africa does not have many cities with rapid transit. among those that have one, the oldest is in cairo, egypt (cairo metro), in use since 1987. some cities in south africa, though, have commuter rail networks with trains that come at high frequencies like rapid transit. australia was the last continent to have a rapid transit system, although its biggest cities already have large commuter rail networks, some of which run in tunnels like rapid transit. the first ever rapid transit system in australia opened in sydney (sydney metro) in 2019. it also uses driverless trains.
