Major Contract

METRONET - High Capacity Signalling

Under Procurement
METRONET - High Capacity Signalling

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 Automatic Train Constrol System (ATC System). The rail network will have capacity to grow and see more reliable and safe train operations.

The scope of this project includes:

  • replacing the existing ‘fixed-block’ signalling system with a ‘moving-block’ Communications Based Train Control system
  • replacing the Automatic Train Protection system
  • implementing Automatic Train Operation, and
  • implementing Automatic Train Supervision and Regulation to replace the existing Train Control System.

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 found to be the preferred option.

A new Public Transport Operations Control Centre (PTOCC), located directly north of the existing Public Transport Centre in East Perth, is expected to include a centralised signalling equipment room, network control floors, and office space to support the High Capacity Signalling project implementation.

Apr 2020 Infrastructure Australia's Business Case Evaluation identified implementing 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.
May 2021 The Federal Government announced $32 million in new funding for the project, bringing its total commitment to $134 million to date.
Sep 2021 The WA government announced an additional $229 million in funding for the project to be spent over the next four years on e Radio Systems Replacement, the Public Transport Operations Control Centre, and the Train Control and Signalling projects.
Sep 2021 The Public Transport Authority opened an Expressions of Interest (EOI) phase for the design, supply, installation, testing, commissioning and maintenance of the proposed for the High-Capacity Signalling project, closing on 11 November. The contract is expected to be awarded in mid-2023. The WA Government also announced ADCO Constructions as the preferred proponent to deliver the PTOCC package of works.
Mar 2022 The 2022-23 Federal Budget allocated an additional $441 million to the METRONET program over four years, including $116 million to the High Capacity Signalling poject.
