The system is based on a fibre-optic telecommunications network with audio frequency track circuits used for train detection at stations and balises at other locations on the 926km route.

RAI says the project took 31 months to implement and commissioning was completed on August 23. ATC has been installed at 50 stations on the route, and RAI has installed onboard equipment on 50 GM locomotives, 30 Siemens locomotives, and 10 Siemens Pardis DMUs.

RAI expects to complete the programme to install ATC at 461 stations across the network by next year.
