and save energy.

ProRail has previously carried out tests with freight locomotives at GoA level 2, where a driver remains in control of doors and in the event of a disruption, with Alstom on a freight locomotive on the Betuweroute, a freight railway running from Rotterdam to Germany.

In May, Alstom announced that it would be trialling ATO on regional passenger trains in Germany in 2021.

Planning process accelerates over a billion dollars of NSW rail projects

NSW Planning Minister Rob Stokes is accelerating three major rail projects as well as development above the new Crows Nest Metro Station and around the CBD and South East Light Rail.

Stokes said that moving projects such as the $700 million Inland Rail from Narrabri to North Star, the $273m Botany Rail Duplication, and the $115m Cabramatta Rail Loop would enable the state to economically recover from coronavirus (COVID-19).

“The fast-tracked assessment program is a key part of the NSW Government’s COVID-19 Recovery Plan as we continue to get shovel-ready projects out the door to keep people in jobs and keep the economy moving.”

The proposal to revamp of Central Station as part of the Western Gateway project will also be accelerated. Transport for NSW is proposing new planning control to enable the development of a technology centre adjacent to the rail corridor.

All projects will be determined by August 14, 2020.

Australasian Railway Association (ARA) CEO Caroline Wilkie welcomed the announcement by Stokes.

“It is good to see the NSW government recognise the significant community benefits rail delivers by accelerating these projects,” she said.

“Infrastructure investment will be the cornerstone of our economic recovery and sustainable, long term rail projects will form an important part of that.”

Completion of the Inland Rail section as well as the Port Botany duplication and Cabramatta passing loop will improve NSW’s freight rail network, enabling further growth and reducing trucks on roads in Sydney and regional NSW.

Rail’s role to play in activating development in other precincts has been recognised in the proposal to increase building height and floor space controls near the light rail line in Kingsford and Kensington. In Crows Nest, Sydney Metro is proposing to increase the building height and floor space controls to enable development above the new station.

“This is a great example of improved project approvals processes making a real difference for businesses, jobs and the people that depend on them,” said Wilkie.

smart signal

Delivering a next generation smart signal

Required to develop a unique solution for a challenging requirement, Aldridge have implemented a smart signal built for the future.

Across the vast majority of most train networks, most signals have the sophistication of a light bulb – the signal is either on, or off. The increasing sophistication of new lines, and their requirements to deliver more in a smaller package, has required a new kind of smart signal.

Sydney-based rail signalling experts, Aldridge have developed a new smart signal which can provide a much greater amount of information in a tight environment. Already in use in some of the most advanced systems in the Asia-Pacific region, David Aldridge, managing director of Aldridge, explains what makes these signals smart.

“In a conventional signal, you might have an A or B on it, and then if you need to put a C on there you can’t do it; you need to build a whole new signal. This one you can reprogram to show an A, B, C, D, or whatever, that’s the difference – their ability to be able to generate all characters.”

The new signal can decode up to 10 110VAC selection inputs and generate a comprehensive range of alphanumeric characters and symbols on displays up to three digits wide. This solution was developed in house, as company engineer Craig Sharwood highlights.

“I can change a lot of the behaviour of the display that previously would be locked in hardware and any change would require a major change to circuit boards and documentation. Here I can just change the code that controls the signal and change an A to a B or a 1 to a 5.”

The flexibility of the signal does not end at the display, however, as it can be configured with any number of interlocking systems and has already been installed in divergent projects.

“The structure of the signal is such that I can adapt it to be compatible with whatever interface I have to connect the signal to,” said Sharwood. “it gives us some flexibility to make it talk and in whatever format that the customer would like.”

A PROVEN SOLUTION
The smart signals were first developed to be used on two projects in Southeast Asia, the MRT Purple Line in Bangkok and the KVMRT system in Kuala Lumpur. For both systems, Aldridge had to comply with the customer’s demand for a new kind of signal.

“The customer’s challenge required our signal to display numerous character combinations using encoded 110VAC signalling over a limited umber of control lines.

Our solution enabled this customer to achieve the desired signal display functionality at lower cost, by reducing cable harness conductor count and interface overheads,” said Sharwood.

With the technology proven on these projects, when the call came for a similar signal for the Sydney Metro Northwest project, Aldridge was able to supply their solution.

“We’d already designed the product for the two other projects in Asia,” said Aldridge.

“We had the technology running and then we reproduced it here using the same technology.”

Although the core technology was the same, the signal had been improved as a result of previous versions, giving the product an edge over other solutions, said Sharwood.

“We have refined it over several iterations with other clients, so it’s given it maturity as a product. It’s not just a drawing board situation, it’s something that’s in service.”

