Yonge, Mark: - Mark Yonge, spent most of his working life in the agrochemical industry and latterly was involved in weed control, particularly on railways. With the advent of strict environmental legislation, he won a top Railtrack Award for innovation with his design for a rail mounted spraying vehicle which fitted with GPS navigation, prevented the contamination of water courses. As a keen historian, he supported the Kent & East Railway, once as chairman and was a founder member of the Rother Valley Railway. His written work indicates a fascination for railways that were never completed and the complex historic affairs of this fascinating industry.
