Fergus is an Aveling & Porter railway traction engine who mainly works at the cement works and thus calls himself 'The Pride of the Cement Works". He is painted blue-purple with red wheels, and although he vaguely resembles Trevor the Traction Engine, Fergus runs on rails, unlike Trevor.

Fergus knows the Rule Book by heart, and his catchphrase is "Do it right!" His insistence on doing everything absolutely according to the rules can annoy the other engines. However, he is a decent engine at heart and will not hesitate to help other engines who are in trouble. His catchphrase is "Do It Right!"

His flywheel can be hooked up to machinery, and this feature is first seen in the Season 7 episode Salty's Stormy Tale, when he uses it to save a ship from crashing into the rocks by powering the lighthouse lamp generator.
