Colombo has an extensive public transport system based on buses. The bus service is operated both by private and government own Sri Lanka Transport Board (SLTB). Train transport within the city is limited since most trains are meant for transport to and from the city rather than within the city and are often overcrowded. However the Central Bus Stand and Fort Railway Station functions as the islands primary hub for bus and rail transport respectively. Other means of transport includes auto rickshaws (commonly called "three wheelers" in Sri Lanka) and taxicabs. Three wheelers are entirely operated by individuals and hardly regulated whilst cab services are run by private companies and are metered.
Bandaranaike International Airport serves the city for all International flights while the Ratmalana Airport serves all local flights.
