Futureproofing Perth’s public transport network

Perth’s public transport network is being set up for generations to come with long-term major technology and infrastructure upgrades that will allow for more trains to run more often. A $1.6 billion contract has been awarded to the AD Alliance, consisting of Alstom and DT Infrastructure Pty Ltd, to design, supply and build the METRONET High Capacity Signalling Project.

The project will support the record investment in the transformational METRONET program, with the number of trains running on the network expected to grow significantly in coming years.

Works will include:

• upgrading signalling along the total length of the Transperth train network (500km)
•  installing more than 7,000 transponders enabling precise train location
• introducing new in-cab signalling equipment for 125 trains including Transwa regional trains
• improving passenger information on more than 600 displays on 89 stations across the network
• installing more than 250km of electrical conduit.

The project will be delivered in stages over the next decade to minimise disruptions to train operations.

How does high capacity signalling work?

The system uses what is known as a ‘moving block’ system. The network creates and continuously monitors an exclusive space or ‘block’ around the train, automatically preventing other trains and their blocks from overlapping. This means trains can safely run closer together – using 30 or 40 per cent less space than the existing system – with an assurance that there is sufficient space and time to adjust speed or safely stop in any circumstance.

The METRONET High Capacity Signalling Project will replace the current rail network’s ageing signalling and control systems introduced in 1990. Control technology will be housed at the new state-of-the-art Public Transport Operations Control Centre in East Perth.
