Residents in Byford and the wider Serpentine-Jarrahdale area will connect to the Perth CBD on a seamless 42-minute train journey once the Byford Rail Extension is complete.

The Armadale Line will be extended approximately 8km south to a new ground-level station in Byford, supporting one of the fastest growing areas in Australia.

Armadale Station will be rebuilt as an elevated station with three nearby busy level crossings removed and replaced with elevated rail.

Other level crossings between Armadale and Byford will also be removed with alternative treatments to improve traffic flow and ease road congestion.

The remaining two lanes on the Thomas Road Over Rail Bridge opened recently, which means traffic is now flowing in both directions across the bridge. This significant milestone will make it easier and safer for commuters to cross the Armadale Line.

The project will kick-start development opportunities in the Armadale and Byford town centres, providing new and safe connections around the stations.

More detailed project information can be found via the METRONET Byford Rail Extension page.
