The Jamaica Omnibus Service (JOS), operated a municipal bus service for the Kingston Metropolitan Area, from 1953 until it was wound up in 1983.
Kingston's first form of public transport was a mule-drawn tram system, which began operating in 1872. In June 1898, the existing mule car service in Kingston was phased out and a transition to electric trams, initially operated by the West India Electric Company, and latterly by the Jamaica Public Service Company. This transition to the electric tram was completed on March 31, 1899. This tram service continued to operate, but the inflexibility of a tram service could not keep pace with a growing city, and the tram service ceased on August 7, 1948.
Kingston's first bus service operated by a company called Jamaica Utilities commenced on August 8, 1948. Initially communities served included, Rockfort, Hagley Park, Mountain View and Three Miles. The service operated by Jamaica Utilities was unsatisfactory, mainly due to the poor condition in which the fleet was maintained. Efforts to get overseas professional advisers was rejected by the House of Representatives as were efforts to get financial support from government.
The government eventually revoked the franchise of Jamaica Utilities, paving the way for the takeover of bus service in Kingston by the Jamaica Omnibus Service (JOS) on December 15, 1953.
The Jamaica Omnibus Service was originally formed by three British companies in 1953: British Electric Traction, Close Brothers, and United Transport. JOS was nationalised by the government of Jamaica in 1974.
The JOS was replaced by a hodgepodge system of private operator owned buses, and franchisees, which provided very unreliable and unstructured services and was very unpopular with the public. In 1998, the Jamaica Urban Transit Company (JUTC) was established and continues operations presently.
The JOS inherited a very dilapidated depot and bus infrastructure from Jamaica Utilities, and the JOS gradually built new facilities, including a depot at Lyndhurst Road and upgraded the existing depot on Industrial Terrace. The JOS also refurbished the existing US built fleet with British built Leyland Engines. By the late 1970s the entire fleet consisted of various models of British built Leyland buses.
At its peak, the JOS had a fleet of over 600 buses, and serviced an area ranging from Spanish Town and Portmore in St. Catherine in the western extremities of the Greater Kingston area, Border, Mt. Charles, Irish Town and Mavis Bank in north rural St. Andrew, Port Royal to the south, and Bull Bay (10 Miles) in east rural St. Andrew.
