Overview
- High-speed automated testing on the Sydenham–Bankstown section is expected to begin within weeks after low-speed trials commenced in April.
- Transport for NSW is working to a September 2026 opening target, though the premier declined to commit to a date beyond saying it is expected next year.
- The start of operations depends on the national rail safety regulator granting final approval following successful testing.
- Replacement buses continue to carry tens of thousands of commuters daily, with contracts in place through the end of 2026 if required.
- Complex conversion work, including 170 mechanical gap fillers and a dispute with Fire and Rescue NSW over platform hydrants, has added to delays.
