ATSB releases preliminary report into Wallan train derailment

The Australian Transport Safety Bureau (ATSB) has released the preliminary report into the Wallan train derailment.

Although the report does not contain findings, the report does note that signals at Wallan were reversed, causing the XPT train to enter a passing loop at a speed of more than 100km/h when the speed limit for entering the loop was 15km/h, and exiting the loop was 35km/h.

“Earlier that afternoon, the points at either end of the Wallan loop had been changed from their ‘Normal’ position to their ‘Reverse’ position, which meant that rail traffic, in both directions, would be diverted from the Main Line into the loop track,” said ATSB chief commissioner, Greg Hood.

“A Train Notice reflected this change and also specified a 15 km/h speed limit for entry into the loop.”

Prior to the derailment, the XPT service had travelled through a section from Kilmore East that was being managed using an alternative safeworking system. During this section, an accompanying qualified worker (AQW) boarded the lead power car and joined the driver at the head of the train. Before proceeding, the driver and the network control officer communicated via radio about the train authority for the section to Donnybrook.

After passing Kilmore East, the train sped up to 130km/h, the line speed for this section. Then, the train travelled to Wallan and was diverted onto the Wallan Loop, the points for which had earlier been changed from Normal to Reverse.

The emergency brake was applied a short distance before the points, which slowed the train a small amount, however the train entered the turnout travelling at above 100km/h, leading the train to derail.

The alternative safeworking system was implemented on the section of track from Kilmore East to Donnybrook due to damage to the signalling infrastructure, caused by a fire on February 3, 2020.

Investigations into the incident are ongoing, and are being led by Victoria’s Chief Investigator, Transport Safety (CTIS), along with the New South Wales Office of Transport Safety Investigations (OTSI). The Office of the National Rail Safety Regulator is also continuing to investigate.

CEO of the ARTC, John Fullerton, said that the ARTC would learn from the incident.

“Accidents of this nature are complex and can hardly ever be attributed to just one cause, and this investigation is one important way of ensuring lessons are learned, and systems and processes are put in place to avoid something similar from happening again.”

The derailment killed the driver, John Kennedy, and the AQW, Sam Meintanis.

“ARTC joins with all in the rail industry in again extending our sincere condolences to the families, friends and colleagues of John and Sam,” said Fullerton.

“The main focus of all in the rail industry – whether it is rail network operators like ARTC, the passenger and freight rail customers who use it, or the many rail contractors – is to operate safely.”

A Transport for NSW spokesperson noted the report.

“We continue to engage with the investigators on what is a complex set of circumstances that led to the loss of a NSW TrainLink employee and a contracted ARTC staff member,” said the spokesperson.

“Our thoughts are with the families and friends of those who lost their lives in this accident and we await the final report by the ATSB due in 2021.”

Hood noted that the full investigation could take over 18 months to complete.

“However, should any safety critical information be discovered at any time during the investigation, we will immediately notify operators and regulators, and make that publicly known.”

Further investigation by the ATSB will inquire into the derailment sequence, track condition, rollingstock condition, crew and passenger survivability, train operation, and management of train operations. So far, the investigation has not found a fault with the rollingstock or the track itself that directly contributed to the derailment.

PTA Radio Systems Replacement project falls victim to US-China trade war

The consortium delivering the digital radio systems project in Perth has fallen apart.

An alliance of Huawei Australia and UGL (HUGL) won the contract to upgrade radio communications for Western Australia’s Public Transport Authority (PTA) in 2018, however on March 27, 2020 WA Minister for Transport Rita Saffioti announced that the current contract will no longer proceed.

The HUGL consortium fell victim to increasing trade restrictions placed on Chinese exports by the US government, with restrictions imposed in August 2019 cited by the WA government as the tipping point.

In 2017, the WA government announced the $120 million project, which would involve installing new towers and poles with digital-friendly infrastructure, to enable the replacement of the current analogue radio system with a digital one. This involved all radio devices in trains, security vehicles, and handheld radios. Moving to a digital system would allow for data as well as audio to be transmitted by radio. Future Automatic Train Control systems, which PTA has aimed to install as part of the Metronet project, would utilise the digital radio systems.

Since the contract was awarded, the parties have had to grapple with restrictions placed trade between the US and China. Tariffs imposed on Chinese exports would increase the uncertainty around the cost of the project, timelines, and effectiveness of the final solution.

“It is extremely unfortunate that the State Government’s project – which is limited to a radio network for train drivers and transit guards – has been caught up in the ongoing trade dispute between the US and China,” said Saffioti.

The WA government has indicated in a statement that it will continue with the project, although it will be delayed.

“Given the trade dispute, and the current economic and health crisis facing the world, the PTA has recommended a fresh approach for the radio replacement project,” said Saffioti.

“The PTA will continue its plans to deliver a new digital radio system for our expanding public transport system.”

Potential options include the withdrawal of Huawei Australia from the contract, or the termination of the contract as a whole. The PTA will look to preserve current subcontract arrangements.

The Australian Communications and Media Authority has extended the deadline for the PTA to vacate the analogue radio spectrum to beyond 2021.

The effect of extreme weather on rail and track infrastructure

As severe weather events become more intense and frequent, rail infrastructure owners and mangers are responding to this new reality.

Documenting the risks that climate change poses to the Australian rail sector, the Australasian Railway Association (ARA) listed six types of impacts. These were: track failures due to extreme temperature days, increased risk of flood and storm damage to track infrastructure, sea level rise flooding coastal tracks, yards and other infrastructure, wind damage to overhead lines, track failure due to decreased soil stability and increased erosion, and increased bushfire damage risk.

