Digital Systems Program
The Digital Systems Program will replace current signalling and train control technology with modern, internationally proven, intelligent systems. It will help improve reliability, increase capacity and enhance customer experience on Sydney’s railways.
Part of More Trains, More Services, 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
- 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 Future Transport 2056, enabling an increase in capacity across the railway network to meet future demand, and improving customer experience by delivering more reliable services, reduced journey times and enhanced real-time information.
Scope, status and key milestones
In 2018, the NSW Government allocated over $800 million towards the first stage of the Program, which involves developing, testing and validating Digital Systems on parts of the T4 Line, from Sutherland to Cronulla and from Bondi Junction to Redfern.
The first major works package has been awarded with Siemens Mobility Pty Ltd (Siemens) to introduce and maintain the Traffic Management System (TMS).
Due to be available for operation in 2023, the TMS will work alongside other systems used by Sydney Trains to control train operations. It continually monitors the position of all trains, helping to keep services running as planned and assists with responses to incidents.
