Aimed at the 3-7 age group, this innovative book applies the Haynes treatment to one of the most popular children's characters. Inspired by the world-famous Haynes manuals, this book explains how Thomas works, how his driver operates him, and how the engineers of the Sodor railway keep him in tip-top condition. Some of Thomas's friends also feature, with Henry's overhaul, for example, offering the chance for young readers to see how a steam engine is taken apart and refitted. This brightly designed book will delight children and parents alike.
