Wilson

Wilson is a Diesel. He is currently a trainee and has been since the first series. He is considered the main character of the program.

Persona
Wilson is a lively, mixed-traffic engine with lots of enthusiasm, but this eagerness isn't always matched by his ability to pay attention to instructions, so he often finds himself in deep water. For example, he may pay attention to the dispatch board to see which tunnel to take, but as he emerges on the other side, he realizes that he forgot to listen to where he's supposed to be going! He also isn't very good at concentrating and can lose focus from something as small as a butterfly. Wilson sometimes gets frustrated that he's not as strong as Brewster or as fast as Koko, but he just doesn't fully understand his own special talents yet. Wilson has lots of confidence in his everyday surroundings, but is suddenly unsure when presented with something new or unfamiliar. In season 4, he joins Jackman and Calley in the Chug patrol.

Basis
Wilson is based on the EMD F3, an American Railway Diesel.
