Mavis/Behind the Scenes

Background Information
Mavis is named after the Rev. W. Awdry's neighbour in Rodborough, Stroud. Awdry's model of Mavis was actually made in 1962. It was not until ten years later in 1972 that Mavis debuted in the Railway Series itself. As Tramway Engines became the last book written by Wilbert Awdry for the Railway Series, Mavis became the last character Wilbert Awdry created before he retired.
