This study at Crewe Works shows only too clearly the complexities of the Caprotti Valve Gear as fitted to 'Standard 5' 73125. The tasks of shed and works fitters are key to the smooth running of locomotives and detailed knowledge of the various components are essential. The Caprotti gear was invented in 1921 by Arturo Caprotti of Italy. Photo taken Sunday 13th October 1963.
