Pierson & Dorman Long wanted to build a steelworks at Richborough Port, with new towns to house the workers at Woodnesborough and Ash and using coal from its colliery at Betteshanger. It regarded the EKLR as a nuisance, and never encouraged it. However, the EKLR did ship coal for export from Snowdown from 1929 to the mid thirties, and pit props in the other direction. All plans were abandoned at the Depression. A main line link for coal traffic was actually authorised for Dover Eastern Harbour via a tunnel under the castle in 1933, just about the time when it was finally realized that the Kent coalfield was a commercial failure.
