Thornlie-Cockburn Link

Thornlie-Cockburn Link


The Thornlie-Cockburn Link will be Perth’s first cross line connection, making travel around the city by train more flexible and providing a higher level of public transport service to Perth’s southern suburbs.

Connecting the Mandurah and Armadale lines will open up new opportunities for longer-term developments around the future Nicholson Road and Ranford Road stations.

The Thornlie-Cockburn Link will support growth and accessibility across the southern suburbs by providing direct access to employment, sporting and recreation opportunities at Canning Vale, Cannington Strategic Metropolitan Centre, Burswood Peninsula and the eastern Central Business District.  


Work is expected to begin in late-2019.

Construction

NEWest Alliance, made up of CPB Contractors and Downer, have been announced as the preferred alliance to construct the project. The Alliance will now work closely with the Public Transport Authority to progress the designs and construction schedule once the contract is signed next month.

It is expected the Thornlie-Cockburn Link will generate around 1680 jobs. These will include construction works and supply chain contractors. Any WA Government roles associated with the project will be advertised on the WA Jobs Board.

Environment

While the Thornlie-Cockburn Link is located in existing rail corridors, a number of important environmental concerns will continue to be considered.  

Flora management
The existing rail corridor has been largely cleared of native vegetation and is maintained as an active freight rail corridor.
However, some clearing will be needed for the Thornlie-Cockburn Link, which will require approval under the Environmental Protection Act 1986.  

Fauna management
During construction, any areas marked for clearing will be inspected for animals to be relocated beforehand. Relocation by an appropriately qualified  specialist will be timed, where practicable, to prevent coinciding with the main nesting/breeding season of fauna species – usually spring and summer.

Noise, vibration and light
Investigation and planning is underway to ensure introducing the passenger lines means noise and vibration levels are no worse, and where possible are better, than existing levels experienced by the community.

Predicting noise and vibration is a complex science that takes a number of inputs to create a comprehensive model for the project. For this project, the inputs included:
  • onsite noise monitoring results conducted  in June 2017;
  • noise monitoring  of similar noise sources;
  • data on existing soil conditions and structures (buildings, bridges, walls) in the project area; and
  • early rail design.
Based on early designs, an initial operational noise and vibration assessment has recommended noise walls in certain locations and anti-vibration ballast matting under both the freight and passenger lines.

This will continue to be reviewed and updated as the designs progress once a contractor is appointed.

Lighting for the shared path and station areas will be directed away from residential properties as much as possible and will be assessed during the final design stages.

Aboriginal heritage
Duplicating the rail bridge over the Canning River will occur within an Aboriginal heritage site.

While the project impact is expected to be minimal, recognising the importance of this site to the Whadjuk people, relevant approvals have been sought. Specialist Aboriginal people  will also be engaged to monitor the  initial ground work to further ensure there are no heritage sites or artefacts disturbed  within these areas.

Community

Community Reference Groups

The Thornlie-Cockburn Link Community Reference Groups (CRGs) consists of local residents and businesses to help the project team identify local opportunities, issues and concerns.

The role of the CRGs is to act as a sounding board regarding the delivery and impacts of the project throughout the construction phase. The CRGs will bring feedback or collect community enquiries for discussion in the meetings to identify any issues.

Given the breadth of the Thornlie-Cockburn Link, and the density of surrounding residential areas, two zones were identified and CRGs were formed for each - an east and west CRG zone either side of Nicholson Road. Formed in July 2019, the CRGs represent a range of demographics, locations, interest, opinions and experience.

Thornlie-Cockburn Link CRG West members are:

Alec Frith, Christine Hulley, Curtis Mckinley, Kathy Pritchard, Patricia Skinner, Robert Stanton, Scott Kivelhan, Senthilatiban Vembaiyan, Todd Wood and Zaaren Dhanbhoora.

The minutes of each meeting will be published below.

Thornlie-Cockburn Link CRG East members are:

Amanda McCormack, Anoop Kumar Malaviya, Derek Muttitt, Ernest Nnadigwe, Kelly Ibbitson, Kirsty Connell, Kishin Bhavnan, Molly Tebo, Rebecca Druce and Veronica Ye.

The minutes of each meeting will be published below.

Project Update

Place Making

While transport projects can be planned and delivered in a relatively defined timeframe, the associated development around a station can take longer and is often not within the State Government’s control.

For the Thornlie-Cockburn Link, the METRONET Office will continue to work with state agencies, local governments and the private sector to help transition the areas around Nicholson Road, Ranford Road and Thornlie stations into mixed-use centres.

 
  • General Project

  • How long will construction take?

    We are aiming to meet the Government’s preferred completion date of 2021. The schedule will be developed by the Alliance when it is appointed in late-2019.

  • Will the Thornlie-Cockburn Link be opened in sections or all at once?

    The Thornlie-Cockburn Link will open all at once, which allows flexibility for the Alliance and is its preferred construction methodology.

  • How will construction traffic be managed?

    We are working towards keeping construction impacts to a minimum. There will be construction vehicles in the area during construction, but the impact on the traffic conditions will be minimal.

