Belle is a big tank engine on the North Western Railway. She is modified with water cannons and is part of the Sodor Search and Rescue Team.



Belle is a big, bold, blue tank engine, who is fitted with two water cannons atop her tanks, from which she can shoot water to fight fires. 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 likeable 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 top of her list of priorities, Belle has also been known to perform goods duties about the railway.


Belle is painted royal blue with red and gold lining, brass fittings and red water cannons. She has the number "6120" painted on her side tanks in gold and a crest consisting of a flame, two dolphins and a crown painted on the sides of her bunker. Her wheels are red with blue rims.


  • Belle's name is French for "pretty", and references the bell on her boiler.
  • She has been modified with water cannons, a brass bell and electric headlamps on her bufferbeam and above her smokebox, along with extended side tanks. She also has a special water tender.
