Central Scottish Omnibuses Ltd was a bus operating subsidiary of the Scottish Transport Group formed in June 1985 from Central SMT Company Ltd, and operated until July 1989 when it was merged with Kelvin Scottish to form Kelvin Central Buses.
From its head office in Traction House, Motherwell, Central Scottish had an operating area covering the whole of Lanarkshire, bounded by Glasgow to the west, Airdrie to the north, Strathaven to the south and Shotts to the east.
Central was the largest operator in central Scotland and was responsible for local and interurban services in the towns of East Kilbride, Airdrie, Motherwell, Wishaw and Hamilton. Depots were also located in these towns.
Central Scottish also provided coaches for Scottish Citylink work, mainly from Glasgow and central Scotland to other points in Scotland.
The Scottish Motor Traction (SMT) Company was founded in Edinburgh in 1905, and expanded rapidly. After the First World War, this expansion included the acquisition of bus companies operating in other parts of Scotland. In 1928 SMT was purchased by the London, Midland and Scottish Railway (LMS) and the London and North Eastern Railway, and became the parent company for railway-owned bus operations in Scotland. Central SMT was a product of this series of acquisitions and mergers.