  • How will you manage people parking on residential streets instead of station car parks?

    Managing street parking is the responsibility of the local authority and outside of the Public Transport Authority’s control. We will raise these concerns with the relevant local authorities.

  • How many parking bays will be installed at the stations?

    Current designs include about 400 parking bays at Ranford Road Station and about 1,000 parking bays at Nicholson Road Station. Ranford Road Station car park will be designed in such a way to allow for future expansion as demand for parking at the station increases.

  • What changes to the bus services will there be in the future?

    Some bus services will be redirected from Thornlie Station to the new Nicholson Road Station and a new route will be introduced linking Nicholson Road Station with Maddington Station. Given the location along an existing high-frequency bus corridor, all passing services will be diverted into Ranford Road Station, with a number of services extended to and some lower demand services truncated and terminated at the station.

    Final service details will be determined 12-18 months before operations. This will follow detailed planning and community consultation to develop a bus network which best aligns with local development and community needs.

  • Why build the Thornlie-Cockburn Link?

    The Thornlie-Cockburn Link area includes a mix of established and developing suburbs that are experiencing significant population growth due to the availability of urban zoned land and continuing demand for affordable land, particularly from young families. South of the Thornlie-Cockburn Link is an 80.8 km2 area which currently has poor public transport services, but is estimated to grow significantly in the future.

  • What is new in the project definition plan?

    The options analysis work completed during the business case phase, established the preferred solution for the projects.

    Since then, the METRONET Office with its partner agencies and stakeholders, have completed early engineering designs, environmental and ground analysis, land use planning to inform transport infrastructure design, construction requirements and other modelling.

    The result is a more detailed scope for the project, which will be used during procurement to select a contractor to deliver the work.

  • What modelling was done to estimate the patronage?

    Extensive modelling was undertaken to estimate patronage using data sources including passenger numbers, population growth, housing density and other demographic information. Modelling was conducted through a Department of Planning, Lands and Heritage tool, the Strategic Transport Estimation Model (STEM).

  • What trains will use the Thornlie-Cockburn Link?

    All platforms will be built to a length of 150 metres accommodate six-car trains for future use. However, the four-car A-series or three-car B-series train sets will be able to meet passenger demand for day one of operations.

  • Will this provide a special event service from Mandurah to Stadium Station?

    Yes, this project allows for a future Mandurah special event service to Stadium Station.

  • Can we change the names of Nicholson Road and Ranford Road stations?

    At this stage the station names are working project names, based on their locations. The names are subject to approval from the Geographic Naming Committee, closer to project completion.

  • Is the project fully funded?

    A combined budget of $1.056 billion has been allocated to the Thornlie-Cockburn Link and Yanchep Rail Extension as a joint funding arrangement with $700 million from the Commonwealth Government and $356 million from the WA Government.

  • When will works begin?

    Works are expected to begin in late 2019.

  • What employment opportunities will this project provide?

    It is expected the Thornlie-Cockburn Link will generate around 1,680 jobs. These will include construction works and supply chain contractors. Any WA Government roles associated with the project will be advertised on the WA Jobs Board.

  • Land use development

  • What land development opportunities are there around the new stations?

    In the short term, the Thornlie-Cockburn Link’s new station precincts at Nicholson Road and Ranford Road will principally support access to the new rail service, including parking and bus transfer facilities, as well as improved cycle and pedestrian links to surrounding residential and employment areas.

    In the medium-to-long term, the stations will be a catalyst for change in their immediate vicinity, encouraging the transformation of underutilised urban and industrial land into new transit-oriented developments.

  • Who is responsible for these land developments?

    The METRONET Office will continue to work with key stakeholders, including local government, in guiding any land planning and development to ensure the benefits of investing in good public transport are realised.

  • How will the Thornlie-Cockburn Link affect property values in the area?

    Typically when passenger rail is introduced, property values have improved.  Better transport connections have the potential to lift property values directly but they also benefit indirectly because METRONET’s integrated planning approach enables denser development, leading to more amenities such as shops and health facilities. However, it is too early at this stage to forecast how this project will impact the local area.

  • Nicholson Road Station

  • How will passengers access Nicholson Road Station?

    The station will be accessed from Canna Drive, between the Willow Pond Reception Centre and the police station.

  • Will the local road network be upgraded as part of the project?

    Some roads that approach the station will be upgraded as part of this project. Changes to the network outside of the immediate project area will be managed by the local government. When appointed, the Alliance will assess the local road network, including the Nicholson Road, Garden Street and Yale Road roundabout. Details will be provided as the project progresses.

  • What pedestrian/cycling connections will there be?

    When appointed, the Alliance will work with the local council to assess the path network and determine safe connections for pedestrians and cyclists. Details will be provided as they progress.

  • Will Nicholson Road Station connect to the Canning Vale area to the north?

    The Nicholson Road Station design allows for future connection to development north of the rail corridor, which can be developed as demand increases. The area around the station, such as the passenger car park, may also be subject to change to support future developments.

  • What security measures will be put in place at Nicholson Road Station?

