Hopes for improved punctuality on Victorian public transport

With an in-principle agreement signed between the Rail Tram and Bus Union and Yarra Trams, there are hopes that tram punctuality in Melbourne will improve, following a below target result in February.

Yarra Trams recorded a punctuality rate of 81.5 per cent, with major disruptions due to industrial action occurring on February 17 and 20. This met the punctuality target of 79 per cent, however a reliability figure of 96.2 per cent fell below the 98 per cent target.

Other factors impacting on the result included a derailment of a Route 12 tram on Saturday, February 1, and a truck bringing down overhead wires on Swan Street on Friday, February 28, which impacted Route 70 trams.

The in-principle agreement between Yarra Trams and the RTBU will contribute towards improvements in punctuality in the coming months, highlighted Victorian Department of Transport head of transport services Jeroen Weimar.

“It’s pleasing the parties have come to an agreement that will end any further disruptions for our tram passengers.”

Other transport operators also had lower than targeted results. V/Line services had a punctuality result of 86.8 per cent and a reliability result of 88.8 per cent. V/Line has a target of 96 per cent reliability and 92 per cent punctuality.

Events affecting this result included the train derailment at Wallan on Thursday, February 20. This led to trains on the Seymour, Shepparton, and Albury lines being suspended while investigation and repair works were underway.

“All parties worked together in the wake of the tragedy to support the recovery and investigation and ensure the line could reopen once certified for passenger services to return,” said Weimar.

Bright spots for the regional operator included the Gippsland and Warrnambool lines, which experienced a boost to punctuality and reliability of roughly six per cent, the largest improvement on the regional network.

Metro Trains had a positive month, by delivering 98.6 per cent of scheduled services, above its 98.5 per cent target. Punctuality just fell short of the 92 per cent target at 90.3 per cent.

During February, heavy rain, track and signal faults and police operations disrupted the network.

“We continue to work with Metro Trains to ensure punctuality improves in line with what passengers expect from our metropolitan network,” said Weimar.

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.

MELBOURNE METRO

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.

Rail body advocates for separate airport line between Sunshine and CBD

Rail industry advocacy body, Rail Futures, has criticised the Victorian government’s plan to run the Melbourne Airport Rail Link to the city via Melbourne Metro.

The body called upon the Victorian government to build additional tracks between the CBD and Sunshine, where the airport link will join the existing Melbourne rail network. This would benefit both regional Victoria services and trains to Melbourne’s west.

Rail Futures estimates that soon after the new lines are open in 2025, the new Melbourne Metro (MM) train lines will reach capacity, potentially as early as 2030.

“Notwithstanding this, the State Government appears intent on allocating 25 per cent of MM track capacity between the CBD and Sunshine to Melbourne Airport trains,” said Rail Futures president John Hearsch.

To accommodate demand from trains from the airport, western Melbourne and regional Victoria, the number of trains running at peak times on the Sunbury/Watergardens, Melton, and Ballarat lines.

“Once added to the metropolitan network, the Airport line will remain part of it for a very long time. This is bad news for these communities, long denied adequate train services but promised major service improvements once MM is completed.”

Rail Futures is advocating for a separate rail line, similar to the one proposed by IFM Investors, as part of the AirRail consortium.

“The alternative, long promoted by Rail Futures, is an additional express track pair between Southern Cross and Sunshine, supplementing MM and the Regional Rail Link track pair opened in 2015, already operating at near its designed capacity,” said Hearsch.

Population growth in western Melbourne and Geelong is already placing strain on trains travelling from Geelong to Melbourne via Tarneit and Wyndham Vale. Patronage on the line has grown by 131 per cent since 2015.

“Our plan transfers Geelong trains to the new fast tracks between Southern Cross and Sunshine and also provides additional express tracks between Sunshine and Wyndham Vale,” said Hearsch.

“These changes will enable Wyndham Vale to have a full metro-style service and for Geelong to have its long promised fast trains. Without them, Wyndham residents will have a much less frequent service and Geelong commuters will continue to endure slow journeys and chronic overcrowding, as no more trains could be accommodated between the City and Sunshine.”

New rail bridge and station opens part of $3bn investment

Trains are now running over a new rail bridge in Carrum, located in south-east Melbourne.

Carrum station opened on Monday morning following a two-week construction blitz, including laying track and ballast and installing traffic signalling.

Level crossings at Mascot Avenue, Bonbeach, Station Street, and Eel Race Road were removed as part of the project, making the new station boom-gate free.

The new rail bridge now connects to the existing Frankston line. The Victorian Government has invested $3 billion to upgrade the Frankston line on the Metro trains network, including the removal of 18 level crossings and building 12 new stations.

Sonya Kilkenny,  Member for Carrum, said the “dreaded ding” of boom gates will no longer effect the community, making it safer and quieter.

Construction is still continuing on Carrum station. Current access to the new station is through The Station Street level crossing. The main entrance at McLeod Road is set to open later this year.

Carrum station, located in the bayside suburb, has been designed to accommodate coastal weather conditions, with weather protection pods, shelter canopies on the platform and wind screens in entrances.

The station will create a town square at its main entrance, a garden at the southern entrance, and a new foreshore park and beach promenade linking Carrum to the bay.

Jacinta Allan, Victorian minister for Transport infrastructure, said 34 crossings have been removed and 26 new stations have opened part of the level crossing removal project.

“It’s great to see the new Carrum Station bustling with passengers right on schedule,” Allan said.

“We’re not wasting a minute delivering the road and rail projects our city and state needs.”
