$100M digital upgrade to deliver more frequent trains for Eastern Sydney

Contracts worth around $100 million will deliver important upgrades to Sydney’s rail network between Erskineville and Bondi Junction, on the T4 Eastern Suburbs line.

The new digital system upgrade will allow trains to run more frequently and ensure a faster network recovery after incidents.

New South Wales Minister for Transport and Roads Andrew Constance said the upgrade will mean signalling information is directly transmitted into the train cab, removing the need for drivers to rely on fixed “traffic light” signals outside the train.

“While traditional signals have served Sydney well for many decades, they are fixed at set locations and limit the railway from operating at its full potential,” Mr Constance said.

“The installation of digital signalling will mean when an incident happens, the network can recover more quickly with reduced delays, which is great news for customers.”

“The new technology allows continual electronic communication between the track and train, ensuring network controllers can build in extra network capacity. Trains can therefore safely run closer together and, once installed across the network, additional services will be able to meet projected future demand.”

Member for Vaucluse Gabrielle Upton said the upgrades would deliver more frequent services for train customers in the Eastern Suburbs.

“This mulit-million dollar investment today ensures our train network can cope with the increasing demands of the future, especially on the busy Eastern Suburbs line.”

Construction between Erskineville and Bondi Junction will begin later this year, with the new system expected to be begin operations in early 2024.

The works are part of the Transport for NSW’s Digital Systems Program that will progressively replace legacy signalling and train control technologies with modern, internationally proven, intelligent systems to boost safety, capacity and reliability on the network.

Earlier this year, the NSW Government signed contracts worth around $110 million to deliver digital signalling on the T4 Sutherland to Cronulla line.
