Caitlin is a streamlined engine, designed for speed. Along with her friend Connor, Caitlin is an excitable and energetic character, who likes to be busy and loves to race. Both Caitlin and Connor are friendly and eager to get other engines to join in the fun with them. Caitlin is particularly impatient and restless if she has nothing to do. She would rather be racing than sit in a station and be idle. She rarely seems to lack energy.
