" Well, thank you, my dear. I knew this was my special birthday party, but I didn't know it was fancy dress!"
— Lady Hatt greeting her husband, Lady Hatt's Birthday Party, fifth season
Lady Jane Hatt
Lady Jane Hatt (née Brown) is Sir Topham Hatt's wife and the sister of Sir Handel Brown I.
Lady Hatt occasionally helps her husband with railway business, and the engines sometimes go to extreme lengths to help throw parties for her birthday. She likes the railway, but had a certain dislike for
Annie and Clarabel until they were cleaned and repainted. Although her husband runs a railway, she likes a day out on a boat or in their car.
The engines are extremely fond of her and like when she visits the railway or rides in one of their coaches. A kind and gentle woman, Lady Hatt usually praises the engines for their good deeds.
