Terence is a hard-working caterpillar tractor that works near Thomas' Branch Line.
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!
Terence was seen ploughing in a field by the Skarloey Railway.
Terence can nowadays be seen working along the trackside ploughing fields in different parts of Sodor.
Terence was seen in the field by the Skarloey Railway with a shepherd when Duncan derailed and crashed into the stage of the Sodor Shakespeare Company.
Terence is kind and calm, always willing to help a friend.
