In 2010, a larger network was proposed, but ultimately canceled due to government funding and executive leadership turnover. In 2019 a much smaller project has been proposed, due to be completed in 2022; it will consist of 18 stations mainly linking coastal areas to the island's airport. Luanda is the capital of Angola, while also its largest city. Luanda is the economic, political, and cultural center of Angola. Luanda has two different forms of urban rail transit currently. Currently part of Luanda's eastern suburbs are served by regular commuter rail, that runs along existing rail infrastructure. Much of the network was damaged extensively during the Angolan Civil War so service is not as extensive as it could be, but a Chinese firm is contracted to continue the railway repairs. A light-rail project is envisioned for Luanda proper, currently the project just passed feasibility studies in 2019. This project will complement the existing rail lines and connect more areas of Angola to Luanda, with a network of approximately 149 km of rail lines. Funding for the project is unclear, but the government assures the financing has been secured at US$3 billion this is one of the more expensive light-rail projects on the continent. In February 2020, the government signed a public-private partnership agreement with Siemens Mobility to begin the construction of the light-rail network. "see: Metrorail (South Africa)"  South Africa has the most extensive urban rail network on the continent. Transnet is the national company that oversees all modes of transport, any railways in South Africa operate under that umbrella organization. Urban rail or Metrorail is specifically underneath the Passenger Rail Agency of South Africa or PRASA. Metrorail is a national system with a total of 478 stations, this system though is divided into four different regions. All major regions of the country have some form of Metrorail, for example the Gauteng Metrorail region corresponds to the Gauteng province. This province is home to Johannesburg and Pretoria, which are the different capitals of the South African state. Cape Town and other metro regions also have their respective Metrorail systems. Although Metrorail has extensive experience operating the network, in recent years it has come under the attack due to protests, labor strikes, and looting.
