Metrorail on Tuesday said CCTV cameras will be installed at railway lines countrywide by March next year.
The project which will cost around R700 million, aims to curb vandalism.
In the Western Cape, the rail operator is finalising an additional project that will result in more cameras being erected along Cape Town's central railway line.
Metrorail's regional manager Mthuthuzeli Swartz said the Cape project which will help protect equipment along the line and will cost about R51 million.
Earlier this year, Metrorail employed 100 National Defence Force reservists to beef-up security measures.
Swartz said with the spike in recent incidents of vandalism and theft, more security was desperately needed.
