Son of an engine driver, Les Summers spent nearly a decade in the Royal Navy before beginning a career spanning 30 years as a professional teacher of history, and as a pastoral head, undertaking research into the conduct of dissident pupils. On retiring from teaching he was able to fully embrace his life-long interest in railways, becoming a transformational editor of the Great Western Society’s Echo magazine in 2009. His first railway article was published over 40 years ago and since 1990 he has contributed regularly to railway magazines, sometimes controversial and often revealing articles, in particular, about locomotive design.
