When Toby first came to Sodor, he was old but hardworking and knew enough about running a branch line to justify running Thomas' with Thomas and Daisy after Percy's accident with the trucks. He is also savvy enough to control the trucks. However, his advanced age and design means that he is weaker than the other engines. Toby is a bit nervous about the capabilities of his work and uncertain about being an old steam tram, believing that he is not a proper engine, only good enough as a museum piece and not really special at all. Toby enjoys listening to the birds in the birdhouse next to his shed. Lately, Toby has been wiser, with a more jovial personality, having more subtle shades of nervousness.
