The original Thomas the Tank Engine series, by Reverend W. Awdry, is a rare but impressive set of stories for young children: it includes moral lessons, complexity of character and distinctive and deep use of language. (Unfortunately, these are not captured in the more recent books spawned by the popular franchise.) The original series uses an assortment of transportation machinery (engines, buses, tractors, trucks, carriages, etc.) to bring to life various personality types and temperaments. The engines, mirroring the maturity-level of young boys, have adventures, learn about their own weaknesses, face the consequences of their decisions, and grow in character.