While the product had been updated, the size of the kinetic envelope on the Sydney Metro lines presented a new obstacle for Aldridge to overcome.

“One of the challenges was the actual size that they gave us which we had to bring the product down to, to miniaturise it,” said Aldridge.

“A normal signal here in Australia, or basically anywhere in the world, is 300mm in width and these had to brought down to 270mm.”

In bringing down the size of the signal, Aldridge also developed the system to be modular, so that it could continue to fit into the diverse requirements of each future rail project. For Sydney Metro, the signals combine a points position indicator, which indicates left, straight ahead or right, with a red horizontal bar for stop, and a separate main route indicator number. The two displays are electrically isolated, and the arrangement can be modified for the variation required.

“Every company has their own interlocking system – they’re all a little different – and then they also have different group requirements for reporting back to the controller from the signal, what happens in fail mode, and all those little parameters,” said Aldridge.

Being able to approach each project on its own terms with an applied solution that can be modified to fit has allowed Aldridge to step in on projects when other have pulled out at the last minute.

Four typical examples of how the smart signals could be configured, showing the route number and points direction.

DESIGNED TO BE SAFE FOR FUTURE APPLICATIONS
Currently, the signal is used as a non-vital signal on the Sydney Metro network. Aldridge has delivered 153 signals, including 55 smart running, 26 smart shunting, and 72 buffer stop signals, across the Sydney Metro project so far. Although automated, the system requires signals for manual operations, including shunting, that must be fully operational when the Metro is running.

As part of the safety measures in the signals, the two separate indicators can be monitored independently, while also performing their own self testing in a loop configuration.

“The most recent model is a higher safety integrity level (SIL) level than the original, so it monitors its own power supply and it monitors its outputs. It has a status output to say basically ‘I’m ok or not ok,’ so it’s not a signal that can be used for controlling, generating a stop, but it has sufficient reliability and controls built in to make it more than adequate for this non vital application,” said Sharwood.

While the current signal is not being used to convey a movement authority, the fundamentals of the system are such that further deployments could use the signal in what Sharwood terms a hybrid manner.

“The Aldridge smart signal has the potential to displace a lot of normal signals. Rather than just displaying characters in the array, on the same array it could be displaying signalling information.

“At the moment we’ve kept it separate, the smart signal is displaying digits and characters and we still have more conventional bar signals, but it’s possible with the right approach that we could have characters and arrows, bars, all sorts of different types of signalling, embedded in the display.”

THE ALDRIDGE DIFFERENCE
The development of the innovative smart signal required a different set of skills than what is normally required of a signal engineer, however just as mandatory was the existing expertise Aldridge had in hardwired signals.

“We have leveraged some components that we know are good and the rail industry feels comfortable using and re-using. We’ve used a small number of components that we know are basically the stalwarts of the industry and our product range and added the technology and added the smarts to succeed and satisfy customer requirements,” said Sharwood.

While the 5mm LED lights and other componentry may have resembled existing signals, there was a considerable amount of new thinking involved in the design.

“These signals bear almost no resemblance to any predecessor signals so in a lot of ways we had to start from scratch and basically design something completely new,” said Sharwood.

Pulling this exercise off however required belief from the top down.

“A lot of industries like rail get stuck with the things they know and the things that work over and over and suddenly that isn’t enough” said Sharwood.

“At some stage we have to go, ‘Ok, I have to make a big leap into modern technology.’ That’s what Aldridge did in this case.”

This approach is where Aldridge has been able to distinguish itself in its ability to find the right solution, with 70 years of experience and 30 within the rail industry.

“In general, we lead the customer a little bit in terms of what could possibly happen,” said Sharwood.

“They look to us to say, ‘How do we actually use this signal?’ Even down to the point of what size fuses should be used, what earthing should we have.

“Sometimes we assist the customer on their side of the fence to help them integrate into their network, and into their systems,” said Sharwood.

Integrated signalling systems providing reliability on Sydney Metro

After a year of successful operations, Alstom is embedding signalling knowledge and experience from Sydney Metro into the local rail industry.

On May 26, 2020 Australia’s first fully- automated, driverless metro system completed its first year of operations. The service had already carried 20 million passenger trips across 105,000 services and was winning fans in its commuters for its frequency, reliability, and speed, having an overall customer satisfaction rating of 96 per cent.

Beyond the staff on the ground and the physical infrastructure itself, what was ensuring these high customer satisfaction metrics was the reliability of the innovative signalling system deployed on Sydney Metro.

For the project, Alstom supplied its Urbalis 400 Communication Based Train Control (CBTC) signalling system, which in the case of a driverless train such as Sydney Metro has a fundamental role to play in smooth operations between the train, the platforms and the control centre.

