TransAdelaide’s Centralised Traffic Control & Passenger Information systems have recently been upgraded. The new system was commissioned in June 2006 by United Group Infrastructure, replacing 18 year old equipment that had become prone to failure and difficult to maintain.

This paper describes how, over a 3 year period, system performance requirements were developed into a series of functional specifications which in turn were used as the basis for detailed design work. The paper describes how disparate subsystems were integrated in a network configuration around a central SigView / SigMap core to form a CTC system. And how the CTC system interfaces with the new PI system to provide real-time service information to audio and visual display devices. The paper explores in detail the design of the Automatic Route Setting and Timetable Database facilities developed specially to meet TransAdelaide’s requirements. Finally, it describes how the staged changeover between old and new systems was managed without interruption to rail services.