During the summer of 2019-2020 the rail industry experienced almost all of these impacts.

In New South Wales, bushfires closed multiple major train lines, including the Main Western Line through the Blue Mountains, the Southern Highlands Line between Goulburn and Macarthur and the Unanderra Line between Moss Vale and Unanderra.

Rail infrastructure owners around the country felt a number of these impacts, and Arc Infrastructure, the manager of the WA rail freight network, was no exception.

“This summer we have seen bushfires in the South West, Mid West (Mogumber) and Kalgoorlie/Esperance cause interruptions to rail traffic, heavy rainfall impacting track infrastructure, and an electrical storm in the Mid West affect signalling and communications infrastructure on the Eastern Goldfields Railway,” said an Arc Infrastructure spokesperson.

Sydney Trains also acknowledged how the weather can impact infrastructure.

“Extreme weather events, such as high temperatures, strong winds, lightning, bushfires, high rainfall, and flooding, can have a significant effect on the performance, efficiency and operation of Sydney Trains’ infrastructure,” said a Sydney Trains spokesperson.

With these increasingly severe and frequent weather events recognised as constituting a new normal, rail network managers and infrastructure owners are having to grapple with what this means for their assets.

BUILDING RESILIENCE

In Infrastructure Australia’s Australian Infrastructure Audit 2019, resilience was a key theme. The report acknowledged that although Australia’s extremes have been well known – floods, drought, fires, and cyclones being an almost yearly occurrence – resilience, the capacity to recover quickly from difficulties, was not reflected in planning processes.

Resilience takes a different kind of thinking than had been previously reflected in planning documents. Although methods and protocols to repair damaged infrastructure were established, the data to be able to predict future events was not always available.

“Timely access to evidence that aids the evaluation of likelihood and consequence can help the planning of construction, maintenance and resilience. However, evidence about the scale of risks, their impacts and the costs of addressing them is often weak or not accessible,” write the authors of the report.

In this context, climate change becomes a compounding factor. The modelling of risks is based upon events that have happened in the past. When events start becoming more frequent and outside the historical range of severity, these models have to be re-evaluated.

“In a rapidly changing environment, risks shift in nature and severity, complicating assessment. This can lead to reactive, rather than proactive, responses to both short- and long-term risks to networks,” write Infrastructure Australia.

The report notes that there is much to be done.

“Australia’s infrastructure sector lacks clear, publicly available guidance on how to manage risk and plan for greater resilience in the future.”

THE RAIL INFRASTRUCTURE OF 2100, BUILT NOW
While Infrastructure Australia’s assessment was made for Australia’s infrastructure as a whole, rail itself has some key challenges. Rail networks are expected to last for up to 100 years, with some track in use today laid in the early 20th century.

The longevity of rail infrastructure presents a critical issue, as the cost of relocating infrastructure has been so high as to be prohibitive. However, as noted in Building resilient infrastructure prepared by Deloitte Access Economics for the Australian Business Roundtable for Disaster Resilience & Safer Communities, the increased cost of natural disasters will lead to the replacement of damaged assets becoming equivalent to the entire cost of large infrastructure programs, suggesting that resilience building is a nationally significant infrastructure project on its own.

Within this context, the rail infrastructure being built now has to account for changes expected to occur in the next 100 years. In the best-case scenario of global temperature rise being kept to between 1.5 and 2O°C, sea level rises of up to a metre are predicted. The knock on effects of this on rail track infrastructure have been catalogued by the ARA.

Sea level rise will directly impact low lying sections of track, particularly those freight lines that carry bulk cargo for export. Increases in extreme rainfall, leading to flooding, can cause assets to be inundated and landslides. With sea level rising, coastal and inland areas will be vulnerable to inundation, and increased frequency and severity of heat waves will cause track buckling and brownouts and blackouts.

With these risks in mind, the ARA calls for the industry to look at mitigating risks via a long-term program of activities. Whether collaborative or led by individual organisations, the ARA notes that successful planning will require the embedding of adaptation and continuity into planning, development, maintenance and improvement programs of all major rail infrastructure owners.

Some infrastructure owners are already planning of how to respond to this changed environment.

Sydney Trains, whose network was significantly affected during the summer of 2019-2020, is building resilience into the physical nature of the network.

“In recent years, Sydney Trains has undertaken a number of initiatives to protect the network from weather events. These include replacing timber sleepers with concrete to reduce the likelihood of significant rail head movement, tension- regulated overheard wiring, improved lightning and surge protection at assets like control centres and substations and improving advanced weather warning systems,” said a Sydney Trains spokesperson.

These works are part of a $1.5 billion annual program of routine and periodic maintenance across the network.

In Western Australia, Arc Infrastructure is currently looking into how to build in resilience to its network, as Arc Infrastructure CEO Murray Cook, told Rail Express.

“We have an innovative research project underway across our network to prevent the risk of derailment through the use of research, data and technology, supported by the deep knowledge and experience of our people.”

Arc Infrastructure is currently in the process of building a system to predict, detect, and prevent derailments that occur as a result of track section washaways, said an Arc spokesperson.

“In order to predict washaways, we are using various sources of information (including historical track washaway data, historical rainfall data and topographical data) to understand and quantify the potential damage caused by various intensities of extreme weather across our network. This data is then being correlated with realtime rainfall data to generate alarms for probable washaways on specific sections of track.”