Although a first for Australia, this was not the first time that the Asia-Pacific region had seen the deployment of this system. Singapore was the first city to use a similar Alstom CBTC system, on the North East Line in 2003. One of the recent cases, however, was the extension of Hong Kong’s metro system known as the South Island Line, which shares an operator with Metro Trains Sydney (MTS) with MTR. This made for a smooth adaption of the technology to local conditions, said Pavan Devanahalli, Alstom’s project director for Sydney Metro.

“The Hong Kong South Island Line project was similar in terms of technology and architecture and the fact that with MTR as the operator, they were very familiar with the system and the technology. It really made sense for us to use that same platform.”

With the expertise for Sydney’s Metro North West Line drawn from Hong Kong, Singapore, and elsewhere Alstom set about adapting the system for the local conditions while building a base of local expertise.

As Devanahalli highlights, although the technology is proven, making it a success in a new context produces challenges.

“When deploying CBTC in a new environment, the challenge is the system might be mature, but you’ve got to make that work in the context of the operational conditions. The operator is new and Australia is doing this for the first time, so it was about adapting and integrating that technology.”

Alstom not only worked with the operator but also construction and civil contractors in the building of a new maintenance facility at Tallawong, the new railway from Epping to Tallawong and the retrofitting of the existing Epping to Chatswood line. Devanahalli points out that doing this while ensuring that the project was completed on time and under budget required working in parallel to optimise delivery.

“When you look at what was accomplished in the brownfield section, which was from Epping to Chatswood, that was done very quickly and there were significant lessons learnt in not only how to convert or upgrade to a new line but also in terms of the coordination of activities between ourselves and other contractors, including infrastructure works,” said Devanahalli, who expects these lessons to be applied and processes amplified in the conversion of the Sydenham to Bankstown section from suburban rail to metro.

In this section of the project, which will extend the Urbalis system from Chatswood, via new underground tunnels beneath the Sydney CBD and onto Sydenham and Bankstown, the existing train line will be upgraded. In this case, focusing on minimising disruption and maximising coordination for efficient access has led Alstom to hand-pick key talent to ensure the project is completed smoothly.

SETTING A BENCHMARK FOR OPERATIONS
While Sydneysiders have enjoyed the frictionless Metro North West Line, Alstom has been optimising the software behind the services to enable the growth of the system’s capacity. Being a digital system, Devanahalli highlights that the signalling team have been working with the operator to bed down the system through a series of software upgrades to enable greater efficiencies.

“What we’ve done during the course of the last year is optimise the software to meet the operational needs of MTS. We have had not only our international expertise pool available but also we have our local expertise that can react quite quickly to any new need or operational requirements.”

On the first day of operations, headways between trains were set at five minutes, however the intention was always to reduce that to four minutes once the system was in place.

“The timetable changed from five to four minutes between trains and all of that was done seamlessly. Of course, there was quite a bit of machinery moving in the back end but what that meant is that we could support the vision of Sydney Metro” said Devanahalli.

Even with all of the complexities that come with an entirely new train system, after a year the system has achieved figures of 98 per cent system reliability, and 99 per cent train availability. Devanahalli puts this down to the work of the entire array of partners who came together on the project.

GETTING THE LOCALS ON BOARD
Although Alstom initially brought in its expertise from projects in Asia as well as Europe, throughout the delivery of the new driverless line the company has built up a local talent pool for the next stages of City and Southwest.

“They went through a rigorous process over two years of going through the design and commissioning, and they’ve now been deployed in the operations centre, warranty and maintenance programs so they can now experience what it means to be in the operations and maintenance side of a project,” said Devanahalli. “The talent has been strategically groomed over the last three years and in-between the two projects they’ve been sent to Melbourne and Singapore for ongoing technical training, leadership, and professional development.”

Having some of the most advanced signalling projects occurring around the world in Australia right now has created a motivation for new signalling engineers to deliver the current generation of digital signalling.

“CBTC is really about software,” said Devanahalli. “But, on these projects, installation is key. Having a partnership and collaborative approach to delivering these projects is absolutely essential in Australia. No one person is delivering a project.”

Having built up a base of local expertise in the delivery of software-based signalling projects will enable future improvements to the system that allow for flexibility as demand shifts and changes.

Overall, Devanahalli highlights that the experience Alstom has had on Sydney Metro, as well as other projects around the globe, is that when it comes to signalling, it is not the product that is important, but the outcome that the signalling system can provide – safety, customer satisfaction, reliability and availability.

“The beauty of the CBTC system is that it’s interfacing with almost everything that happens on the railway, so there’s not a single system that it doesn’t touch – except maybe the station elevator. It’s really a matter of identifying the right technology and being able to interface that to CBTC. From that point forward the CBTC software does its magic.”
