Along with Connor, Thomas, Percy and James, she helped with the search of Stephen before Ulfstead Castle's opening. Caitlin once had to spend the night on Sodor and became too excited to listen to Sir Topham Hatt's advice. During her night on Sodor, she took the mail train and the Flying Kipper. Unfortunately, she did not take others into consideration and ended up waking lots of people up.
Annie and Clarabel, who were in the yard waiting for Thomas, were accidentally coupled up to Caitlin and she took them to the Mainland, but was stopped by Hiro, who brought them back to Thomas.
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. Caitlin and Connor were introduced to the island to bring passengers from the Mainland. They zip on and off the island frequently using the Vicarstown Rolling Bridge.
Caitlin is based on the Baltimore and Ohio Railroad streamlined President Class.
Caitlin is painted fuchsia with light grey and light blue lining

- In real life, Caitlin would be too large for the British loading gauge. However, she seems to have been re-scaled to avoid any animation issues.
- Her valve gear and siderods are not animated properly. Their movement would be jammed in real life.
- Caitlin has been modified for use of British rail lines, given a screwlink coupling and buffers at the back.
- Members of Caitlin's class have been photographed posed alongside the Duchess of Hamilton during the latter's 1938-39 U.S. tour.
