As an employee of British Rail, Michael Patterson spent much of the Thatcher era recording the nation's railway stations from Edinburgh to Ipswich and everywhere in between.
Starting in 1979, Michael was employed by the state-owned rail firm's heritage watchdog with a view to enhancing the passenger experience and thereby improving public relations.
Included in his fascinating archive, which Michael has made available on Flickr, are a series of priceless images of Edinburgh's two main terminals: Waverley and Haymarket.
