Covering industrial steam throughout the British Isles over several decades, the terrific photographs featured here, captured by David Letcher, document a period of our industrial development that is now long gone. Steam-powered workhorses helped turn Britain into an industrial powerhouse, and these wonderful photographs show these locomotives in a variety of settings - a long way from the steam heritage railways of today. Published for the first time here in a selection curated by transport author Stephen Heginbotham, the photographs offer a richly rewarding and nostalgic tribute to the final years of steam on our industrial railways.
