Perth signalling upgrade added to Infrastructure Priority List

Infrastructure Australia has listed the High Capacity Signalling Project, part of the Metronet program, as a priority project.

Now added to Infrastructure Australia’s Infrastructure Priority List, the move acknowledges the benefits which could come from upgrading signalling on the Perth network.

In addition to extensions to lines and new stations, Metronet is proposing to replace the existing signalling and train control system with new infrastructure. This would lead to improvements across the network, said Romilly Madew, chief executive of Infrastructure Australia.

“Modern Automatic Train Control systems can facilitate a range of service improvements, such as schedule and headway optimisation, turn-up-and-go service frequencies, real-time passenger information, faster recovery from operational disruptions, and better regulation of train traffic at network pinch points.”

The system will use a Communications Based Train Control System (CBTC), and the project’s wider scope covers implementing automation train operation, supervision, and regulation, as well as the construction of a Rail Operations Centre, a back-up signalling equipment room, and upgrades to the current Alternate Train Control facility. Current signalling and control systems are reaching the end of their operational life.

“The High Capacity Signalling project will make better, more efficient use of the existing rail network. The existing signalling and control systems are nearing the end of their asset lives. Upgrading them to an integrated high-capacity signalling system will give Perth’s rail network the capacity to grow while also creating more reliable, safe and punctual train operations. Coupling this project with Metronet new lines and stations will create a more attractive public transport network for Perth residents,” said PTA spokesman, David Hynes.

Madew said the project aligns with the priorities of Infrastructure Australia.

“It’s important to note that the High Capacity Signalling Project strongly aligns with Infrastructure Australia’s own recommendations to improve the performance of urban rail networks in our capital cities by making better use of existing networks and technology.”

Implementing the signalling project would enable capacity increases of up to 150 per cent on the rail network and the business case submitted by the WA Public Transport Authority found a cost benefit ratio of 2.6.

The business case stated that a single contractor will design, build, and maintain the Automatic Train Control system, and that the first roll out would be either on the North-South line group by 2026 or the South-East line group also by 2026.

Minister for Population, Cities and Urban Infrastructure Alan Tudge said that the signalling upgrades will fit alongside other improvements to the network also designated significant by Infrastructure Australia.

“For people in the north of Perth the Morley-Ellenbrook Line will be 21 kms of rail line improving connectivity and productivity for locals,” said Tudge.

“At the same time the Capacity Signalling System project will improve the performance of the current rail network by allowing trains to run more often, reliably and safely.

“Metronet will get cars off the road, bust congestion, connect communities to jobs and services and unlock opportunities for business growth in the region.”
