  • Run a reduced schedule between Mandurah and Aubin Grove stations.

Detour options

  • Level Crossing Closure (5 October 2020 - mid 2022)

    The level crossing at Elliot Place and Cameron Street, Thornlie will be closed until mid-2022 to allow for construction of a new footbridge and ongoing work in the rail corridor.

    There will be no pedestrian access across the rail during this period. Traffic management and detours will be in place, so please allow additional travel time. Access will be maintained to nearby properties.

    Construction of the new footbridge will start from mid-2021 and is expected to be complete by mid-2022.
