Trivia

 * Belle's name is French for "pretty" and references the bell on her firebox.
 * Despite being voiced by the same actress in both dubs, Teresa Gallagher gives Belle an American accent in the US dub as opposed to her British accent in the UK dub. She is the first character to be in this situation with the second character being James in the twenty-first season.
 * Belle's Minis prototypes share the same mould as Rosie, therefore incorrectly depicting her as an SR USA Class 0-6-0T. This was fixed on the final produced toys, depicting her as a BR Standard Class 4MT tank engine.
 * In the nineteenth season, the frame around Belle's bell changed from black to brass.
 * Belle is the first female engine to be introduced in a CGI special.
