The Gautrain railway network links the two main cities (Pretoria, Johannesburg) and the OR Tambo airport in South Africa via an 80 km track serving ten railway stations, 18 km hereof is underground.

RNS in collaboration with Axell Wireless designed, supplied and implemented a safety radio network in the tunnels and underground stations. To meet the high reliability requirements and safety standards of the project, RNS deployed a radiating cable (Leaky Feeder) system in the tunnels.

The system is interlinked to the remote master control unit and 22 remote station and emergency shaft units via dual fibre optic cable feeds. The system design makes the network fully redundant and guarantees automatic fall-back in case of a fault. The system is flexible, easily extendable and can be adapted to new technologies and standards in the future.
