Stagecoach West Scotland  Stagecoach West Scotland is an operating region of Stagecoach UK Bus, comprising Western Buses Ltd based in Ayr, Scotland. Stagecoach West Scotland operates in west central and southwest Scotland, in an area bounded by Greenock and Braehead to the north, Hamilton to the east, Carlisle to the south and the Isle of Arran to the west. Frequent express services also reach Glasgow from throughout Ayrshire. Stagecoach West Scotland operates under five different brands:  In addition, vehicles operating on the former AA Buses services in the Irvine area previously wore the historical AA green and cream livery, though to date there has never been a Stagecoach AA Buses brand. Buses wearing this livery carried simplistic 'Stagecoach' branding. The company also provide vehicles for Scottish Citylink express work, mainly on the Glasgow to Edinburgh corridor. Stagecoach West Scotland had faced sustained competition from the FirstGroup between Ardrossan and Kilmarnock since Stagecoach launched its network of Glasgow city services in the heart of First's Glasgow operating territory in 1997, though First withdrew from Ayrshire in October 2005 leaving Stagecoach the sole dominant operator once again. While minor competition existed for several years from T & E Docherty around Irvine, Stagecoach has since purchased the routes and vehicles used by that operator. Minor competition exists from Shuttle Buses between Irvine and Girdle Toll (including local operation around Kilmarnock and Irvine) along with competition in the Irvine area from Bennetts of Kilwinning, JAS Transport around the Ardrossan, West Kilbride and Largs areas and also McGill's Bus Services between Largs and Greenock. The company has depots in Brodick(Isle of Arran), Ardrossan, Kilmarnock, Ayr, Cumnock, Glasgow, Stranraer, Dumfries. At both the 2005 and 2006 UK Bus Awards, Stagecoach West Scotland took the top award of 'UK Bus Operator of the Year', having narrowly missed out on the prize in 2004. It also received the 'Best Large Fleet Operator' award at the industry ceremony for both years . Stagecoach arrived in the west of Scotland when it purchased Western Scottish Omnibuses Ltd of Kilmarnock for £6m in July 1994. Western Scottish was, at that time, owned by its management and employees, who had purchased the company from the state-owned Scottish Bus Group in October 1991 on the breakup and privatisation of that concern.
