What he means is...

— Dart in virtually every episode he and Den appear in

Dart is a Diesel who helps out Den at the Dieselworks.


In Adventures on Rails, Dart was brought to Sodor to help move parts at the Dieselworks. He usually causes havoc there, much to Den and Diesel 10's annoyance.


Dart works at the Vicarstown Dieselworks to support and assist Den. Den and Dart have worked together for so long that Dart can often guess what Den is thinking before he can get it out himself. Although not so much the thinker of the duo, he is usually the doer and can be the chattier of the two. He quickly buzzes about the Dieselworks, occasionally bashing, crashing, and clanging into things. He can be heard to grumble "Dizzy Diesels!" when something goes wrong. Dart is very able in his work and a valuable team player. Despite being small in size, he is feisty and fast. Dart also like jokes, sometimes to the annoyance of the other Diesels. If feeling bothered, particularly by the steam engines, Dart is far from devious, but can get grumpy, gruff, irritable, and sometimes cheeky too, but otherwise he is the quick-witted assistant of the Dieselworks.


Dart is painted yellow and red with white lining and the Dieselworks logo on the sides of his cab.

In Thomas the Slender Engine

Dart inhabits Vicarstown Dieselworks (Dusk).

He was voiced by the late Mickey Rooney.
