The Railway Children is a childrens book originally serialised in The London Magazine during 1905 and first published in book form in 1906. It has been adapted for the screen several times, of which the 1970 film version is the best known. The Oxford Dictionary of National Biography credits Oswald Barron, who had a deep affection for Nesbit, with having provided the plot. The setting is thought to be inspired by Ediths walks to Chelsfield railway station close to where she lived, and her observance of the construction of the railway cutting and tunnel between Chelsfield and Knockholt.
