Turnback will allow high frequency services on Fremantle and Airport lines
The first kilometre of track has been laid between Redcliffe and Airport Central stations.
Tunnel fit-out is an essential part of the project and includes installation of rail infrastructure and electrical, mechanical, hydraulic, safety and communications systems.
The transformational METRONET Forrestfield-Airport Link project has reached another major milestone, with tracklaying in the eight-kilometre tunnels now underway.
Earlier this year we asked residents and businesses within the City of Kalamunda to choose their preferred name for the new line's terminus station.
