Dowager Hatt

"Hold on to your hats!"

- Dowager Hatt's catchphrase

Mrs. Dowager Hatt is the Fat Controller and Sir Lowham Hatt's mother, Stephen and Bridget Hatt's great-grandmother, and Lady Hatt's mother-in-law. She owns a Dalmatian, which she renamed "Gremlin" after her adventure with Gordon's "gremlins". She is a bit of a thrill-seeker and hates going slow and resting.

In the Driver Perkins segments of the Thomas and the Runaway Kite DVD it is revealed that she also has a parrot named Beaky.

As of the CGI series, Dowager Hatt appears to live near Maithwaite.
