In 1948 British Rail came into being and with it a new era in railway history. The glory days of steam were numbered and when railway photographers like author Wrenford Thatcher were eagerly snapping their favorite locomotives in the 1950s and 1960s, British Rail were busily introducing many diverse diesel locomotive designs as part of the program to eliminate steam traction. Wrenford Thatcher?s collection of evocative photographs is divided into eastern, southern, western, and midland regions, revealing the changes occurring on the London railways in the post-war years. From Euston and Paddington right out to the suburbs all around London, these stunning, previously unpublished images beautifully record the last great days of steam.
