During 2006, Stagecoach introduced several new express services, including the short-lived X33 from Ayr to Paisley later extended to Braehead Shopping Centre, of which part of the route from Ayr to Paisley was originally operated by Western until the 1970s, albeit using a slightly different route. The X33 service was the first time the company had strayed into the heartlands of 'Clydeside' Another innovative new service is the X16 connecting Ayr with Hamilton and East Kilbride via Kilmarnock, although as of 2020, the X16 has been cut in half to serve between Ayr and Kilmarnock due to low passenger usage.
