English Electric produced a wide variety of products ranging from the Lightning interceptor jet to everyday consumer electronics, but in the railway world the company is best known for its classic British Rail diesels built in the late 1950s and the 1960s. The most powerful examples of these were the English Electric Type 4 (BR Class 40), the English Electric Type 4 Co-Co (BR Class 50) and most famously the English Electric Type 5 (BR Class 55 'Deltic'). In the post-steam age these large diesels have won a place in the hearts of a new generation of railway enthusiasts and today there is a thriving diesel preservation movement with many examples operating across the UK. Martin Hart began photographing diesels in the late-1970s and since then has built up an exceptional portfolio of stunning railway images. A collection of the surviving examples of all three types of these photogenic English Electrics are shown in this publication both in fully working order as well as those still under long-term restoration.
