}Sir Topham Hatt, nicknamed "The Fat Controller" (previously known as "The Fat Director"), is the manager of the North Western Railway and is a father figure to his engines.

The Fat Controllers[]
So far, there have been three controllers in charge of the North Western Railway.
Sir Topham Hatt I (1880-1956)[]
Sir Topham Hatt was apprenticed at the Great Western Railway's Swindon Works in 1894 at the age of fourteen. During his time there, he seems to have struck up a friendship with William A. Stanier, a fellow apprentice. The story current at Crovan's Gate Works is that on at least one occasion, perhaps more, the future Sir Topham was able to help the future Sir William to escape the consequences of what might have been a serious scrape. Due to his training at Swindon, he always admired things Great Western.
He came to Sodor in 1901 and joined A. W. Dry & Co., a firm of drainage engineers, at Tidmouth. On their recommendation, he became an engineer to the Tidmouth, Knapford and Elsbridge Light Railway in 1910, the Tidmouth, Wellsworth & Suddery in 1912 and the North Western Railway upon its formation in 1914. On the North Western Railway, he rose to be General Manager in 1923, Managing Director in 1936 and upon Nationalisation in 1948, he was created a baronet on his appointment as Chairman of the Regional Executive.
For A.W. Dry & Co., he built a series of four vertical boiler engines known as Coffee Pots between 1905 and 1908, which were used by the TK&ER. After an Autumn gale in 1908, he directed unemployed miners in cutting a tunnel through the ridge south of Tidmouth. In 1915, for the NWR, he designed a double tracked Scherzer Rolling Lift Bridge of 120 ft span to cross the Walney Channel. Sometime after this, he was appointed a director of the Company.
When the Railway was suffering from a locomotive crisis in the early 1920's, he was responsible for acquiring new engines. During this time, he made one of his rare bad bargains when he purchased Henry instead of the Robinson Atlantic he wanted. He remembered the mistake with sorrow for the rest of his days and was so angry at having been “done” that he would never admit who it was who had swindled him. No-one was better pleased than Topham Hatt when the Killdane accident occurred in 1935. Using his connections with William Stanier, now CME of the LMS, he was able to have Henry completely rebuilt at Crewe Works.
In 1953, when The Queen visited Sodor in Coronation year he had the honour of welcoming her to Tidmouth, having been previously presented to Her Majesty by Viscount Harwick, the Governor, who was also his son-in-law.
He retired in 1954 in favour of his son Charles, whom the Board had no hesitation in electing as his successor. It is no exaggeration to say that the present prosperity of the Railway is almost entirely due to his initiative and resource.
He married Jane, sister of Sir Handel Brown in 1910 and they had two children, Barbara Jane (born 1911), who married Henry Regaby in 1938 and Charles Topham. He died at Wellsworth in 1956 at the age of 76.
In The Three Railway Engines and Thomas the Tank Engine, he was nicknamed "The Fat Director" before his nickname changed to "The Fat Controller" in James the Red Engine.
Sir Charles Topham Hatt II (1914-1997)[]
Sir Charles Topham Hatt was the second Fat Controller from 1954 to 1984, when he retired in favour of his own son.
Charles Topham Hatt was educated at Abbey School, Cronk and from there went to Crewe Works as an engineering pupil under Mr. William Stanier in 1932. He was present during Henry's rebuilding in 1935. In 1937, he was recommended for railway service overseas by Mr. Stanier, but he returned in 1939 to enlist in the Royal Engineers, serving with them throughout the Second World War. He was demobilised in 1945 with the rank of Colonel.
He spent a further period overseas, before returning to Sodor in 1952 to become Chief Mechanical Engineer at Crovan's Gate Works and general assistant to his ageing father. Following his father's retirement in 1954, the Board had no hesitation in electing him as Controller.
During his period of office, he began improvements to the harbour at Knapford, planned by his father and reopened the Arlesburgh branch in 1965/6, being responsible for the construction of the Arlesdale Railway and for establishing the ballast consortium which uses it.
His cousin, Sir Handel Lloyd Brown II, was born in 1924. He married Amanda Croarie in 1940 and they had two children, Stephen Topham, born in 1941 and Bridget, born in 1943. Charles inherited his father's baronetcy in 1956.
