Based in Renfrewshire, Clydeside Scottish was a member of the Scottish Bus Group and was created from the northern part of Western SMT's area. Covering the Clyde coast from Largs in Ayrshire into Renfrewshire and Glasgow, its distinctive yellow and red buses numbered some 330 on formation of the company in 1985. Soon, the company was operating in Glasgow against Strathclyde Buses, with a fleet of ex-London Routemasters. In 1991, the company became Clydeside 2000, when privatised. Eventually becoming a part of Arriva Buses, the company was disposed of in 2011. The name has gone but Clydeside Scottish left a legacy in the local area, and four buses are currently preserved in the distinctive red and yellow.
