Sydney’s much-anticipated Southwest Metro is moving closer to completion, with extensive testing now well underway and more than half of the required trial work already successfully completed. The major infrastructure project is set to transform connectivity across southwest Sydney, bringing faster and more frequent services to thousands of commuters.
Testing is currently being carried out for up to 22 hours a day, across most days of the week, reflecting the scale and complexity of the project. More than 55 per cent of the required testing checks have already been completed, with further system integration and acceptance tests scheduled in the coming months.
This phase of testing focuses on ensuring all systems operate seamlessly together – including trains, signalling, platform screen doors and station technologies. Key operational elements such as the synchronised opening of train doors and platform systems are being carefully validated to ensure a safe and reliable passenger experience from day one.
Once operational, the metro line connecting Bankstown and Sydenham is expected to deliver high-frequency services, with trains running every four minutes during peak hours. The system will be capable of moving up to 18,000 passengers per hour in the morning peak, significantly boosting capacity across Sydney’s rail network.
The project is also set to deliver notable travel time improvements. Commuters travelling from Marrickville to Gadigal will save up to 12 minutes, while journeys from Lakemba to Victoria Cross could be reduced by as much as 24 minutes. These gains are expected to reshape daily travel and improve access to key employment and education hubs.
Construction progress is also advancing steadily, with station upgrades nearing completion and key precincts such as Bankstown Plaza and Dulwich Hill Plaza already opened. Overall, conversion works across the corridor are approximately 85 per cent complete, marking another significant milestone in the project timeline.
Transport Minister John Graham described the current phase as a critical step in integrating all elements of the new railway, while local leaders highlighted the long-term benefits for communities, including improved access to jobs, education and lifestyle opportunities.
The Southwest Metro is part of a broader transformation of Sydney’s rail network, with future upgrades expected to increase train capacity into the CBD from around 120 services per hour to up to 200. This expansion is aimed at supporting the city’s growing population and improving network efficiency.
While temporary closures and disruptions have been required to complete integration works, authorities have acknowledged the patience of local communities. With testing progressing rapidly and key milestones being achieved, the project is now firmly on track for opening in the second half of the year.
