We should be looking to upgrade rail link to Prestwick Airport

The Herald - ESURRECTING the idea of a Glasgow centre to Glasgow Airport rail link is about as sensible as the Edinburgh trams fiasco ("Airport rail link could still go ahead, says Yousaf", The Herald, November 20), and Letters, November 20, 21 mp; 22). While the monorail sounds a much better solution, an upgraded rail link between Glasgow centre to Prestwick Airport would seem like a much more sensible and cheaper option.
