Fergus

Fergus is a railway traction engine

Bio
Fergus primarily works at the Sodor Cement Works on the Kirk Ronan Branch Line, and is thus called "the pride of the Cement Works".

Fergus was once sent to work at the Anopha Quarry with Mavis, Bill and Ben. Bill and Ben immediately began to get annoyed with Fergus telling them to "Do it right", so when they brought a rock crusher, they decided to do the opposite of what he told them to do, thus, to "Do it wrong". However, their naughty actions nearly caused them to get caught in a landslide caused by blasting and their heavy rock crusher, but Fergus managed to push them out of the way, only to end up in the rockslide himself. The twins managed to help Fergus out and apologised for their bad behaviour.

Personality
Fergus knows the rulebook off by heart, and his catchphrase is "Do it right!" His insistence on doing everything absolutely according to the rules can annoy the other engines, but he is a decent engine at heart and will not hesitate to help others in trouble. He is also friendly to nearly everyone he meets.

Trivia

 * According to the official website, Fergus' flywheel can be used as power tools such as a saw, drill or pump. It has also powered a generator in the past.
