Azul appears to be a freelance design. Therefore, he is not based on a specific prototype.


  • Just like Isa and Little Star, Azul got Character Find in only two episodes. Strangely whenever he blows his whistle, it's not his whistle, but instead is the whistle from the Big Green Train from Choo-Choo!.
  • From Choo-Choo! until A Present For Santa, he was voiced by Jordan Smith-Howie. Beginning with the end credits of Whose Birthday is It? and the episode The Lost City, he was voiced by Phillip Miller.
  • He is actually a rail motor mixed steam locomotive, not an ordinary train.
  • Azul’s whistle is a stock sound effect from the Sound Ideas website.
  • Azul no longer appears in Season 6 and his 3D look in Seasons 7 and 8.
