Tabitha Troodon, also known as Mrs. Conductor (Sra. Madre del Revisor or Madre del Revisor in Spain) (voiced by Tabitha St. Germain) is a female troodon. She is the wife of Trevor Troodon, the mother of Mr. Conductor and grandmother of Gilbert, and Sydney. Unlike most troodons she's energetic, loud, playful, and fun-loving. She also used to run the Dinosaur Train. She visits on special occasions. She is best friends with Don who likes her games and fun personality. Her son gets fed with her energy, embarrassment, sneaking up on him and saying his line, such as "ALL ABOARD!" And sometimes when her son is having a day-off, she does his job for him.
