Terence is an orange crawler tractor who works near Thomas' Branch Line. He is owned by Farmer Finney.


The Railway Series

Thomas insulted Terence for having caterpillar tracks but regretted it after Terence pulled him out of a snowdrift.

Terence befriended Duck while Thomas was at the Works.

Terence did Percy's shunting work at Ffarquhar while Percy was at Knapford Harbour.

Terence helped to build a barn the day Victoria was sent back to Thomas' Branch Line. After swerving for a boulder by the Hackenbeck tunnel, Terence's trailer fell down the cutting and balanced dangerously on a bush.

Thomas & Friends

As in the Railway Series, Terence rescued Thomas when he got stuck in the snow. He later helped Mrs. Kyndley when her house was snowed up and looked after it when she went with the engines to a Christmas Party. In the second series, Terence befriended Duck while Thomas was at the works and attended the Christmas Party at Tidmouth.

When a storm destroyed much of the forest, Terence helped with the planting of new trees and assured Henry that the forest would look better than ever before. Later, when Bertie got stuck in the mud at the Vicar of Wellsworth's party, Terence used strong ropes to pull him out. During the winter, when villagers were stranded by snow, Terence helped them by ploughing the snow away.

In the fifth series, he warned James about the damage that trees can do and reminded Percy that Mrs. Kyndley's daughter was to get married. He was also seen working at Boulder Quarry.

In the sixth series, he helped clear away fallen rock on the line which had derailed Thomas and almost Toby. He was later seen ploughing in a field when Duncan lost his whistle trying to surprise him.

In the seventh series, he helped clear away a tree that had fallen on the line and pulled Elizabeth out of the snow.

In The Great Discovery, when Thomas went missing, Terence helped with the search for him and once Thomas was found, Terence along with Trevor informed Harvey of the news.

Once, when Terence was collecting Christmas trees for the holiday market, Thomas had requested a large tree for the party at Ulfstead Castle. Terence took a shortcut across a frozen lake to get to the tree, but on the way back, the ice began to break. Thomas managed to pull Terence free from the water, but the tree was lost. 

Sometime later at McColl Farm, he stared confused at some diesel parts that Rebecca had dropped out there and took the fruit and vegetable train that Paxton was supposed to collect, unaware that this was part of Diesel´s trick until Rebecca told Sir Topham Hatt about what Diesel did.


Terence is an assertive, orange tractor with caterpillar tracks. The engines find these very unusual, but Terence is very capable of proving that he does not need rails and that his tracks allow him to go practically anywhere. He takes any teasing in the name of fun and is happy to get on with his job, usually partaking in agricultural work. Terence never hesitates to assist in emergencies or sticky situations, road or rail, due to his helpful, forgiving nature. His tracks are particularly invaluable in harsh winter conditions when snow can affect transport across the Island. He may be slow, but he is versatile, adaptable and helpful. He can usually be found transporting agricultural produce or cheerily ploughing fields beside Thomas' branch line. Sometimes, though, he can get a little overconfident and forget to listen to his own advice: "You have to be sensible if you want to stay safe!"

Technical Details


Terence is based on a Caterpillar Model 70; the largest and last design of petrol-powered tractors in the Caterpillar Tractor Company's range. The Caterpillar Tractors share the same basis.
