I can see both sides to the preservation arguments. 1) The City of Birmingham locomotive, which is now at The Think Tank in Birmingham, represents one of 3 Coronation Class LMS locomotives in existence. Thanks to Billy Butlin (of Butlin's holiday camp fame), Duchess of Hamilton and Duchess of Sutherland were originally purchased by him for viewing at his holiday camps (I forget which). Since then, they have been acquired by diffrent groups and undergone several restorations. Duchess of Hamilton is now in the care of the National Railway museum, York and has been cosmetically restored to its original streamlined condition. Duchess of Sutherland, I believe, is being used on the main lines for special trains. City of Birmingham, in my opinion, should be returned to main line condition and used, as mentioned by another contributor, on special trains in and around Birmingham, the West Midlands and beyond. However, as pointed out by Think Tank, this locomotive is in "withdrawn from British Railways" condition and on static display. Full restoration of this locomotive would result in it being stripped down to basics and rebuilt in "almost as new" condition, rendering old parts of the locomotive to the scrapyard. I rest my case(s).
