The $A 6bn tunnels and stations package has gone to the Cross Yarra Partnership (CYP) consortium led by Lendlease Engineering, with John Holland Bouygues Construction and Capella Capital.

A $A 1.1bn systems contract, covering signalling, train and power control systems and operational control systems, has been awarded to the Rail Systems Alliance (RSA) comprising Bombardier, CPB Contractors, Melbourne Metro Rail Authority and Metro Trains Melbourne.

Bombardier will supply its CityFlo 650 communications-based train control system under its $A 310m share of the contract. This will enable trains to operate at 2-3-minute headways.

Early works on the tunnel project are well underway, with major works due to commence in 2018. The project is expected to be completed by 2026.
