Oxford Bus Company is the trading name of The City of Oxford Motor Services Ltd. It is a bus operator serving the city and surrounding area of Oxford, England. It is a subsidiary of the Go-Ahead Group. History Horse trams and horse buses The City of Oxford and District Tramway Company served Oxford with horse-drawn trams from 1881. By 1898 its network served Abingdon Road, Banbury Road, Cowley Road, Walton Street and both and railway stations. Horse bus services developed to complement the tramway network. By the early 20th century both Iffley Road and Woodstock Road were horse bus routes. On Saturdays only there were horse buses from Headington to the city centre and from Cowley village to the tram terminus in Cowley Road. In 1906 the City of Oxford Electric Traction Company took over from the City of Oxford and District Tramway Company. It planned to electrify and expand the network, but was defeated by local opposition. Motor buses In 1913–14, and under threat of competition from William Morris and Frank Gray, the tram company replaced its trams and horse buses with Daimler motor buses. In 1921, the company was renamed City of Oxford Motor Services Limited (COMS). It continued to expand its operations into the surrounding countryside. From the 1930s, COMS was controlled by British Electric Traction, with the Great Western Railway having a minority shareholding. The fleet livery was red with maroon and pale green relief. Most of its buses were built on AEC chassis and running gear. Numerous former COMS buses have been preserved, including a large and notable collection at the Oxford Bus Museum in Long Hanborough in Oxfordshire. In 1969 COMS became a subsidiary of the National Bus Company. Greater integration of city and country services began. In 1971, the Oxford – London coach operator South Midland, which had been controlled by the neighbouring Thames Valley Traction company, was transferred to COMS and the fleet name for the entire operation became Oxford South Midland. An acute problem for the operator was the competition for staff with Morris Motors, whose Cowley factory was near the Oxford garage. One response was to move to one person operation of buses in the 1970s. After some trials, the Oxford company established the city's pioneering park and ride bus services in 1978. The London express service began in the same year. In 1983, COMS was split into separate Oxford