So far, the project is being tested on historical events, with results showing that of the washaway events that occurred in February 2017, 47 per cent of the locations were predictable, based on the analysis.

Across Australia, a combination of planning, technological innovation, and consistent maintenance will be required to ensure that the rail netowrks laid down today can be used safely and efficiently in 2100.

Bumper year for ARA

Danny Broad shared some parting thoughts to the rail industry about the importance of smart rail technology and the need for young blood.

Outgoing Australasian Railway Association CEO Danny Broad hosted his last AusRAIL as CEO before handing over the reins to incoming CEO Caroline Wilkie.

Broad was elected ARA chair at the 2019 ARA Annual General Meeting (AGM), taking over from Bob Herbert – who will continue his contribution to the rail industry as Chairman of the ARA’s harm prevention charity, TrackSAFE Foundation.

“I thank Bob for his strategic leadership and achievements as chairman of the ARA, specifically the development of a new constitution, leading to improved governance and democracy within the ARA,” Broad said.

As part of his outgoing address, Herbert addressed some of the issues he considered significant to the rail industry.

“Rail is a victim of our federation. There is no one sovereign government calling all the shots for rail like there is for industries like defence or shipbuilding. Make no mistake, this holds rail back, with nine governments to deal with on key national issues,” Herbert said.

“It has stopped rail throughout its history, from the time the first rail tracks were carried. The cause lies in the way our political imperatives play out, it brings a natural cautiousness in decision making. Governments are always in different stages of the election process and rail is disadvantaged as a consequence.”

As an example, Herbert cites the operation of the Transport and Infrastructure Council (TIC).

“This is the forum where transport ministers across the jurisdictions come together twice a year and are supported by a body of senior bureaucrats. Unfortunately, outcomes from this process can only be described as last common denominator.”

As such, he explained how trying to achieve a National Rail Plan is “still illusory”.

“The bureaucrats so often have differing priorities to industry, and they become entrenched within government departments. In some cases, meeting with industry seems to be anathema to them, so progress is at a snail’s pace and this is extremely frustrating for industry.”

In August 2018, members of the ARA met with the council so that companies could present their challenges to the council.

“These were telling representations from our members on challenges relating to skills, resources, and standards,” Herbert said. As a result, the council decided to develop the Rail Action Plan through the National Transport Commission.

“We’ve seen the first cut of this plan and so far, I regret to say, it falls a short of what we would like. So, there’s a lot more argy bargy to be doing with the National Transport Commission.”

However, he warned industry against relying on government to deliver “what we can deliver ourselves”.

As part of his own AusRAIL address, Broad recapped some of the ARA’s activities in what he called “an exciting and demanding year in all sectors of rail”.

The ARA, Broad said, spent 2019 advocating to governments about some of the biggest issues facing the industry.

“We have focused on advocating to governments on how best to address the skills shortage, resulting in the development in the National Rail Action Plan, by the National Transport Commission.”

The ARA has been calling on state, territory and federal governments to commit to a unified pipeline for major rail projects, to allow the private sector to better prepare itself with adequate skills and equipment to ensure contracts are executed as efficiently as possible.

As part of this, the organisation recommended the federal government resource the Australia & New Zealand Infrastructure Pipeline in its 2019-20 Budget Submission.

The ARA lodged seventeen submissions to parliamentary and government inquiries on behalf of the sector over the last year.

One of the key issues for a number of its submissions to government in 2019 included advocating for fairer rules for freight rail operators.

“As far as possible, domestic rail freight markets should operate on an even footing with other modal choices. This requires an environment with equitable regulatory settings to enable competitive neutrality between competing modes of transport,” says the ARA’s annual report 2019.

The ARA also called for an extension of the Inland Rail line, the largest freight rail project in Australia.

“The current project has the Inland Rail line ceasing at Acacia Ridge. The ARA calls for a commensurate project to ensure a freight rail line continues all the way to the Port of Brisbane. Research undertaken by Deloitte shows that building a dedicated freight rail connection to the Port of Brisbane could achieve a 30 per cent rail modal share, which would remove 2.4 million truck movements from the local road network,” according to the annual report.

Among other issues, the ARA also calls for a “pragmatic approach to fast rail that recognises the need to plan for an invest in elements such as modernised signalling systems, passing loops, track duplication, and other critical requirements to increase infrastructure capacity and speed of passenger services”.

“We have been progressing the smart rail and technology agendas, working with industry and governments on improving accessibility, advocating for rail and supporting rail careers through programs such as the women in rail pilot mentoring program and the formation of the young leaders advisory board, a potential attraction and retention campaign and the future leaders program to name just a few,” Broad said.

“I’m very proud of where the ARA is now, and feel it is the right time to pass on the reigns to our new CEO,” Broad concluded.

Doha Metro nears completion

Doha, the capital city of Qatar, is closing in on opening its automated metro network in time for the 2022 FIFA World Cup.

The network is designed to do the heavy lifting for the expected one million visitors who will attend the World Cup, as well as increasing the share of journeys via public transport in Qatar from 0.5 per cent to 21 per cent.

Electrical systems provider Thales is supplying both major elements of the metro system and providing project management services as the interface between civil works providers and electromechanical suppliers.

Thales will supply the train control system – in this case Communications Based Train Control (CBTC) driverless signalling – as well as the Operational Control Centre, passenger information and announcement systems, CCTV, and automatic fare collection.

Sustainability is a core component of the project, both in shifting commuters from cars to metros, and by reducing the network’s consumption of energy.

