Using his father's redundancy money, with his sister Ann Gloag and his brother-in-law Robin Gloag he established the Stagecoach Group in 1980, running buses from Dundee to London. Following the deregulation of bus services in Great Britain, expansion continued, and in the late 1980s Stagecoach acquired National Bus Company subsidiaries in Cumberland and Hampshire, and the East Midlands, Ribble, Southdown and United Counties companies. Stagecoach also bought bus operations in Scotland, Newcastle and London, with Manchester being added a few years later. In 1993, Stagecoach was valued at £134 million and was floated on the London Stock Exchange to access capital for new opportunities for buses and trains overseas.
