Caitlin

Caitlin is a fast streamlined engine from the Mainland Railway, who was designed for speed. She also has her own rake of coaches painted in a similar colour scheme to her own. 
==Bio==
Caitlin loves to challenge the other engines to a race and has a tendency to get a little-overexcited. She, along with Connor, regularly transport passengers from the Mainland to Ulfstead Castle. 
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 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.
==Persona==
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 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. Connor and Caitlin were introduced to the island to bring passengers from the Mainland. They zip on and off the island frequently using the Vicarstown Rolling Bridge.
