Wilsonis an American diesel-electric hybrid, and the main protagonist of the show. He is currently an advanced apprentice.
Wilson is a lively, mixed-traffic engine with lots of enthusiasm. He has ADHD (Attention Deficit Hyperactivity Disorder), which means he has a difficulty 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! This can be a result of short term memory loss.
He also isn't very good at concentrating and can lose focus from something as small as a butterfly - for which he finds unusually fascinating. 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. he helps Jackman and Calley in the Chug patrol sometimes.