“The Doha Metro will be a real solution to traffic congestion, and the Metro’s efficient operations will save energy. Furthermore, Thales signalling systems will enable operators to adjust operations depending on consumption of electricity,” said Arnaud Besse, marketing and communications director for Urban Rail Signalling at Thales.

When complete, the metro network will cover 85km via 37 stations. A fleet of 110 fully automated trains will traverse the network, connecting Hamad International Airport, the Old City, and the inner suburbs of Doha.

“The Red Line has already started operating. It will be the longest line, with 18 stations over more than 40 kilometres. The Gold Line, made up of 11 stations, is also in service. Both lines have already enabled the operator to serve commuters and tourists,” said Jean Saupin, general project manager for the Doha Metro.

The last metro station, Legtalifiya Station is expected to open later in 2020, to connect the Metro with the to be finished Lusail Tram.

The four projects shaping Australia and New Zealand

Four “nation shaping” projects are contributing to Australia and New Zealand’s substantial infrastructure pipeline. Their project directors gave overall updates on these major transport projects at AusRAIL PLUS 2019.

CROSS RIVER RAIL

While Queensland has enjoyed significant population growth in recent years, nearly 90 per cent of that growth has occurred within South East Queensland (SEQ). This region is expected to further increase its population by around 1.5 million over the next twenty years.

Cross River Rail will address a major bottleneck within this region. As such, it is Queensland’s highest priority infrastructure investment and the government has allocated $5.4 billion towards the project.

Currently, there is only one inner-city crossing over the Brisbane river and just four inner-city stations. Cross River Rail will unlock the bottleneck by providing a second river crossing, therefore doubling the capacity of the network and allowing more trains to run more often, as well as integrating with roads and bus services to enable a turn-up- and-go public transport system across the whole of SEQ.

The project incorporates a 10km rail line from Dutton Park to Bowen Hills, which includes 5.9 kilometres of twin tunnels under the Brisbane River and the CBD, with four new underground stations. A new European Train Control System (ETCS) signalling system is also being delivered to improve safety and assist in managing capacity constraints in the network. Numerous station upgrades between the Gold Coast and Brisbane and three new stations at the Gold Coast end the network are also planned.

Cross River Rail Authority’s program director David Lynch says early works have now been officially completed, though these are relatively small in the overall scheme and context of the project.

“Our procurement processes are essentially complete as of the end of October, and construction is now underway across all three packages, with four to five years of construction and commissioning ahead,” Lynch said.

“All major work sites have now been handed over to the contractors.”

The mammoth project will be delivered under three major infrastructure
packages of work: the Tunnel, Stations and Development (TSD) public-private partnership (PPP); the Rail, Integration and Systems (RIS) alliance; and the European Train Control System (ETCS).

The TSD PPP will deliver the underground section of the project, including the tunnel from Dutton Park to Normanby and the construction of four new underground stations. It includes the associated mechanical, electrical and safety systems, such as vertical transportation for passengers at underground stations, above and underground track work, tunnel portals and dive structures, traction power systems and rail operation and control infrastructure. The package also includes a property development opportunity above Albert Street station.

It will be delivered by the PULSE consortium.

The RIS “UNITY Alliance” will deliver the design, supply and installation of the supporting rail system, including rail civil and electrical works, rail operation systems and controls, as well as rail signalling and communications work. The alliance will also deliver accessibility upgrades to six suburban stations. The alliance will be responsible for the integration of Cross River Rail into Queensland Rail’s train network.

The ETCS signalling system will be introduced to enable increased capacity
on the network. It will be rolled out over several stages starting with a pilot program on the Shorncliffe Line in 2022 with early works commencing in late 2019. As part of these early works, trains and tracks will be fitted out with ETCS equipment which sends continuous data about the position, direction and speed of trains and enables the system to calculate a safe maximum running speed for each train. The ETCS will be delivered by Hitachi Rail STS.

Cross River Rail is being delivered with the help of Project DNA, the CRRA’s Project Digital Network Approach.

“It is a complete digital twin of the Cross River Rail project. Now, we are currently working in the space of 3D and 4D, but developing additional dimensions as we move forward.”

Lynch explains how the digital twin was developed, “where previously we built separate systems and models, here we’re using a common data environment.”

“Essentially, it is one model with multiple applications to be used by multiple
teams, so whether in the space of project delivery, program controls, communications and engagement or future precinct and planning and delivery, we’re using the one integrated model.”

The model is built in three layers according to Lynch, the first being the Building Information Modeling (BIM) at the core of the model.

“The second layer gives us geographic information system (GIS) mapping, which enables us to move from the 2D into the 3D environment, while the third layer uses the unreal gaming engine to provide an interactive and virtual reality experience.”

The collaborative approach enabled by Project DNA helps in the design, construction, management and operation of the assets built, says Lynch. It will also improve the on- time and on-budget delivery of the project.

The first stage of demolition for the Cross River Rail has commenced and Cross River Rail is now well into the delivery phase. An 85-metre tower crane will be used to bring down three buildings at the Brisbane Transit Centre site. Each building will be demolished level by level, which will take up to a year.

METRONET

A historic lack of investment into public transport resulted in the significant sprawl of Western Australia’s capital city, particularly north-south along the coast. This is why the Metronet initiative, the single largest investment in Perth’s public transport, is about unlocking the latent capacity within the existing network, according to executive director of Infrastructure, Planning and Land Services Owen Thomas.

