Edward Thompson was the London & North Eastern Railways second Chief Mechanical Engineer, following the death of Sir Nigel Gresley in 1941.

He was in office from 1941-1946, when he retired, after a long career as a mechanical engineer, working for several railway companies, including the North Eastern, Great Northern and after the grouping the London & North Eastern Railway.

He was a very controversial figure, often maligned by railway historians for his reconstruction of several classes of steam locomotive, including the Gresley prototype pacific Great Northern, which many people still feel was unnessasery.

However there is more to Edward Thompson then his period as Chief Mechanical Engineer of the London & North Eastern Railway, in that he had a complex side to him, which might of originated from his experiances in the First World War, during which he served with distinction in France.

This book for the first time, sets out to explain both the man and his philosophy, looking at the complex reasoning behind the way he came to his decisions over locomotive design and why he decided to reconstruct a number of Sir Nigel Gresley's locomotives.
