The METRONET program represents Perth’s largest ever public transport investment, adding approximately 72 kilometres of new lines and 23 stations to the suburban network to increase capacity.

The Thornlie-Cockburn Link will be Perth’s inaugural east-west crossline, enhancing travel flexibility and improving public transport access to the city’s southeastern suburbs.

Scope of works include

• Services relocation and protection.
• Approximately three kilometres of duplication of railway between Beckenham and Thornlie stations.
• Relocation of freight lines to create space for the electrified passenger railway.
• Approximately 14.5 kilometres of extension to connect Thornlie and Cockburn Central stations.
• Significant modifications at Thornlie to convert it into a through station that accommodates six car trains.
• Cockburn Central to independently service the extension without impacting existing Mandurah Line services.
• Modified grade separations at Karel Avenue and Ranford Road.
• Stations, bus interchanges and parking facilities at Nicholson Road and Ranford Road.
• Noise and vibration mitigation measures.

BG&E carefully considered various factors such as rail freight operations, existing services, stakeholder and other project interfaces, staging of works, and environmental and heritage factors – including obtaining necessary environmental approvals. Additionally, we took into account specific elements like the Beckenham to Thornlie Station operational rail line, crossing the Canning River, the Glen Iris Tunnel and freeway interface, and the Ranford Road bridge.
