R.J. (Ron) Buckley's photographs show the changing locomotive scene taking place throughout the counties of Northumberland, Durham and Yorkshire, illustrating from the later 1930s those pre-grouping classes that were still working. These included the work of such well known designers as Wilson Wordsell and Vincent Raven of the North Eastern railway, John Aspinall of the Lancashire and Yorkshire railway and Samuel Johnson and Henry Fowler of the Midland Railway. Ron's later photographs, from 1946 onwards, continue to show remaining working pre-grouping locomotives and also portray the newer designs of William Stanier, Charles Fairburn, Edward Thompson and Arthur Peppercorn, as well as standard examples designed under Robert Riddles.
