METRONET - High Capacity Signalling

Prospective pipeline

Greenfield (construction) or brownfield (government asset divestment) projects needed or likely to occur within the next five years, but is not formally proposed by a state, territory or major local government.

Credibly proposed

The project or divestment is supported by a state, territory or major local government, is subject to studies or other processes (such as pre-feasibility or scoping studies or business case development), and is likely to proceed to formal announcement.   


The project has a firm commitment and timeline from a state, territory or major local government, but has not yet entered the market.

Under procurement

The project or transaction is under procurement (such as a call for Expressions of Interest, requests for tender, or another offer to the market).

Preferred bidder announced

A preferred bidder has been selected and is in exclusive negotiations.

Recently closed

Projects that have progressed to contractual close remain on ANZIP for 12 months.

ANZIP is focused only on major infrastructure activity, above the following thresholds:


Construction projects: > AUD$300m

Investable greenfield & brownfield: > AUD$100m

New Zealand

All greenfield and brownfield projects and divestments: > NZD $100 million


STATUS: Announced
JURISDICTION: WA, Commonwealth
TYPE: Greenfield

Project Scope

The High Capacity Signalling project will upgrade the existing signalling and control systems, which are nearing the end of their asset lives, to an integrated high-capacity signalling system, the rail network will have capacity to grow and see more reliable, safe and punctual train operations.

Infrastructure Australia's business case evaluation determined the preferred option for the project would include new signalling technology and Communications-Based Train Control. The business case recommends the implementation of an Automatic Train Control system using modern, radio-based, high-capacity Communications-Based Train Control technology on all three line-groups of the Perth metropolitan railway network.


Key Dates
2021: Construction expected to commence
2030: Expected completion




Federal Government: The 2020-21 Federal Budget allocated $227 million to METRONET for High Capacity Signalling and the Morley-Ellenbrook Line projects, however, it is unclear how this funding will be divided.



Project History

April 2020:Infrastructure Australia's Business Case Evaluation identified the following options for the High Capacity Signalling project:

  • Option 1 – Asset life extension with moderate signalling modifications (Base Case)
  • Option 3 – Asset life extension with conversion from existing three-aspect signalling to fouraspect signalling
  • Option 4E – New signalling technology / European Train Control System (ETCS) Level 2
  • Option 4F – New signalling technology / ETCS Level 2+ with Automatic Train Operation
  • Option 4B – New signalling technology / Communications-Based Train Control; and
  • Option 4J – New signalling technology only on those sections of the network requiring high capacity signalling and maintaining legacy signalling in sections of the network where high capacity signalling is not required.


Option 4B was the preferred option.
