The Class Y14 was designed by T.W. Worsdell for both freight and passenger duties - a veritable 'maid of all work'. Introduced in July 1883, they were so successful that all the succeeding Locomotive Superintendents continued to build new batches up until 1913 with little design change, the final total being 289.[1] During World War I, 43 of the engines served in France and Belgium.[2]
