On Awdry's model railway,[REF] 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.
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.
