|Mrs. Dowager Hatt|
In her first visit to Sodor, Gordon was charged with bringing her to Kirk Ronan. She later visited Sodor several times, including once to celebrate her birthday.
During her youth, she used to be a very good opera singer, though her son does not like hearing it.
In the Driver Perkins segments of the Thomas and the Runaway Kite (DVD) it is revealed that she also has a parrot named Beaky.
She later attended Sir Robert Norramby's Christmas Luncheon and became cross when Sir Topham Hatt, failed to show up for a lunch date and went out to find him, on board Thomas.
She is a bit of a thrill-seeker and hates going slow and resting. She hates nonsense and is shown not to believe in mythical creatures such as the abominable snowman. She loves her son, Sir Topham and opera singing.

- In the twelfth season and onwards, her eye colour changed from brown to blue.
- Her name, Dowager, means someone who is a widow with a noble title so this means that her husband is deceased.
- Since the switchover to CGI, Dowager Hatt appears to have lost a significant amount of weight.
