Author Geoffrey Lloyd continues this series of pocket books exploring Wales's railway heritage, each revealing one of the nation's 'lost lines'. The Heads of The Valleys line served the communities of Merthyr, Tredegar and Abergavenny dating back to 1860, linking the area to major population centres around south Wales and the rest of the UK on a dramatic route of curves, steep gradients, tunnels and viaducts. The line was finally closed in 1958. The history and social background of the railway and its passengers during this period is explored station by station and brought vividly to life through extensive research and archive photography, some of which has never been published before. AUTHOR: Geoffrey Lloyd worked in the gas industry for over 35 years and spent over twenty years as an officer in the Royal Air Force Volunteer Reserve. Taking early retirement, he then embarked on an academic career in pursuit of educational qualifications that took him to Doctoral level and travelled the world as a consultant and conference speaker. He spent several years with Voluntary Service Overseas that took him to locations such as Sri Lanka and Sierra Leone. He has always harboured a deep interest in railways from childhood and wrote his first book for Graffeg in their 'Lost Lines Series' in 2018. He has written ten other books on various subjects such as the History of the Institution of Gas Engineers and Managers and research methodology books. He was born in south Wales and now lives in Mid Wales.
