Metrorail is an operator of commuter rail services in the major urban areas of South Africa. It is a division of the Passenger Rail Agency of South Africa (PRASA), a state-owned enterprise which is responsible for most passenger rail services in South Africa. The Metrorail system consists of 471 stations, 2,228 kilometres (1,384 mi) of track, and carries an average of 1.7 million passengers per weekday.
Metrorail was formed as a business unit of Transnet and was transferred to the South African Rail Commuter Corporation (SARCC), the predecessor of PRASA. In the early 1990s Metrorail was placed under Spoornet, another business unit of Transnet but on 1 January 1997, Metrorail became an independent business within Transnet and the Metrorail regions were formed. In 2006 Metrorail was transferred back into the SARCC; in 2008 the SARCC became PRASA.
Because Metrorail operates services in several separate cities, for operational purposes it is subdivided into four regions.
Previously there were two regions: Witwatersrand in the south and Tshwane in the north. The southern area covers the Greater Johannesburg Metropolitan Area (also known as the Witwatersrand). Trains run from Johannesburg and Germiston outwards to Springs, Pretoria, Soweto and Randfontein via Krugersdorp.
The northern part covers Pretoria and surrounding suburbs. Trains run from Pretoria station outwards to the various suburbs of the city, as well as southwards to Johannesburg via Kempton Park and Germiston stations (in the Witwatersrand region).
