It is a train, not sure what engine though. Mr Simmonds is being a bit Coy about what he exactly does, but I know it is something to do with the railways. I will hazard a guess and say that he teaches people to drive them...?
By the way, is the shot in Wales taken by Llyn Gwynant at all. Superb looking hound that Mr Simmonds you must miss him big style. people who have never owned a dog ( or any pet really ) do not know how attached you get and emotionally involved throughout their unfortunately, shorter life than ours.
