Thornlie-Cockburn Link Project Features

Project objectives

The Thornlie-Cockburn Link aims to:
  • provide an improved transport alternative to private vehicle transport in the South Metropolitan Peel sub-region to increase connectivity of the network
  • address public transport service gaps that exist between the existing rail corridors in the South Metropolitan Peel sub-region; and
  • alleviate current and future capacity pressures on the existing rail network and surrounding road network in the South Metropolitan Peel sub-region.


Rail Alignment


trail alignment

The Thornlie-Cockburn Link will be located within the existing rail corridors. Between Thornlie Station and Kwinana Freeway, the passenger rail will be located within the rail freight corridor. To ensure minimal impact to the freight operations, construction will be staged to first relocate the freight lines to the northern end of the corridor. This will make room to build the passenger rail in the southern half.

Along this section of the track, the pedestrian level crossing between Cameron Street and Elliot Place will be replaced with a pedestrian footbridge. With the railways travelling through the existing Ranford Road and Karel Avenue Road bridges, modifications to the bridges will be required to accommodate the extra sets of tracks and meet safety requirements.

The Thornlie-Cockburn Link will travel through the Glen Iris Tunnel, which was constructed as part of Kwinana Freeway upgrades. The extension will come up between the Mandurah Line and will become a single spur just to the north of Cockburn Central Station, where an additional platform will be provided to end the route.

Elliot Place / Cameron Street Footbridge

Works will begin later this year to replace the level crossing at Elliot Place/Cameron Street, Thornlie, with a footbridge. To ensure community safety while work is underway in the rail corridor, the existing pedestrian level crossing will be permanently closed later this year. An early design for the footbridge has been developed with initial concept design based on requirements from both the Public Transport Authority and the freight line operator (Arc Infrastructure). The concept design takes into consideration rail safety, maintenance, accessibility requirements, land boundaries, ground conditions and existing infrastructure. More information about the detours for pedestrians and cyclist will be shared closer to the closure date. Footbridge construction is expected to be completed by mid-2022. See more in our FAQ's. 


Beckenham - Thornlie

Works start at Beckenham Station where the single passenger railway to Thornlie Station will be duplicated. This will also involve duplicating the rail bridge over the Canning River. Thornlie Station was designed and built to accommodate a future extension of the Mandurah Line. Planned works include:

  • separating the linked marginal platforms and extending their length to 150 metres to accommodate six-cars and a ‘through’ rail arrangement;
  • building a new concourse, with lifts, stairs and roof cover between the platforms;
  • modifying the car park to accommodate the platform expansion;
  • removing the existing shared path and installing a new one at the northern edge of the modified western car park;
  • relocating and replacing existing bicycle parking;
  • installing and upgrading station infrastructure, systems, services and amenities to meet current standards; and
  • replacing the existing Western Power substation at the eastern end of the station.

Ranford Road Station

About 29 minutes from Perth by train, Ranford Road Station’s design maximises its location along on a high frequency bus route.

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

Built in a ‘cutting’ about 8.5 metres lower than Ranford Road, the station will include an entry building and concourse connecting to the island platform.

Nicholson Road Station

About 26 minutes from Perth by train, the early design considered how the station will serve passengers on day one of operations, but is future-proofed to support medium to long term residential and employment development in Canning Vale.

Glen Iris Tunnel to Cockburn Central Station

The Thornlie-Cockburn Link will travel through the Glen Iris Tunnel, which was built as part of upgrades to the Kwinana Freeway. The extension will exit the tunnel between the Mandurah Line tracks and become a single spur just to the north of Cockburn Central Station.

Cockburn Central’s existing island platform will be extended 150 metres at the northern (Perth) end to create the terminating platform for the Thornlie-Cockburn Link.

The extended platform will offer at least 50 per cent shelter with an on-platform building to house electrical equipment and staff facilities. Associated services will include security and passenger information systems.
