Project scope

The Digital Systems Program will replace current signalling and train control technology with modern, intelligent systems. It will help improve reliability, increase capacity and enhance customer experience on Sydney’s railways.

Part of More Trains, More Services Stage 2, the Digital Systems Program consists of three main elements:

  • replacing traditional trackside signalling equipment with the latest ‘in cab’ train control technology (European Train Control System Level 2)
  • implementing Automatic Train Operation, which assists drivers – who remain in control – to provide reduced and more consistent journey times, and
  • introducing a Traffic Management System to help the railway recover from any disruption quickly and manage the overall network as effectively as possible.


Digital Systems will help achieve the vision of transport for NSW's Future Transport 2056 agenda, enabling an increase in capacity across the railway network to meet future demand, and provide reduced journey times and enhanced real-time information.

The first stage of the Program involves developing, testing and validating Digital Systems on parts of the T4 Line, from Sutherland to Cronulla and from Bondi Junction to Redfern.


Digital Systems Facility

A new Digital Systems Facility will be built at the existing Chullora Rail Centre to support the integration of future technologies across the Sydney Trains network.

The facility will allow new digital technologies to be tested and integrated in a simulated environment without disruptions to the rail network and provide learning and development areas for staff.

Major construction is scheduled to commence mid-2020. The new facility is expected to be completed in late 2021.
