US than in the UK. The Fat Controller's name was revealed to be Bertram by Alicia Botti, the famous opera singer, in "Play Time", and by his mother Dowager Hatt in "Percy's Parcel", "Jitters and Japes", "Edward the Hero" and "Stop that Bus!". Mode of dress In his iconic top hat and morning suit, the Fat Controller looks rather old-fashioned and formal. In the television series, Sir Topham's suit has often been used for comic effect, being augmented with scarf and mittens in winter. The series plays on the outdated nature of this outfit, giving Sir Topham an entire wardrobe of old-fashioned and formal clothes for occasions when he is not "on duty". In the Series 8 episode "Halloween", he is shown wearing pyjamas and a nightcap, and in the Series 9 and 10 episodes "Flour Power" and "Sticky Toffee Thomas" he is briefly shown wearing a wizard costume. In yet another episode, he is shown wearing a kilt, a gift from a visiting Scottish Lord. In various CGI episodes, he dresses like Santa Claus. Sir Topham's household Wife: Lady Hatt Lady Jane Brown Hatt helps her husband run the railway, and is happiest when she sees new lines opened. She has had some special birthday parties. She likes the railway, but had a certain dislike of Annie and Clarabel, calling them beach huts. Later, she took a liking to them, after they got new coats of paint. Although her husband runs a railway, she likes a day out in their car or on a boat.
