Clydeside Scottish

It was the largest operator in Inverclyde and Renfrewshire and had depots in Rothesay, Largs, Greenock, Johnstone, Inchinnan, Paisley and Thornliebank in the south of Glasgow.

A large number of two-person operated open-platform AEC Routemaster buses were purchased from London Transport for these services, which gave the company the advantage of giving change (as opposed to the exact fare the city operator demanded) without the buses having to linger at bus stops.

Strathclyde Buses retaliated against the competition, however, by introducing routes beyond the city boundary and into Clydeside's operating territory.

Arriva expanded its Scottish operations with the purchase of McGill's Bus Service of Barrhead and Ashton Coaches of Greenock, although the Greenock operations of Arriva Scotland West were later demerged and sold to local management as McGill's Bus Services.
