|The Fat Controller|
Sir Topham Hatt or The Fat Controller considers himself a gentleman of merit, with a railway exquisitely fine, and has no favourite engines.
Prior to his becoming Controller of the North Western Railway, Sir Bertram Topham Hatt owned a Sentinel steam lorry named Elizabeth, who notes that he wasn't the best driver. When he was a young man, Edward always took him aboard an old coach on his birthday. The Fat Controller later received his knighthood for his service to the railway industry. Sir Topham was also the controller of the Skarloey Railway, until Mr. Percival was hired to help him manage the ever-increasing size of his railway industry. In the Sixteenth season, he gained a track inspection car named, Winston, which is often used as a private transportation vehicle on the railway.
Sir Topham Hatt married Lady Hatt, and is the grandfather of Stephen and Bridget Hatt.
As well as owning several engines, he owns a cat, two cars, and lives a mansion somewhere on the outskirts of Wellsworth. However, when the engines misbehave, it's Edward that the Fat Controller turns to in order to calm everyone down and restore order.
The Fat Controller is seen as a firm but fair character. He can be strict, but also shows a fatherly side to the engines. He is quite a strong character and will remind the engines that he is in charge when they start to rebel against his authority. He does not stand bullying and, even though he is usually serious, he does enjoy a good laugh. Despite his kindness and fairness, however, there are times where he berates the engines for things beyond their control.
The Fat Controller is a short, stout gentleman. He is usually dressed in a black suit with grey trousers, a cream or yellow waistcoat, a black tie, and a top hat. He is bald and has brown eyes.