Thomas says that, ultimately, the initiative will close to triple the capacity of the existing network through targeted investments, including a high capacity signalling system and more trains.

Metronet is the state government’s long- term plan, equally focused on transport infrastructure as on land use outcomes, which will see new communities created as a result of investment. The underpinning target is a 45 per cent increase in dwellings near high frequency transport infrastructure by 2031. As part of delivering against that, the state’s Department of Communities, which largely delivers social housing, is targeting their investment program around specific Metronet sites as part of a social and affordable housing package.

Fundamentally, the initiative involves the creation of 72km of new railway, up to 18 new stations, the removal of eight level crossings, the replacement of the ageing A series rail car fleet and acquisition of an expanded fleet of 246 new C-series railcars, and the optimisation of nearly 5000 hectares of land.

According to Thomas, the most significant and challenging aspect of the project is the implementation of the communications- based train control (CBTC) across the network.

The final business case for the system is currently under consideration. According to Thomas, once it is rolled out, the signalling system will enable more frequent services, every 4 minutes in peak.

Through early works, Thomas says that his transport infrastructure team, working in conjunction with the station precincts development team, have found that it will take $20-$25 million for other enabling infrastructure, such as utilities, to be delivered at the stations.

“We’ll likely see the rail infrastructure delivered within four to five years from the project commencement, but regarding the longer-term outcomes, we will not see many of the station precinct developments on site until up to 15 to 30 years away. So, one of the key challenges is how to incrementally stage those outcomes so that you get the long-term benefits you want but don’t have a sterile station environment from day one.”

In late December, “NEWest Alliance” was awarded a major Metronet contract
for $1.25bn, to deliver the Yanchep Rail Extension and the Thornlie-Cockburn Link. The consortium comprises CPB Contractors and Downer, who will start construction work in mid-2020.

The project will add 17.5 kilometres of rail to connect the Armadale and Mandurah lines through existing stations at Thornlie and Cockburn Central. The new link will include two new stations at Ranford Road and Nicholson Road.

The Thornlie-Cockburn Link will be the first east-west connection between rail lines on the Perth network. It will involve replacing a pedestrian level crossing with a footbridge, duplicating the Canning River Rail Bridge, and modifying the Ranford Road Bridge.

The Yanchep Rail Extension will deliver the last proposed section of the Joondalup Line, from Butler to Yanchep, along a 14.5km route. It will public transport journey times by at least 30 minutes to and from the city.

It’s estimated that by 2031, the Thornlie- Cockburn Link and Yanchep Rail Extensions will serve a population catchment of 400,000 people.

Downer EDI was named as the preferred proponent to build the major rail components at one of Metronet’s level crossing removal projects, at Denny Avenue.

This level crossing removal will be delivered through two design and construction contracts and will include raising more than 800 metres of track and associated infrastructure to enable a new road underpass.

Early works on the project began in 2019 with geotechnical testing, demolition of buildings and removal of a number of Railway Avenue trees. Utility relocation will start in early 2020.

Also in late December, Jacobs was named the preferred proponent to create the business case for the removal of the other six level crossings on the Armadale Line. Preliminary planning identified the potential for more crossings to be included in the project scope.

“[2020] is shaping up to be a defining year for Metronet construction. Perth will have six Metronet projects under construction at once, creating thousands of local jobs and opportunities for local business,” said premier Mark McGowan.

The other major Metronet contract, to deliver the main works for the Morley- Ellenbrook Line, will not be announced until late 2020.

The Morley-Ellenbrook Line will connect the north-eastern suburbs to the broader rail network and is the signature Metronet project. It will include 21km of rail, new stations, two underpasses to allow the rail line to enter and exit the Tonkin Highway median, associated infrastructure to connect to the existing line, road and bridge reconfiguration works and integration across other projects.

Due to the complexity of the Morley- Ellenbrook Line project, the works are divided into four packages, including the Bayswater Station Upgrade (to be awarded in early 2020), the Tonkin Gap project (civil and structural works to allow access in and out of the Tonkin Highway, to be awarded in mid-2020), the forward works and the main works.

The forward works will be delivered under a series of standalone contracts, managed by the PTA and will include geotechnical field investigations, survey works, and the relocation and protection of the in-ground and overhead services of both the PTA and third-party assets.

Main works will be delivered through a competitive alliance contract. It will include the design, construction and commissioning of rail track, systems and five stations. This will include bulk earthworks and retaining, structures, grade separations, roads and drainage.

CITY RAIL LINK

From transferring 14, 000-tonne historic buildings to new foundations to avoiding volcanic lava flows, the Auckland City Rail Link (CRL) project has been one of the more challenging transport infrastructure projects in the Australian/New Zealand pipeline.

Similar to other jurisdictions however, Auckland has had a significant population increase. Since 2010, Auckland’s population has risen by 50 per cent.

“We were at a stage where the road network was unable to cope,” City Rail Link’s CEO, Dr. Sean Sweeney, said.

When a new station was built in 2003, it took until 2014 for the line to be electrified and new rollingstock provided. This resulted in the doubling of patronage numbers.

“That passenger growth has continued ever since and City Rail Link has an ever-increasing need for public transport.”

Construction towards the $4.4bn project officially commenced in 2018 with preliminary works ongoing since 2016. Its scope consists of the construction of twin 3.5 km long double-track rail tunnels underneath Auckland’s city centre, between Britomart Transport Centre and Mount Eden Railway Station.

