In the Province of the City of Havana, provincial transport authority functions are carried out by 11 divisions. 4. The Havana public bus transport is managed by two divisions, Omnibus Metropolitanos (OM) and MetroBus. The Omnibus Metropolitanos division has one of the most used and largest urban bus fleets in the country. Its fleet is diverse with old donated and new bus models operating on the bus transport network. The fleet consists primarily of well-used Busscar Urbanuss (manufactured in Russia and the Republic of China) and includes the infamous camellos (camels), which are truck trailers ill-fitted for passenger transportation.
