"Look at that! The back engine must be the strongest and the best!"
— Stephen Hatt, Edward the Very Useful Engine, sixth season
Stephen Topham Hatt

Stephen Topham Hatt (born 1941) is Sir Topham and Lady Hatt's grandson and Bridget's older brother. In The Railway Series, he took over his father's role as controller of the North Western Railway in 1984 and became Sir Topham Hatt III in 1997.

Bio in the Railway Series

The Hatts spent a long holiday on Toby's old line in East Anglia. Stephen was excited when he first met Toby, but Bridget accidentally offended him by assuming he was an electric tram.

He became the Fat Controller in 1984, succeeding to his father's baronetcy in 1997. In 1970, he married Helen Margaret, a distant cousin and granddaughter of the Reverend Nicholas Dreswick, the much-respected historian of Sodor. They had three children: Richard Topham, born in 1972 and no doubt destined to be Sir Topham Hatt IV (his father will be seventy-four in 2015, though he has, as yet, given no hint of retiring), Charles Nicholas (1974-) and Emily Helen (1977-).

With great skill, he masterminded the arrangements for the royal visit in 1995, when he welcomed the Prince of Wales on his visit to Sodor.

Bio in the Television Series

Stephen had never grown up to be controller, and has always remained as about the same age. He was amongst the boys who teased Daisy about bull's-eyes, and was also amongst the boys who teased Sir Handel about George. He and Bridget helped Toby discover an old castle. He thought that Edward was the strongest and the best, after Edward pushed Duck, Gordon, and their trains into Knapford Station. He and Bridget flew a kite, which got blown away, but Thomas, along with Charlie, Percy, Edward, and Emily retrieved it. He and Bridget later caught chickenpox, convincing Henry that engines could catch chickenpox as well.