Two new underground stations will be constructed at Aotea and Karangahape. Britomart will be converted from a terminus station into a through station and Mount Eden Station will be completely rebuilt with four platforms to serve as an interchange between the new CRL line and the existing Western Line. Wider network improvements are also part of the project.

It is slated for completion by 2024.

“Similar to Sydney and Melbourne, we’ve got some form of a loop. The Western line and the Southern line converge at one railway station with the Eastern line, so all of Auckland’s rail traffic goes into the Britomart station and then basically stops there so that the trains get backed up, full or not,” Sweeney said.

“Essentially, what City Rail Link is seeking to do is make Britomart a through station and extend the line back up to the rail network so you can run trains in both directions. Then, by enabling longer, nine car trains, with longer platforms, we can triple the capacity of the rail network.”

This means increasing capacity from 14,000 pph to 54,000 pph into the CBD, allowing for a train every ten minutes in peak.

“By our calculations that’s the equivalent of 16 lanes of traffic into the city centre in peak,” Sweeney said.

This will double the number of people within 30 minutes of NZ’s biggest employment hub, bringing with it significant commercial and residential opportunities around stations.

Though early works commenced in 2016, Sweeney explains that about 10 years ago a forward-thinking Auckland mayor decided to start the project without funding from central government.

“This project had quite an unusual start. The mayor realised that to make Britomart a through station someone had to start building tunnels underneath the city, so Auckland council went out and started construction without central government support which was a very brave thing to do.

“They managed it with a whole range of contracts and multiple contracting types, which made it a little bit confusing but it was what they had to do to get going, and it’s gotten off with different forms of construction, bored tunnels, cut and cover tunnels, etc. There’s a really complex grade separation into existing railway lines.”

One of the challenges for the project is that Auckland is built on volcanoes “some of which erupted as recently as 800 years ago, which is very recent geologically”.

“So, to try and avoid some of the recent lava flows we built an incredibly complex geological model. We used the information that was available to us to plot the safest route. We used this model to locate the top striations, so to avoid some of the most recent lava flows. That was a very complex investigation and we have made that model available to the bidders.”

Another challenge is the current size of the infrastructure pipeline across a number of sectors in Australia and New Zealand.

Over an eighteen-month period, Sweeney tracked the pipeline from $80bn in September 2017 to more than double that in August 2018, and then $220bn in February 2019.

“I’ve never encountered this extent of growth and the way that this complicates what we have to do and the effect it has on our market is a real stretch. Certainly, historically New Zealand has built very little in 20 years and so, even getting major international contractors to take us seriously and come and bid for us was a big piece of work.”

However, early works are now “pretty much completed” according to Sweeney.

Moving forward, the agency has wrapped up the outstanding works – including the remaining tunnels, stations and rail systems infrastructure, as well as the related wider network and tracks – into one contract, Contract 3, to be delivered by a “Grand Alliance”.

The alliance consists of: Downer, AECOM, Tonkin + Taylor, WSP Opus, Soletanche Bachy, and Vinci Construction.

In October 2019, the demolition of thirty empty buildings demolished near the Mt Eden railway station began. This will ensure space for the construction of the southern portal for the City Rail Link’s twin tunnels. The cleared site will be used as a staging area for a Tunnel Boring Machine and other machinery.

The first phase of this demolition is due to be completed in March 2020 , and is being managed by the alliance.

During January, works towards Melbourne’s metro tunnel ramped up with crews working throughout the month to excavate the final section of the tunnel’s entrance and make room for the new track which will connect existing lines to the tunnel.

The crews will complete major concreting works at the tunnel entrance, pouring the final sections of the tunnel roof slab and installing the tunnel support structures.

“It’s now two years since we signed the contract and we’re well up and running at seven construction sites along the alignment,” Tunnel and Stations package director at Rail Projects Victoria, Linda Cantan, said.

As package director Cantan has overseen the procurement and contract negotiation for the $6bn package to build five new underground stations as well as the tunnel itself. She is responsible for managing the contract throughout construction.

A number of companies are building the tunnel, and construction is split across several work packages.

Early works to relocate services and prepare the construction sites were delivered by John Holland KBR. New tunnels and stations are being built through a Public Private Partnership, named the Cross Yarra Partnership consortium which includes: Lendlease Engineering, John Holland, Bouygues Construction and Capella Capital. Yarra Trams will deliver tram infrastructure works.

Rail systems including signalling and systems integration work will be provided
by CPB Contractors and Bombardier Transportation, while a consortium comprising John Holland, CPB Contractors and AECOM will deliver rail infrastructure works including the tunnel portals and realignment of existing rail lines.

The project is projected to be complete by 2025.

“We’re creating is a dedicated rail line between Sunbury and Dandenong. People ask why a dedicated rail line, by taking capacity out of the city loop we free up extensive capacity through the rest of the rail network.”

The Melbourne Metro Rail Project includes twin nine-kilometre rail tunnels between South Kensington and South Yarra and five new underground stations.

The project will take three of the busiest train lines (Cranbourne, Pakenham and Sunbury lines) through a new tunnel under the city and thus free up space in the city loop to run more trains in and out of the suburbs.

“We have 4 tunnel boring machines doing our tunnelling, which were launched from our two logistics sites at North Melbourne and Anzac Station. Meg and Joan are travelling out to the west at the moment.

“Joan has travelled 470 metres out of north Melbourne, and we’ve had to negotiate the city link viaduct under the Mooney Creek. Meg has gone about 137 metres. We’re also travelling along all of the rail network, so extensive work is needed to make sure we’re doing that in a safe way. To date progress has been very good and in fact the grand settlement has been better than predicted.

