Terence is a hard-working caterpillar engine.
Terence met Thomas the Tank Engine while ploughing one autumn by the Branch Line. He introduced himself, only to be greatly discriminated by the proud blue tank engine! Terence was rather offended, but he carried on with his work. Later on, Thomas refused to wear his snow plough that winter, and banged it until it broke! He carried on his journey, but got stuck in a deep valley snowdrift! Terence the Tractor came to his rescue and the two made up their quarrel, showing that everyone is special in their own way and that everyone is truly really useful!
