Caitlin is a fast streamlined engine.


Caitlin was first seen racing past Gordon and Spencer in King of the Railway. Later, she along with Connor raced Gordon and Spencer, and also at the end of the film. She also joined the search party when Stephen got lost in the mine.


Along with her friend Connor, Caitlin is an excitable and energetic character, who likes to be busy and loves to race. Both Connor and Caitlin 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.


Caitlin is painted a purplish red colour with light grey and light blue lining.




  • Her valve gear and siderods are not animated properly. Their movement would be jammed in real life.