“On the eastern side of the alignment, we have Millie and Alice who will launch early next year. They’ve been delivered to Domain, beside Anzac station, and will launch in the first half of 2020. They will be heading out to the eastern portal, then be retrieved and brought back to be relaunched and head towards the city.”

“We’re in quite a narrow corridor and have retaining walls to build to ensure that there’s no settlement of the existing tracks, but we’re working in a very tight environment to create those exits and entrances to the tunnel structures. The PPP is constructing a shaft in that area for the TBM retrieval early in 2020.”

“We’re developing these stations for ten car, high capacity metro trains, which will be procured under a separate PPP. As such our construction boxes are about 250 metres long and the width, depending on the station, about 25 to 30 metres,” Cantan explains.

The Eastern tunnel entrance stops beyond South Yarra station as there is not enough room in the corridor.

“What we’re trying to do here is to put another two train lines in a very congested corridor, where we have multiple train lines coming in from the South East.

“This is another area where we have our Rail Infrastructure Alliance working alongside the PPP. The PPP can build their shaft, that will be used for the extraction of the TBM, right next to where the Rail Infrastructure Alliance are doing the cut and cover structure.”

“We’re now underground in a lot of locations so I keep saying to people: be patient with us because we don’t open till 2025, but we’re now underground, tunnelling, excavating and starting the build out of our stations,” Cantan concludes.

Light Rail 2020 agenda to engage with current project pipeline

With one week left until Light Rail 2020, the conference agenda and proceedings are firming up, with light rail projects around the country passing milestones and announcing major components of their delivery.

Newcastle Light Rail recently celebrated its one-year anniversary, after carrying its one millionth passenger in December, 2019. In Sydney, the CBD to Randwick line carried two million passengers in just two months, with the spur to Kensington expected to open in March.

In the ACT, the government has announced that trams will travel along wire free tracks to preserve heritage vistas, and will travel over grassed sections, further committing the project to sustainable outcomes, having already sourced its power from renewable energy.

In Melbourne, an upgraded tram terminus opened to serve the city’s expanding fleet of new vehicles.

With these announcements occurring in the lead up to Light Rail 2020, the conference will be the forum for the discussion of the variety of operational approaches, and the appetite for Australian governments and transit authorities to continue to invest in the transport mode.

Confirmed sessions include seminars on data, integration, and customer service; safety and accessibility; corridor design to reduce collisions; on-board energy storage; and updates on key projects.

ATSB on scene of fatal XPT derailment

Australian Transport Safety Bureau (ATSB) investigators are on the scene of an XPT train derailment north of Melbourne. The derailment claimed the lives of two rail employees and injured several passengers on Thursday evening.

A NSW TrainLink XPT travelling from Sydney to Melbourne derailed near the Hume Freeway at Wallan, roughly 50kms outside of Melbourne, just before 8pm on Thursday evening.

The express passenger train was carrying 153 passengers and five crew at the time of the derailment. Two of those crew members – the driver and the pilot – were killed in the derailment.

Senior ATSB investigators arrived at the scene shortly after 9am Friday morning to commence the formal investigation that will involve Victoria’s Chief Inspector.

Federal and state government officials have confirmed that the ATSB, Work Safe, and the Office of the National Rail Safety Regulator (ONRSR) will conduct a full and thorough investigation to establish the cause of the incident.

Deputy Prime Minister Michael McCormack said no authority in Australia would allow a train to travel on an unsafe track as “the ARTC monitors these things very closely and regularly”.

Michael McCormack said investigations will look at every factor, including examining the speed limit, signalling, track maintenance, and interviewing witnesses.

“The track will not be reopened until everything has been looked at properly by authorities,” he said.

Greg Hood, Chief Commissioner and CEO of ATSB said they will start their investigation straight away once Victoria Police hand over custodian to investigators.

“All evidence will be gathered and examined in the next week or so,” Hood said.

Hood said ATSB will endeavour to release a preliminary report in the next 30 days and a full investigation report will follow.

Victoria Police have confirmed the two fatalities in the crash were the driver, a 54-year-old ACT man, and the train pilot, a 49-year-old Castlemaine woman. Dozens of passengers were taken to Northern and Kilmore hospital for minor injuries following the incident.

Acting inspector Peter Fusinato said the initial investigation will take days and must be completed before the wreckage can be cleared.

The derailment caused the train’s engine and first carriage to be left on their side opposite the track. Both the driver and the worker were in the same area of the train when it came off the tracks.

The standard gauge track is operated by the Australian Rail Track Corporation (ARTC) and has been damaged due to the derailment.

An ARTC spokesperson said services are suspended until further notice, to allow emergency services to respond to a train derailment.

“We are working hard to support emergency services, NSW TrainLink, and investigators to respond to this tragic accident,” the ARTC spokesperson said.

This incident follows a freight train wagon derailment earlier this month in Barnawartha located south of Wodonga, Victoria that caused 1800 damaged sleepers and 180 metres of damaged rail. 

Public Transport Minister Melissa Horne said she had written to the Australian Rail Track Corporation to continue with works on lines in the region after the Barnawartha incident three weeks ago.

“If it’s at all relevant, it will be looked at in the context of this investigation,” Hood said.

James Pinder, V/Line chief executive said the section of track was a “particularly complicated part of the infrastructure” because V/Line trains run alongside XPT trains.

“There are separate signalling systems for the different tracks,” he said.

