Belle is a firefighting tank engine.


Belle arrived on Sodor to help out with any fires and joined the Sodor Search and Rescue Center. She also recommended Flynn to help her out with fires on Sodor. She helped put out the fire on the Dieselworks. Later, she wanted to be friends with Toby, but she was too loud and big, so instead she tried to be gentle so Toby would like her.


Belle is lively, loud, and proud, with a big personality. While she may come across as bolshy, highly self-assertive, and overwhelming, Belle will always have the best of intentions at heart. She always wants to do her best and be the best she can be, causing her to be daring, energetic, and bursting with enthusiasm. But Belle is happy to talk to any engine or vehicle and, although she may be quick to jump in with her own ideas, always tries to understand, help, and be kind to others. As a result, she is a very likable engine, so much so that even Cranky gets on with her. She gets on well with Thomas and can even hold a civil conversation with Diesel, but she works especially well with Flynn, when helping him to tackle fires and is always there to support him should he make a mistake. Although fighting fires is always high on her list of priorities, Belle has also been known to perform goods duties about the railway.


Belle is painted blue with red and brass fittings. She has the number 6120 painted in gold and a crest consisting of a flame, two dolphins, and a crown painted on her sides.




  • Belle's name is French for "pretty", and references the bell on her boiler.
