Terence is the tractor that works on farms near the North West Railway, sloughing their fields. However, WildNorWester does not have a model for the tractor and is only mentioned in one episode of Sodor: The Early Years.
Terence met Thomas at a field on his branch line sometime between 1925 and 1948. He calls his caterpillar wheels "ugly", but Terence says they are not. Thomas insulted him saying that he will like his own rails for himself. After Thomas was stuck in a snowdrift after refusing not to wear his snow plough, Terence came to his rescue and took both Annie and Clarabel with him first as Thomas' passengers were asked to board the bus home since the delay is going to be much longer. Terence then managed to pull Thomas out of the snow and instead of having ugly wheels, Terence had splendid wheels as said by Thomas.
Terence is a 1934 Caterpillar Model 70, the largest and last design of petrol-powered tractors in Caterpillar's range.