Pinder confirmed V/Line was operating on the track on Thursday, before the Sydney to Melbourne service derailed.

Paul Toole, NSW minister for regional transport said the government can not speculate what investigations will find.

He said agencies across both Federal and State levels will be working closely together during this situation.

The Victorian Department of Transport said services on the Seymour, Shepparton and Albury lines would be affected by the incident today. The line is expected to remain closed for several days.

Ongoing track fault and delays between Albury and Southern Cross stations had been reported by V/Line’s social media updates in recent days leading up to the incident.

The train left Sydney’s Central Station at 7.40am Thursday morning and was running more than an hour late at the time the accident happened. It was due to arrive at Southern Cross Station in Melbourne at 6.30pm.

Several passengers said the train was gaining speed at the time of the accident after being stopped due to a signalling issue.

One passenger told The Age that signals should have alerted the driver to slow down to be able to move into the side track, but he did not notice the train slowing prior to the derailment.

Four hours before the incident yesterday, the Seymour V/Line Twitter account said the 12:45 Albury to Southern Cross service would be delayed by approximately 70 minutes due to an “ongoing rail equipment fault near Wallan”.

Infrastructure Australia said in December last year that the ARTC’s business case for an upgrade of the Melbourne-Albury North East Rail Line should not be ­included on its national priority list.

The business stated that Victoria’s regional trains had a self-imposed speed limit of 15km/h on the entire line from Melbourne to Seymour, due to “poor track quality” including mud holes and tight rail alignments.

Last year the Victorian and Federal Government committed $235mil to upgrade the North East line, due to be completed by 2021.

The Border Mail reported on Thursday that north-east train travellers were being asked to allow an extra 60 minutes for trips after a signal hut at Wallan was destroyed by fire earlier this month.

Luba Grigorovitch, Rail Tram and Bus Union (RTBU) state secretary said the section of track was awaiting maintenance.

“Conditions were altered and V/Line drivers rightly refused to traverse this section over the past week,” she said.

“The RTBU is deeply saddened by the tragic accident that has taken the life of two rail workers and unnecessarily injured many more.

“Today marks a difficult day for drivers and rail workers across the state and the RTBU will be here not only to offer support but to ensure a thorough investigation is undertaken.”

The union had refused to operate in that area because it believed the tracks were degraded.

Danuek Bowen from the Public Transport Users Association said serious accidents on the Australian rail network are very rare, “but that makes it even more important to investigate the cause”.

Emergency crews, including from CFA and SES, scoured the tracks and surrounding scrub until 10am Friday morning.

Ambulance Victoria stated that an air ambulance was not required at the scene and a number of people did not require treatment. One passenger was taken by road to the Royal Melbourne Hospital in a stable condition.

The front locomotive carriage remains on its side as the train has not been moved from the position where it derailed.

Results from an engineering report will determine when it’s safe to travel trains on the line again.

Toole confirmed that the NSW regional rail fleet of XPT are 38 years old and have served their purpose. The aged fleet will be replaced in 2023 as part of the $2.8b upgrade with  Momentum Trains.

The Express Passenger Train (XPT) travels between Sydney, Melbourne, Brisbane, Dubbo, Grafton and Casino.

Digitalisation key to future of rail

As Transport for NSW (TfNSW) begins work on its new digital systems facility in Chullora, delegates at the Train Control Management Systems conference heard how the installation of digital systems can lead to a rail system fit for the future.

The conference, held on February 20 was opened with a presentation from Joern Schlichting, head of the ETCS programme at Deutsche Bahn, who described how through digitalisation, Germany was building a “fundamentally new rail system”.

In implementing the ETCS programme, Deutsche Bahn will respond to two major challenges the industry is facing, and which are shared by operators in Australia. These are the need to enable the rail network to carry larger volumes of people on existing tracks and overcome the issue of high numbers of staff reaching retirement age. Rather than an end outcome, said Schlichting, “ETCS is a tool in order to think about completely new redesign of the railway system”.

As part of the ETCS migration strategy in Germany, a wholescale digitalisation of the rail network will be undertaken. These include digital interlockings and railway vehicles, and will ultimately provide a platform for the future integration of other technologies, such as automatic operations, and the ability for trains to recognise obstacles and the environment on their own.

“ETCS is not a technology, it is a language,” said Schlichting.

While these technological changes will allow for more frequent and efficient services, the migration to digital platforms is also thought to attract a new generation of rail workers, as many involved in train control reach retirement age.

These are concerns shared by the Australian rail industry, as it adopts ETCS. In NSW, TfNSW is upgrading its infrastructure to ETCS level 2 as part of its Digital Systems project. In Queensland, ETCS will be integrated into the Cross River Rail project.

Sydney Trains seeks suppliers for UPS network

Sydney Trains is searching for suppliers to replace its network of uninterruptible power systems (UPS).

The 40 systems are spread around the network which are a mix of new and aged units.

These systems supply power to the Sydney Trains electrical network, signalling location in particular, in the case of utility power failure. If these systems lost power there would be significant disruption across the train network.

The tender documents outline that a successful tendered will be able to provide installation, commissioning, and maintenance services.

The UPS systems range from 10-25-kVa 1 phase 240V input and output with 110VDC Bus, to 25 and 30kVa 3 phase 415V input and output with 110VDC Bus, and 40kVa 3 phase 415V input and output with either 110VDC or 400VDC Bus.

Tenders close on February 20 at 2pm and can be submitted via NSW’s online tender process.
