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.
The votes are in and more than three quarters of respondents have opted for High Wycombe to become the permanent name for the Forrestfield-Airport Link's terminus station.
