Name and Location
PRASA rail signalling system project, South Africa.

Client
Passenger Rail Agency of South Africa (PRASA).

Project Description
PRASA plans to implement a new technologically advanced rail signalling system on its commuter rail network to replace the old and often unreliable system. The company reports that nearly 80% of its existing signalling installations have become obsolete and the remainder are not able to fully support modern and safe railway operations.

The existing system is a mixture of technologies from the 1930s to the 1980s and, in Gauteng, it depends on manual intervention when transferring a train from one control centre to another when the electronic system fails.

The project will include the modernisation of the rail signalling, communications and train management systems in high-volume corridors, such as Naledi, in Soweto, to Johannesburg; Pretoria to Johannesburg; Mabopane to Pretoria; Mamelodi to Pretoria; KwaMashu–Durban–Umlazi; Khayelitsha, Mitchells Plain and Philippi to Cape Town; Kraaifontein–Bellville–Cape Town; and from Simon’s Town to Cape Town.

The new system will enhance operational capacity, allow for better flexibility, improve safety and reduce train delays and reliance on the human factor.

The Gauteng Nerve Centre (GNC) will control all commuter traffic in Gauteng once construction has been completed.

Value
Total value of the signalling programme is estimated at R17-billion.

Siemens has been awarded the R1-billion contract for the Gauteng Phase 1 signalling programme and for the Gauteng Phase 2 signalling programme valued at R2.762-billion.

The KwaZulu-Natal new signalling contract is estimated at R1.4-billion and has been awarded to Bombardier Africa Alliance.

The Thales-Maziya consortium has been awarded the R1.87-billion contract to supply a new signalling solution to the Western Cape.

Duration
The Gauteng signalling project is scheduled for completion in 2018.

The KwaZulu-Natal signalling contract is expected to be completed in 2019 and the Western Cape signaling contract in 2019.
