Two consortia have also been shortlisted for a contract to design and construct a new three-platform station between Helena and Cale streets, with a 12-stop bus interchange and a 600-bay multi-storey car park, to replace the existing 52-year-old Midland station. The contract also includes the decommissioning and demolition of the old station. The two consortia are: 

  • Transform Midland Alliance, comprising Downer EDI Works and SMEC Australia, and 
  • Midland Junction Alliance of McConnell Dowell Constructors, Georgiou Group, Arcadis Australia, and BG&E. 

All contracts, jointly funded by the federal and Western Australian governments, will be awarded later this year.
