From TrainSpottingWorld, for Rail fans everywhere
Clarence Reginald Dalby (1904–1983), born in Leicester, England, was the third illustrator of the Railway Series by W.V. Awdry.
History
He illustrates books The Three Railway Engines (re-illustrated) to Percy the Small Engine.
Although Dalby's illustrations didn't entirely satisfy the author, and errors in detail caused all kinds of problems, his pictures—with their bold lines, lively energy and bright, gem-like colours—quickly caught the imagination of young readers and he undoubtedly set the style for the series.

Dalby died, aged 79, in 1983.
