Transport

Most Sydney residents travel by car through the system of roads and motorways. The most important trunk routes in the urban area are the nine Metroads, which include the 110 km (68 mi) Sydney Orbital Network. Sydney is also served by train, taxi, bus and ferry networks.

Sydney trains are run by CityRail, a state-run corporation. Trains run as suburban commuter rail services in the outer suburbs, then converge in an underground city loop service in the central business district. In the years following the 2000 Olympics, CityRail's performance declined significantly. In 2005, CityRail introduced a revised timetable and employed more drivers. A large infrastructure project, the Clearways project, is scheduled to be completed by 2010. In 2007 a report found Cityrail performed poorly compared to many metro services from other world cities.

Sydney has one privately operated light rail line, Metro Light Rail, running from Central Station to Lilyfield along a former goods train line. The Metro Monorail runs in a loop around the main shopping district and Darling Harbour. Sydney was once served by an extensive tram network, which was progressively closed in the 1950s and 1960s.

Most parts of the metropolitan area are served by buses, many of which follow the pre-1961 tram routes. In the city and inner suburbs the state-owned Sydney Buses has a monopoly. In the outer suburbs, service is contracted to many private bus companies. Construction of a network of rapid bus transitways in areas not previously well served by public transport began in 1999, and the first of these, the Liverpool-Parramatta Rapid Bus Transitway, opened in February 2003. State government-owned Sydney Ferries runs numerous commuter and tourist ferry services on Sydney Harbour and the Parramatta River.

Sydney Airport, in the suburb of Mascot, is Sydney's main airport, and is one of the oldest continually operated airports in the world. The smaller Bankstown Airport mainly serves private and general aviation. There is a light aviation airfield at Camden. RAAF Base Richmond lies to the north-west of the city.

The question of the need for a Second Sydney Airport has raised much controversy. A 2003 study found that Sydney Airport can manage as Sydney's sole international airport for 20 years, with a significant increase in airport traffic predicted. The resulting expansion of the airport would have a substantial impact on the community, including additional aircraft noise affecting residents. Land has been acquired at Badgerys Creek for a second airport, the site acting as a focal point of political argument.