    Nicholson Road Station will be fitted with security measures that are standard at all PTA stations. This includes CCTV, lighting and clear sight lines throughout the area. In the future as development occurs around the station, passive security will also increase with the increase in activity in the area.

  • Ranford Road Station

  • How will passengers access Ranford Road Station?

    Ranford Road Station will be accessed from a precinct entry road, off the proposed Jandakot Airport Eastern Link Road to the south-east of the station.

  • What are the traffic impacts associated with Ranford Road Station?

    Every attempt will be made to limit traffic impacts on Ranford Road. When appointed, the Alliance will assess the local road network and work with the local council to determine what, if any, changes are required to the local road network. Details will be provided as the project progresses.

  • What security measures will be put in place at Nicholson Road Station?

    Ranford Road Station will be fitted with security measures that are standard at all PTA stations. This includes CCTV, lighting and clear sight lines throughout the area. In the future as development occurs around the station, passive security will also increase with the increase in activity in the area.

  • Environment

  • What are the Thornlie-Cockburn Link’s environmental and heritage considerations?

    Environmental and heritage considerations are a key priority for the Thornlie-Cockburn Link.

    Investigations and surveys undertaken by specialist consultants have identified the following environmental and heritage considerations:

    •     Clearing of native vegetation
    •     Loss of fauna habitat
    •     Disturbance of acid sulfate soils
    •     Dewatering
    •     Existing soil and groundwater contamination
    •     Noise and vibration
    •     Aboriginal heritage
    •     Waste management

    These will be monitored and managed accordingly by the Alliance and in consultation with the governing and regulatory authorities.

  • Has the project received environmental approval?

    The Thornlie-Cockburn Link proposal is in the final stage of the environmental approvals process, with the Environmental Protection Authority recently publishing its Report and Recommendations, which was opened for public appeal in August 2019.

    The Public Transport Authority has also been working with key local environmental groups, such as the Urban Bushland Council and Friends of Ken Hurst Park.

  • How will impacts to Aboriginal heritage be managed?

    We recognise the importance of Aboriginal heritage and a METRONET Aboriginal Engagement Strategy has been developed. Initial studies for the Thornlie-Cockburn Link identified that works, specific to duplicating the rail bridge over the Canning River, will occur within a registered Aboriginal heritage site.

    Although the project impact to the Canning River is expected to be minimal, recognising the importance of this site to the Whadjuk land owners, the PTA sought the relevant approvals for the proposed works. Aboriginal monitoring personnel will be engaged to monitor initial ground works to ensure any culturally significant material if uncovered is managed appropriately.

  • What has been done to minimise the amount of land being cleared for the Thornlie-Cockburn Link?

    The original development envelope of the Thornlie-Cockburn Link was reviewed to minimise the amount of vegetation clearing. For example:

    • Initially around 11 hectares of the Banksia Woodland was to be cleared and through engineering reviews this was reduced to around 3 hectares;
    • Initially around 41 hectares of Carnaby’s Black Cockatoo foraging habitat and 176 potential habitat trees were to be cleared and this was reduced to around 23 hectares of foraging habitat and 48 potential habitat trees; and
    • Caladenia Grove Wetland Reserve was avoided.

  • Will replanting will take place after construction is completed?

    Yes. Where possible, replanting of areas with fast-growing small native shrubs and trees will occur following construction. Replanting will be limited within the rail reserve due to visibility and rail safety rules.

    Larger or more mature trees are generally not replanted due to a lower success rate of uptake. To ensure the best chance for survival, the planting will be mostly of smaller, fast-growing native plants that will reach mature heights in a short timeframe.

    Rehabilitation of the impacted Canning River banks will be undertaken with input sought from the local environmental community groups.

  • How will vegetation clearing and animal relocation be managed during construction?

    The existing rail corridor has been largely cleared of native vegetation and is maintained as an active freight rail corridor. However, some clearing will be required for the Thornlie-Cockburn Link, which requires approval under the Environmental Protection Act 1986.

    Prior to vegetation clearing, all areas will undergo fauna trapping by a licenced contractor, with any captured fauna relocated to a suitable location advised by the Department of Biodiversity, Conservation and Attractions.

  • How will noise and vibration be managed during construction?

    The appointed Alliance will prepare and implement a Construction Noise and Vibration Management Plan, in accordance with the Environmental Protection (Noise) Regulations 1997.  The management plan will detail how potential noise and vibration impacts will be minimised. When construction commences, there will be dedicated information available for affected areas, and those impacted will receive advance notice of works.

  • How will noise and vibration be managed when the lines become operational?

    An initial operational noise and vibration management plan has been prepared by the PTA, which has recommended a combination of up to four-metre high noise walls in certain locations and anti-vibration ballast matting under both the freight and passenger lines. The appointed Alliance will comply with the management plan of which will continue to be reviewed and updated as the designs progress.

  • How will impact to my property be managed during construction?

    Once appointed, the Alliance will complete relevant management plans to minimise impacts to nearby properties. Nearby property owners will also be invited to be part of a pre-condition survey. This will form part of managing any damage that may occur during construction.
