Awdry's brother, George, revealed that tramway regulations required the fitting of cowcatchers and sideplates for railway locomotives running on tracks alongside roads, and the story "Thomas in Trouble" (published in 1952, the year steam trams were replaced) evolved to provide a reason for Toby being summoned to Sodor. The story includes a description of Toby's final journeys on the line: This was a common occurrence during the closing of real railway lines; demand decreased to an unprofitable amount, but services were often full for the last workings of steam. On Awdry's model railway, Toby was represented by a Y6, an 0-4-0 locomotive similar to but smaller than the J70 and better suited to the 4-wheel motor bogie available to power the model. In 1961, Awdry wrote an article for Railway Modeller magazine on the construction of this locomotive. Christopher Awdry has said that Toby is his favourite character, partly because he was there when his father received the inspiration to create him, but also because as a child he had travelled in the cab of two J70s. Rev. W, Awdry served as parish priest in two parishes in Cambridgeshire, the county associated with Toby the Tram Engine. First, he was Rector of Elsworth with Knapwell from 1946 to 1953, then he was Vicar of Emneth from 1953 until 1965 when he retired from full-time ministry and moved to Stroud, Gloucestershire. The Railway Series Toby is introduced in the seventh book in The Railway Series. The first story, Toby and the Stout Gentleman, describes the closure of Toby's branch line due to the lack of passengers and freight. Shortly before the line was going to close, a "stout gentleman" arrived on a holiday with his family; the children rode on Toby every day for a fortnight and the stout gentleman gave Toby's crew a present. The day after the Tramway closed, ironically after an overcrowded final journey by Toby and Henrietta, a letter arrived from the stout gentleman which was to give Toby a reprieve. In Thomas in Trouble, Thomas encounters an officious policeman, who says that, when running from the quarry, along public roads, engines who have the right to go on public roads must be fitted with cowcatchers and sideplates for safety to prevent people and animals from getting killed if they should have the right to stray onto the line.
